# Blockers
|
||||
|
||||
Blockers are part of the {{crowdsec.name}} full stack integration. They allow you to block an IP at any level of your infra/stack.
|
||||
|
||||
You can explore [available {{plugins.name}} on the hub]({{hub.plugins_url}}).
|
||||
|
||||
Some core {{plugins.name}} are documented here :
|
||||
|
||||
- [nginx lua helper](/blockers/nginx/installation/)
|
||||
- [netfilter a-la-fail2ban](/blockers/netfilter/installation/)
|
||||
- [wordpress plugin](/blockers/wordpress/installation/)

</details>
|
||||
|
||||
- `SOURCE` is the source of the decision :
|
||||
- "local" : the decision has been taken by {{crowdsec.name}}
|
||||
- "cli" : the decision has been made with {{cli.name}} (ie. `{{cli.name}} ban ip 1.2.3.4 24h "because"`)
|
||||
- "api" : the decision has been pushed to you by the API (because there is a consensus about this ip)
|
||||
- `IP` is the IP or the IP range impacted by the decision
|
||||
- `REASON` is the scenario that was triggered (or human-supplied reason)
|
||||
- `BANS` is the number of "active" remediation against this IP
|
||||
- `COUNTRY` and `AS` are provided by GeoIP enrichment if present
|
||||
- `EXPIRATION` is the time left on remediation
|
||||
|
||||
|
||||
## Remove a ban
|
||||
|
||||
|
||||
> delete the ban on IP `1.2.3.4`
|
||||
|
||||
```bash
|
||||
{{cli.bin}} ban del ip 1.2.3.4
|
||||
```
|
||||
|
||||
> delete the ban on range 1.2.3.0/24
|
||||
|
||||
```bash
|
||||
{{cli.bin}} ban del range 1.2.3.0/24
|
||||
```
|
||||
|
||||
|
||||
## Add a ban manually
|
||||
|
||||
> Add a ban on IP `1.2.3.4` for 24 hours, with reason 'web bruteforce'
|
||||
|
||||

{{cli.bin}} allows you install, list, update/upgrade and remove configurations : parsers, enrichment, scenarios.
|
||||
|
||||
The various parsers, enrichers and scenarios installed on your machine makes a coherent ensemble to provide detection capabilities.
|
||||
|
||||
_Parsers, Scenarios and Enrichers are often bundled together in "collections" to facilitate configuration._
|
||||
|
||||
Parsers, scenarios, enrichers and collections all follow the same principle :
|
||||
|
||||
- `{{cli.bin}} install parser crowdsec/nginx-logs`
|
||||
- `{{cli.bin}} update collection crowdsec/base-http-scenarios`
|
||||
- `{{cli.bin}} remove scenario crowdsec/mysql-bf`
|
||||
|
||||
> Please see your local `{{cli.bin}} help` for up-to-date documentation
|
||||
|
||||
|
||||
## List configurations
|
||||
|
||||
```
|
||||
{{cli.bin}} list
|

# FREQUENTLY ASKED QUESTIONS
|
||||
|
||||
## What is {{crowdsec.name}} ?
|
||||
|
||||
{{crowdsec.Name}} is a security open-source software. See the [overview](/#what-is-crowdsec)
|
||||
|
||||
|
||||
## What language is it written in ?
|
||||
|
||||
{{crowdsec.Name}} is written in [Golang](https://golang.org/)
|
||||
|
||||
## What licence is {{crowdsec.name}} released under ?
|
||||
|
||||
{{crowdsec.Name}} is under [MIT license]({{crowdsec.url}}/blob/master/LICENSE)
|
||||
|
||||
## How fast is it ?
|
||||
|
||||
{{crowdsec.name}} can easily handle 5k+ EP/s on a rich pipeline (multiple parsers, geoip enrichment, scenarios and so on). Logs are a good fit for sharding by default, so it is definitely the way to go if you need to handle higher throughput.
|
||||
|
||||
If you need help for large scale deployment, please get in touch with us on the {{doc.discourse}}, we love challenges ;)
|
||||
|
||||
|
||||
## Is there any performance impact ?
|
||||
|
||||
As {{crowdsec.name}} only works on logs, it shouldn't impact your production.
|
||||
When it comes to {{plugins.name}}, it should perform **one** request to the database when a **new** IP is discovered thus have minimal performance impact.
|
||||
|
||||
## Which information is shared from my logs ?
|
||||
|
||||
|
||||
Our aim is to build a strong community that can share malevolent attackers IPs, for that we need to collect the bans triggered locally by each user.
|
||||
|
||||
The signal sent by your {{crowdsec.name}} to the central API only contains meta-data about the attack, including :
|
||||
|
||||
- Attacker IP
|
||||
- Scenario name
|
||||
- Time of start/end of attack
|
||||
|
||||
You can find the specific list [here]({{crowdsec.url}}/blob/master/pkg/types/signal_occurence.go)
|
||||
|
||||
## How to add whitelists ?
|
||||
|
||||
You can follow this [guide](/write_configurations/whitelist/)
|
||||
|
||||
## How to set up proxy ?
|
||||
|
||||
Setting up a proxy works out of the box, the [net/http golang library](https://golang.org/src/net/http/transport.go) can handle those environment variables:
|
||||
|
||||
* `HTTP_PROXY`
|
||||
* `HTTPS_PROXY`
|
||||
* `NO_PROXY`
|
||||
|
||||
Since {{cli.name}} uses `sudo`, you just this line in `visudo` after setting up the previous environment variables:
|
||||
|
||||
```
|
||||
Defaults env_keep += "HTTP_PROXY HTTPS_PROXY NO_PROXY"
|
||||
```
|
||||
|
||||
## How to report a bug ?
|
||||
|
||||
To report a bug, please open an issue on the [repository]({{crowdsec.bugreport}})
|
||||
|
||||
## I need some help
|
||||
|
||||
Feel free to ask for some help to the {{doc.community}}.

||||

||||

|
|||
{{crowdsec.Name}}'s main goal is to crunch logs to detect things (duh).
|
||||
You will find below an introduction to the concepts that are frequently used within the documentation.
|
||||
|
||||
## Acquisition
|
||||
|
||||
[Acquistion configuration](/guide/crowdsec/acquisition/) defines which streams of information {{crowdsec.name}} is going to process.
|
||||
|
||||
At the time of writing, it's mostly files, but it should be more or less any kind of stream, such as a kafka topic or a cloudtrail.
|
||||
|
||||
Acquisition configuration always contains a stream (ie. a file to tail) and a tag (ie. "these are in syslog format" "these are non-syslog nginx logs").
|
||||
|
||||
## Parsers
|
||||
|
||||
For logs to be able to be exploited and analyzed, they need to be parsed and normalized, and this is where parsers are used. In most cases, you should be able to find the relevant parsers on our {{hub.htmlname}}.
|
||||
|
||||
A parser usually has a specific scope. For example, if you are using [nginx](https://nginx.org), you will probably want to use the `crowdsecurity/nginx-logs` which allows your {{crowdsec.name}} setup to parse nginx's access and error logs.
|
||||
|
||||
You can as well [write your own](/write_configurations/parsers/) !
|
||||
|
||||
## Enrichers
|
||||
|
||||
Enrichment is the action of adding extra context to an event based on the information we already have, so that better decision can later be taken. In most cases, you should be able to find the relevant enrichers on our {{hub.htmlname}}.
|
||||
|
||||
The most common/simple type of enrichment would be geoip-enrichment of an event (adding information such as : origin country, origin AS and origin IP range to an event).
|
||||
|
||||
Once again, you should be able to find the ones you're looking for on the {{hub.htmlname}} !
|
||||
|
||||
## Scenarios
|
||||
|
||||
Scenarios is the expression of a heuristic that allows you to qualify a specific event (usually an attack). In most cases, you should be able to find the relevant scenarios on our {{hub.htmlname}}.
|
||||
|
||||
While not going [into details](/references/scenarios/), a scenario often evolves around several central things.
|
||||
|
||||
(Let's take "we want to detect ssh bruteforce" as an example!)
|
||||
|
||||
- A filter : to know which events are elligible ("I'm looking for failed authentication")
|
||||
- A grouping key : how are we going to "group" events together to give them a meaning ("We are going to group by source IP performing said failed authentication")
|
||||
- A rate-limit configuration including burst capacity : to qualify an attack and limit the false positives, we are characterizing the speed at which events need to happen (For a ssh bruteforce, it could be "at least 10 failed authentication within 1 minute")
|
||||
|
||||
You can as well [write your own](/write_configurations/scenarios/) !
|
||||
|
||||
|
||||
## Collections
|
||||
|
||||
To make user's life easier, "collections" are available, which are just a bundle of parsers and scenarios.
|
||||
In this way, if you want to cover basic use-cases of let's say "nginx", you can just install the `crowdsecurity/nginx` collection that is composed of `crowdsecurity/nginx-logs` parser, as well as generic http scenarios such as `crowdsecurity/base-http-scenarios`.
|
||||
|
||||
As usual, those can be found on the {{hub.htmlname}} !

## Finding configurations
|
||||
|
||||
As stated, {{crowdsec.name}} efficiency is dictated by installed parsers and scenarios.
|
||||
|
||||
[Please take a look at the {{hub.name}}]({{hub.url}}) to find the appropriated ones !

### **Event**
|
||||
|
||||
The objects that are processed within {{crowdsec.name}} are named "Events".
|
||||
An Event can be a log line, or an overflow result. This object layout evolves around a few important items :
|
||||
|
||||
- `Parsed` is an associative array that will be used during parsing to store temporary variables or processing results.
|
||||
- `Enriched`, very similar to `Parsed`, is an associative array but is intended to be used for enrichment process.
|
||||
- `Overflow` is a `SignalOccurence` structure that represents information about a triggered scenario, when applicable.
|
||||
- `Meta` is an associative array that will be used to keep track of meta information about the event.
|
||||
|
||||
_Other fields omitted for clarity, see [`pkg/types/event.go`](https://github.com/crowdsecurity/crowdsec/blob/master/pkg/types/event.go) for detailed definition_
|
||||
|
||||
### **Overflow or SignalOccurence**
|
||||
|
||||
This object holds the relevant information about a scenario that happened : who / when / where / what etc.
|
||||
Its most relevant fields are :
|
||||
|
||||
- `Scenario` : name of the scenario
|
||||
- `Alert_message` : a humanly readable message about what happened
|
||||
- `Events_count` : the number of individual events that lead to said overflow
|
||||
- `Start_at` + `Stop_at` : timestamp of the first and last events that triggered the scenario
|
||||
- `Source` : a binary representation of the source of the attack
|
||||
- `Source_[ip,range,AutonomousSystemNumber,AutonomousSystemOrganization,Country]` : string representation of source information
|
||||
- `Labels` : an associative array representing the scenario "labels" (see scenario definition)
|
||||
|
||||
_Other fields omitted for clarity, see [`pkg/types/signal_occurence.go`](https://github.com/crowdsecurity/crowdsec/blob/master/pkg/types/signal_occurence.go) for detailed definition_
|
||||
|
||||
|
||||
|
||||
### **Acquisition**
|
||||
|
||||
Acquisition and its config (`acquis.yaml`) specify a list of files/ streams to read from (at the time of writing, files are the only input stream supported).
|
||||
|
||||
On common setups, {{wizard.name}} interactive installation will take care of it.
|
||||
|
||||
File acquisition configuration is defined as :
|
||||
|
||||
```yaml
|
||||
filenames: #a list of file or regexp to read from (supports regular expressions)
|
||||
- /var/log/nginx/http_access.log
|
||||
- /var/log/nginx/https_access.log
|
||||
- /var/log/nginx/error.log
|
||||
labels:
|
||||
prog_name: nginx
|
||||
---
|
||||
filenames:
|
||||
- /var/log/auth.log
|
||||
labels:
|
||||
type: syslog
|
||||
```
|
||||
|
||||
The `labels` part is here to tag the incoming logs with a type. `labels.prog_name` and `labels.type` are used by the parsers to know which logs to process.
|
||||
|
||||
### **Parser**
|
||||
|
||||
A parser is a YAML configuration file that describes how a string is being parsed. Said string can be a log line, or a field extracted from a previous parser. While a lot of parsers rely on the **GROK** approach (a.k.a regular expression named capture groups), parsers can as well reference enrichment modules to allow specific data processing.
|
||||
|
||||
Parsers are organized into stages to allow pipelines and branching in parsing.
|
||||
|
||||
See the [{{hub.name}}]({{hub.url}}) to explore parsers, or see below some examples :
|
||||
|
||||
- [apache2 access/error log parser](https://github.com/crowdsecurity/hub/blob/master/parsers/s01-parse/crowdsecurity/apache2-logs.yaml)
|
||||
- [iptables logs parser](https://github.com/crowdsecurity/hub/blob/master/parsers/s01-parse/crowdsecurity/iptables-logs.yaml)
|
||||
- [http logs post-processing](https://github.com/crowdsecurity/hub/blob/master/parsers/s02-enrich/crowdsecurity/http-logs.yaml)
|
||||
|
||||
|
||||
### **Parser node**
|
||||
|
||||
A node is an individual parsing description.
|
||||
Several nodes might be presented in a single parser file.
|
||||
|
||||
### **Node success or failure**
|
||||
|
||||
When an {{event.htmlname}} enters a node (because the filter returned true), it can be considered as a success or a failure.
|
||||
The node will be successful if a grok pattern is present and successfully returned data.
|
||||
A node is considered to have failed if a grok pattern is present but didn't return data.
|
||||
If no grok pattern is present, the node will be considered successful.
|
||||
|
||||
It ensures that once an event has been parsed, it won't attempt to be processed by other nodes.
|
||||
|
||||
|
||||
### **Stages**
|
||||
|
||||
Parsers are organized into "stages" to allow pipelines and branching in parsing.
|
||||
Each parser belongs to a stage, and can trigger next stage when successful.
|
||||
At the time of writing, the parsers are organized around 3 stages :
|
||||
|
||||
- `s00-raw` : low level parser, such as syslog
|
||||
- `s01-parse` : most of the services parsers (ssh, nginx etc.)
|
||||
- `s02-enrich` : enrichment that requires parsed events (ie. geoip-enrichment) or generic parsers that apply on parsed logs (ie. second stage http parser)
|
||||
|
||||
The number and structure of stages can be altered by the user, the directory structure and their alphabetical order dictates in which order stages and parsers are processed.
|
||||
|
||||
### **Enricher**
|
||||
|
||||
An enricher is a parser that will call external code to process the data instead of processing data based on a regular expression.
|
||||
|
||||
See the [geoip-enrich](https://github.com/crowdsecurity/hub/blob/master/parsers/s02-enrich/crowdsecurity/geoip-enrich.yaml) as an example.
|
||||
|
||||
### **Scenario**
|
||||
|
||||
A scenario is a YAML configuration file that describes a set of events characterizing a scenario.
|
||||
Scenarios in {{crowdsec.name}} gravitate around the [leaky bucket](https://en.wikipedia.org/wiki/Leaky_bucket) principle.
|
||||
|
||||
A scenario description includes at least :
|
||||
|
||||
- Event eligibility rules. (For example if we're writing a ssh bruteforce detection we only focus on logs of type `ssh_failed_auth`)
|
||||
- Bucket configuration such as the leak speed or its capacity (in our same ssh bruteforce example, we might allow 1 failed auth per 10s and no more than 5 in a short amount of time: `leakspeed: 10s` `capacity: 5`)
|
||||
- Aggregation rules : per source ip or per other criterias (in our ssh bruteforce example, we will group per source ip)
|
||||
|
||||
The description allows for many other rules to be specified (blackhole, distinct filters etc.), to allow rather complex scenarios.
|
||||
|
||||
See the [{{hub.name}}]({{hub.url}}) to explore scenarios and their capabilities, or see below some examples :
|
||||
|
||||
- [ssh bruteforce detection](https://github.com/crowdsecurity/hub/blob/master/scenarios/crowdsecurity/ssh-bf.yaml)
|
||||
- [distinct http-404 scan](https://github.com/crowdsecurity/hub/blob/master/scenarios/crowdsecurity/http-scan-uniques_404.yaml)
|
||||
- [iptables port scan](https://github.com/crowdsecurity/hub/blob/master/scenarios/crowdsecurity/iptables-scan-multi_ports.yaml)
|
||||
|
||||
### **PostOverflow**
|
||||
|
||||
A postoverflow is a parser that will be applied on overflows (scenario results) before the decision is written to local DB or pushed to API. Parsers in postoverflows are meant to be used for "expensive" enrichment/parsing process that you do not want to perform on all incoming events, but rather on decision that are about to be taken.
|
||||
|
||||
An example could be slack/mattermost enrichment plugin that requires human confirmation before applying the decision or reverse-dns lookup operations.

# Installation
|
||||
|
||||
Fetch {{crowdsec.name}}'s latest version [here]({{crowdsec.download_url}}).
|
||||
|
||||
```bash
|
||||
tar xvzf crowdsec-release.tgz
|
||||
```
|
||||
```bash
|
||||
cd crowdsec-v0.X.X
|
||||
```
|
||||
|
||||
A {{wizard.name}} is provided to help you deploy {{crowdsec.name}} and {{cli.name}}.
|
||||
|
||||
## Using the interactive wizard
|
||||
|
||||
```
|
||||
sudo {{wizard.bin}} -i
|
||||
```
|
||||
|
||||
|
||||
|
||||
The {{wizard.name}} is going to guide you through the following steps :
|
||||
|
||||
- detect services that are present on your machine
|
||||
- detect selected services logs
|
||||
- suggest collections (parsers and scenarios) to deploy
|
||||
- deploy & configure {{crowdsec.name}} in order to watch selected logs for selected scenarios
|
||||
|
||||
The process should take less than a minute, [please report if there are any issues]({{wizard.bugreport}}).
|
||||
|
||||
You are then ready to [take a tour](/getting_started/crowdsec-tour/) of your freshly deployed {{crowdsec.name}} !
|
||||
|
||||
## Using unattended mode
|
||||
|
||||
> you of little faith
|
||||
|
||||
```
|
||||
sudo {{wizard.bin}} --bininstall
|
||||
```
|
||||
|
||||
This will deploy a valid/empty {{crowdsec.name}} configuration files and binaries.
|
||||
Beware, in this state, {{crowdsec.name}} won't monitor/detect anything unless configured.
|
||||
|
||||
## From source
|
||||
|
||||
!!! warning "Requirements"
|
||||
|
||||
* [Go](https://golang.org/doc/install) v1.13+
|
||||
* `git clone {{crowdsec.url}}`
|
||||
|
||||
|
||||
Go in {{crowdsec.name}} folder and build the binaries :
|
||||
|
||||
```bash
|
||||
cd crowdsec
|
||||
```
|
||||
```bash
|
||||
make build
|
||||
```
|
||||
|
||||
|
||||
{{crowdsec.name}} bin will be located in `./cmd/crowdsec/crowdsec` and {{cli.name}} bin in `cmd/crowdsec-cli/{{cli.bin}}`
|
||||
|
||||
Now, you can install either with [interactive wizard](#using-the-interactive-wizard) or the [unattended mode](#using-unattended-mode).

Please note that the `{{config.acquis_path}}` should be auto generated by the {{wizard.name}} in most case.
|
||||
|

The acquisition configuration specifies lists of files to monitor and associated "labels".
|
||||
|
||||
The `type` label is mandatory as it's later used in the process to determine which parser(s) can handle lines coming from this source.
|

|
||||
|
||||
### At startup
|
||||
|
||||
At startup, you will see the monitored files in `{{crowdsec.main_log}}` :
|
||||
|
||||

```
|
||||
|
||||
### At runtime
|
||||
|
||||
{{cli.name}} allows you to view {{crowdsec.name}} metrics info via the `metrics` command.
|
||||
This allows you to see how many lines are coming from each source, and if they are parsed correctly.
|
||||
|
||||
You can see those metrics with the following command:
|
||||
```
|
||||
{{cli.bin}} metrics
|

Enrichers are basically {{parsers.htmlname}} that can rely on external methods to provide extra contextual information to the event. The enrichers are usually in the `s02-enrich` {{stages.htmlname}} (after most of the parsing happened).
|
||||
|
||||
Enrichers functions should all accept a string as a parameter, and return an associative string array, that will be automatically merged into the `Enriched` map of the {{event.htmlname}}.
|
||||
|
||||
!!! warning
|
||||
At the time of writing, enrichers plugin mechanism implementation is still ongoing (read: the list of available is currently hardcoded).
|
||||
|
||||
|
||||
As an example let's look into the geoip-enrich parser/enricher :
|
||||
|
||||
It relies on [the geolite2 data created by maxmind](https://www.maxmind.com) and the [geoip2 golang module](https://github.com/oschwald/geoip2-golang) to provide the actual data.
|
||||
|
||||
|
||||
It exposes three methods : `GeoIpCity` `GeoIpASN` and `IpToRange` that are used by the `crowdsecurity/geoip-enrich`.
|
||||
Enrichers can be installed as any other parsers with the following command:
|
||||
|
||||
```
|
||||
{{cli.bin}} install parser crowdsecurity/geoip-enrich
|
||||
```
|
||||
|

|
||||
|
||||
#### `log_level:`
|
||||

|
||||
* `backend:` : the path where all {{crowdsec.Name}} backend plugins (database output, ...) will be located.
|
||||
|
||||
## acquis.yaml
|
||||
|
||||
This is the file that tells which streams (or files) {{crowdsec.name}} is reading, and their types (so that it knows how to parse them). If you're lucky, this file should be auto-generated by the wizard.
|
||||
|
||||
You can find details on the configuration file format [here](/guide/crowdsec/acquisition/).
|
||||
|
||||
|
||||
## api.yaml
|
||||
|
||||
Name is self-explanatory : it holds API configuration.
|
||||
|
||||
This file should never be edited by a human : the wizard will deploy safe default for it, and {{cli.name}} will alter it on your behalf when you register or enroll your machine.
|
||||
|
||||
You can look into it, and you should see :
|
||||
|
||||
- url endpoints
|
||||
- login and password (auto-generated by your machine upon registration)
|
||||
|
||||
To get new credentials :
|
||||
```bash
|
||||
{{cli.name}} api register
|
||||
```
|
||||
Or if you loose your credentials:
|
||||
```bash
|
||||
{{cli.name}} api reset
|
||||
```
|
||||
|
||||
|
||||
## profiles.yaml
|
||||
|
||||
The profiles is what allows you to decide how do you react when a scenario is triggered :
|
||||
|
||||
- do you notify yourself on mattermost/slack ?
|
||||
- do you push the signal to a database so that your blockers can stop the IP from continuing its attack ?
|
||||
- do you want to avoid pushing this signal to the API ?
|
||||
|
||||
Behind the scenes, the "profiles" system actually allows you to dispatch an event/overflow to various output plugins.
|
||||
|
||||
You can find details on the configuration file format of {{ref.output}}.
|
||||
|
||||
## parsers/
|
||||
|
||||
This directory holds all the {{parsers.htmlname}} that are enabled on your system.
|
||||
|
||||
The parsers are organized in {{stages.htmlname}} (which are just folders) and the {{parsers.htmlname}} themselves are yaml files.
|
||||
|
||||
|
||||
## scenarios/
|
||||
|
||||
This directory holds all the {{scenarios.htmlname}} that are enabled on your system.
|
||||
|
||||
The {{scenarios.htmlname}} are yaml files.

## Installing parsers
|
||||
|
||||
### From the hub
|
||||
|
||||
[{{hub.name}}]({{hub.parsers_url}}) allows you to find needed scenarios, just paste the command on your machine :
|
||||
|
||||
|
||||
|
||||
```bash
|
||||
# {{cli.name}} install parser crowdsec/nginx-logs
|

```
|
||||
|
||||
### Your own parsers
|
||||
|
||||
[Write your parser configuration](/write_configurations/parsers/) and deploy yaml file in `{{config.crowdsec_dir}}parsers/<STAGE>/`.
|
||||
|
||||
|
||||
|
||||
## Monitoring parsers behavior
|
||||
|
||||
{{cli.name}} allows you to view {{crowdsec.name}} metrics info via the `metrics` command.
|
||||
This allows you to see how many logs were ingested and then parsed or unparsed by said parser.
|
||||
|
||||
You can see those metrics with the following command:
|
||||
```
|
||||
cscli metrics

Scenarios are yaml files that define "buckets".
|
||||
Most of the scenarios currently rely on the [leaky bucket](https://en.wikipedia.org/wiki/Leaky_bucket) concept.
|
||||
Scenarios lead to the instantiation, and sometime the overflow, of buckets.
|
||||
|
||||
|
||||
When a bucket "overflows", the scenario is considered as having been realized.
|
||||
This event leads to the creation of a new {{event.htmlname}} that describes the scenario that just happened (via a {{signal.htmlname}}).
|
||||
|
||||
|
||||
## Listing installed scenarios
|
||||
|
||||
scenarios are yaml files in `{{config.crowdsec_dir}}scenarios/<scenario>.yaml`.

||||
[{{hub.name}}]({{hub.scenarios_url}}) allows you to find needed scenarios, just paste the command on your machine :
|
||||
|
||||
|

|
||||
### Your own scenarios
|
||||
|
||||
[Write your scenario configuration](/write_configurations/scenarios/) and deploy yaml file in `{{config.crowdsec_dir}}scenarios/<scenario.yaml>`.
|
||||
|
||||
|
||||
|
||||
|
||||
## Monitoring scenarios behavior
|
||||
|
||||
{{cli.name}} allows you to view {{crowdsec.name}} metrics info via the `metrics` command.
|
||||
This allows you to see how many "buckets" associated to each scenario have been created (an event eligible from said scenario has arrived), poured (how many subsequent events have been pushed to said bucket), overflowed (the scenario happened) or underflow (there was not enough event to make the bucket overflow, and it thus expired after a while).
|
||||
|
||||
You can see those metrics with the following command:
|
||||
```
|
||||
{{cli.bin}} metrics
|
||||
```

`{{cli.bin}}` is the utility that will help you to manage {{crowdsec.name}}. This tools has the following functionalities:
|
||||
|
||||
- [manage bans]({{ cli.ban_doc }}) : list, add, remove ...
|
||||
- [backup and restore]({{ cli.backup_doc }}) configuration
|
||||
- [display metrics]({{ cli.metrics_doc }})
|
||||
- [install]({{ cli.install_doc }}) parsers/scenarios/collections
|
||||
- [remove]({{ cli.remove_doc }}) parsers/scenarios/collections
|
||||
- [update]({{ cli.update_doc }}) the hub cache
|
||||
- [upgrade]({{ cli.upgrade_doc }}) parsers/scenarios/collections
|
||||
- [list]({{ cli.list_doc }}) parsers/scenarios/collections
|
||||
- [interact with CrowdSec API]({{ cli.api_doc }})
|
||||
|
||||
## Overview
|
||||
|
||||
{{cli.name}} configuration location is `/etc/crowdsec/cscli/`.
|
||||
|
||||
In this folder, we store the {{cli.name}} configuration and the hub cache files.
|
||||
|
||||
## Config
|
||||
|
||||
The {{cli.name}} configuration is light for now, stored in `/etc/crowdsec/cscli/config`.
|
||||
|
||||
```yaml
|
||||
installdir: /etc/crowdsec/config # {{crowdsec.name}} configuration location
|
||||
backend: /etc/crowdsec/plugins/backend # path to the backend plugin used
|
||||
```
|
||||
|
||||
For {{cli.name}} to be able to pull the {{api.topX.htmlname}}, you need a valid API configuration in [api.yaml](/guide/crowdsec/overview/#apiyaml).
|
||||
|
||||
|
||||
## Hub cache
|
||||
|
||||
- `.index.json`: The file containing the metadata of all the existing {{collections.htmlname}}, {{parsers.htmlname}} and {{scenarios.htmlname}} stored in the {{hub.htmlname}}.
|
||||
- `hub/*`: Folder containing all the {{collections.htmlname}}, {{parsers.htmlname}} and {{scenarios.htmlname}} stored in the {{hub.htmlname}}.
|
||||
|
||||
This is used to manage configurations from the {{cli.name}}

When talking about {{crowdsec.name}} or {{cli.name}} configurations, most of things are going to gravitate around {{parsers.htmlname}}, {{scenarios.htmlname}} and {{collections.htmlname}}.
|
||||
|
||||
In most common setup, all these configurations should be found on the {{hub.htmlname}} and installed with {{cli.name}}.
|
||||
|
||||
It is important to keep those configurations up-to-date via the `{{cli.name}} upgrade` command.
|
||||
|
||||
See the [{{cli.name}} list](/cheat_sheets/cscli-collections-tour/) command to view the state of your deployed configurations.

# What is {{crowdsec.Name}} ?
|
||||
|
||||
{{crowdsec.Name}} is an open-source and lightweight software, that reads logs from different sources (files, streams ...) to parse, normalize and enrich them before comparing them to scenarios.
|
||||
|
||||
Scenarios describe more or less specific attacks, ultimately allowing to report malevolent actors and take further action, such as blocking, reporting, throttling etc.
|
||||
|
||||
One of the advantages of {{crowdsec.name}} when compared to other solutions is its crowded aspect : Meta information about detected attacks (source IP, time and triggered scenario) are sent to a central API and then shared amongst all users.
|
||||
|
||||
Besides detecting and stopping attacks in real time based on your logs, it allows you to preemptively block known malevolent actors from accessing your information system.
|
||||
|
||||
## Components
|
||||
|
||||
{{crowdsec.name}} ecosystem is based on the following tools :
|
||||
|
||||
- {{crowdsec.name}} is the "service" that runs in the background, processes logs and keeps track of attacks
|
||||
- [{{cli.name}}]({{cli.main_doc}}) is the command line interface for humans, it allows you to view, add, or remove bans as well as to install, find ,or update scenarios and parsers
|
||||
- [{{plugins.name}}]({{hub.plugins_url}}) are the components that block malevolent traffic, and can be deployed anywhere in your stack
|
||||
|
||||
## Architecture
|
||||
|
||||
|
||||
|
||||
## Moving forward
|
||||
|
||||

As the default database is sqlite, we use [metabase](https://www.metabase.com/) to visualize the data stored in it.
|
||||
|
||||
The {{cli.name}} command `{{cli.bin}} dashboard setup` will use docker to install [metabase docker image](https://hub.docker.com/r/metabase/metabase/) and fetch our metabase template to have a configured and ready dashboard.

Logs concern everything that happens to {{crowdsec.Name}} itself (startup, configuration, events like IP ban or an alert, shutdown, and so on).
|
||||
|
||||
By default, logs are written to `{{crowdsec.main_log}}`, in text format.

## metrics via {{cli.name}}
|
||||
|
||||
```bash
|
||||
{{cli.name}} metrics
|
||||
```
|
||||
|
||||
This command provides an overview of {{crowdsec.name}} statistics. By default it assumes that the {{crowdsec.name}} is installed on the same machine.
|
||||
|
||||
The metrics are split in 3 main sections :
|
||||
|
||||
- Acquisition metrics : How many lines were read from which sources, how many were successfully or unsuccessfully parsed, and how many of those lines ultimately ended up being poured to a bucket.
|
||||
- Parser metrics : How many lines were fed (eligible) to each parser, and how many of those were successfully or unsuccessfully parsed.
|
||||
- Bucket metrics : How many time each scenario lead to a bucket instantiation, and for each of those :
|
||||
- how many times it overflowed
|
||||
- how many times it expired (underflows)
|
||||
- how many subsequent events were poured to said bucket
|
||||
|
||||
!!! hint
|
||||
These metrics should help you identify potential configuration errors.
|
||||
|
||||
For example, if you have a source that has mostly unparsed logs, you know you might be missing some parsers.
|
||||
As well, if you have scenarios that are never instantiated, it might be a hint that they are not relevant to your configuration.

## metrics via {{crowdsec.name}} prometheus
|
||||
|
||||
{{crowdsec.name}} can expose a prometheus endpoint for collection (on `http://127.0.0.1:6060/metrics` by default).
|
||||
|
||||
The goal of this endpoint, besides the usual resources consumption monitoring, aims at offering a view of {{crowdsec.name}} "applicative" behavior :
|
||||
|
||||
- is it processing a lot of logs ? is it parsing them successfully ?
|
||||
- are a lot of scenarios being triggered ?
|
||||
- are a lot of IPs banned ?
|
||||
- etc.
|
||||
|
||||
All the counters are "since {{crowdsec.name}} start".
|
||||
|
||||
### Scenarios
|
||||
|
||||
- `cs_bucket_create` : number of instantiation of each scenario
|
||||
- `cs_bucket_overflow` : number of overflow of each scenario
|
||||
- `cs_bucket_underflow` : number of underflow of each scenario (bucket was created but expired because of lack of events)
|
||||
- `cs_bucket_pour` : number of event poured to each scenario with source as complementary key :
|
||||
|
||||
```
|
||||
#2030 lines from `/var/log/nginx/access.log` were poured to `crowdsecurity/http-scan-uniques_404` scenario
|
||||
cs_bucket_pour{name="crowdsecurity/http-scan-uniques_404",source="/var/log/nginx/access.log"} 2030
|
||||
```
|
||||
|
||||
|
||||
### Parsers
|
||||
- `cs_node_hits` : how many time an event from a specific source was processed by a parser node :
|
||||
|
||||
```
|
||||
# 235 lines from `auth.log` were processed by the `crowdsecurity/dateparse-enrich` parser
|
||||
cs_node_hits{name="crowdsecurity/dateparse-enrich",source="/var/log/auth.log"} 235
|
||||
```
|
||||
|
||||
- `cs_node_hits_ko` : how many times an event from a specific was unsuccessfully parsed by a specific parser
|
||||
|
||||
```
|
||||
# 2112 lines from `error.log` failed to be parsed by `crowdsecurity/http-logs`
|
||||
cs_node_hits_ko{name="crowdsecurity/http-logs",source="/var/log/nginx/error.log"} 2112
|
||||
```
|
||||
|
||||
- `cs_node_hits_ok` : how many times an event from a specific source was successfully parsed by a specific parser
|
||||
|
||||
- `cs_parser_hits` : how many times an event from a source has hit the parser
|
||||
- `cs_parser_hits_ok` : how many times an event from a source was successfully parsed
|
||||
- `cs_parser_hits_ko` : how many times an event from a source was unsuccessfully parsed
|
||||
|
||||
|
||||
### Acquisition
|
||||
|
||||
- `cs_reader_hits` : how many events were read from a specific source

# Observability Overview
|
||||
|
||||
Observability in security software is crucial, especially when this software might take important decision such as blocking IP addresses.
|
||||
|
||||
We attempt to provide good observability of {{crowdsec.name}}'s behavior :
|
||||
|
||||
- {{crowdsec.name}} itself exposes a prometheus instrumentation
|
||||
- {{cli.Name}} allows you to view part of prometheus metrics in cli (`{{cli.bin}} metrics`)
|
||||
- {{crowdsec.name}} logging is contextualized for easy processing
|
||||
- for **humans**, {{cli.name}} allows you to trivially start a service exposing dashboards (using [metabase](https://www.metabase.com/))
|
||||
|
||||
Furthermore, most of {{crowdsec.name}} configuration should allow you to enable partial debug (ie. per-scenario, per-parser etc.)

# Output
|
||||
|
||||
The output mechanism is composed of plugins. In order to store the bans for {{blockers.htmlname}}, at least one backend plugin must be loaded. Else, bans will not be stored and decisions cannot be applied.
|
||||
|
||||
Please see [here](https://github.com/crowdsecurity/crowdsec/tree/master/plugins/backend) for the available backend plugin.
|
||||
|
||||
In order to filter which signals will be sent to which plugin, {{crowdsec.name}} use a system of `profile` that can allow to granularly process your bans and signals.
|
||||
|
||||
## Profile
|
||||
|
||||
Here is a sample of a profile configuration:
|
||||
|
||||
```yaml
|
||||
profile: <profile_name>
|
||||
filter: "<filter_expression>"
|
||||
api: true # default true : send signal to crowdsec API
|
||||
outputs: # here choose your output plugins for this profile
|
||||
- plugin: plugin1
|
||||
custom_config: <config>
|
||||
- plugin: plugin2
|
||||
|
||||
```
|
||||
|
||||
The default configuration that is deployed with {{crowdsec.name}} is the following one:
|
||||
```yaml
|
||||
profile: default_remediation
|
||||
filter: "sig.Labels.remediation == 'true'"
|
||||
api: true # If no api: specified, will use the default config in default.yaml
|
||||
remediation:
|
||||
ban: true
|
||||
slow: true
|
||||
captcha: true
|
||||
duration: 4h
|
||||
outputs:
|
||||
- plugin: sqlite
|
||||
---
|
||||
profile: default_notification
|
||||
filter: "sig.Labels.remediation != 'true'"
|
||||
#remediation is empty, it means non taken
|
||||
api: false
|
||||
outputs:
|
||||
- plugin: sqlite # If we do not want to push, we can remove this line and the next one
|
||||
store: false
|
||||
```
|
||||
|
||||
Here we can use {{filter.htmlname}} like in parsers and scenarios with the {{signal.htmlname}} object to choose which signal will be process by which plugin.
|
||||
|
||||
## Plugins
|
||||
|
||||
Plugins configuration file are stored in `{{plugins.configpath}}`. {{crowdsec.name}} will scan this folder to load all the plugins. Each configuration file should provide the path to the plugin binary. By default they are stored in `{{plugins.binpath}}`.
|
||||
|
||||
!!! info
|
||||
If you want crowdsec to not load a plugin, `mv` or `rm` its configuration file in `{{plugins.configpath}}`
|
||||
|
||||
Here is a sample of a plugin configuration file stored in `{{plugins.configpath}}`:
|
||||
```yaml
|
||||
name: <plugin_name>
|
||||
path: <path_to_plugin_binary> #
|
||||
config: <plugin_config> # in a form of key(string)/value(string)
|
||||
```
|
||||
|
||||
For the plugin sqlite, here is its configuration file:
|
||||
```yaml
|
||||
name: sqlite
|
||||
path: /var/lib/crowdsec/plugins/backend/sqlite.so
|
||||
config:
|
||||
db_path: /var/lib/crowdsec/data/crowdsec.db
|
||||
flush: true
|
||||
```

## Understanding parsers
|
||||
|
||||
|
||||
Parsers are configurations that define a transformation on an {{event.htmlname}}.
|
||||
Parsers are expressed as YAML files composed of one or more individual 'parsing' nodes.
|
||||
An {{event.htmlname}} can be the representation of a log line, or an overflow.
|
||||
|
||||
A parser itself can be used to perform various actions, including :
|
||||
|
||||
- Parse a string with regular expression (grok patterns)
|
||||
- Enrich an event by relying on "external" code (such as the geoip-enrichment parser)
|
||||
- Process one or more fields of an {{event.name}} with {{expr.htmlname}}
|
||||
|
||||
|
||||
A parser node might look like :
|
||||
```yaml
|
||||
#if 'onsuccess' is 'next_stage', the event will make it to next stage if this node succeed
|
||||
onsuccess: next_stage
|
||||
#a 'debug' (bool) flag allow to enable node level debug in any node to enable local debug
|
||||
debug: true
|
||||
#a filter to decide if the Event is elligible for this parser node
|
||||
filter: "evt.Parsed.program == 'kernel'"
|
||||
#a unique name to allow easy debug & logging
|
||||
name: crowdsecurity/demo-iptables
|
||||
#this is for humans
|
||||
description: "Parse iptables drop logs"
|
||||
#we can define named capture groups (a-la-grok)
|
||||
pattern_syntax:
|
||||
MYCAP: ".*"
|
||||
#an actual grok pattern (regular expression with named capture groupe)
|
||||
grok:
|
||||
pattern: ^xxheader %{MYCAP:extracted_value} trailing stuff$
|
||||
#we define on which field the regular expression must be applied
|
||||
apply_on: evt.Parsed.some_field
|
||||
#statics are transformations that are applied on the event if the node is considered "successfull"
|
||||
statics:
|
||||
#to which field the value will be written (here -> evt.Meta.log_type)
|
||||
- meta: log_type
|
||||
#and here a static value
|
||||
value: parsed_testlog
|
||||
#another one
|
||||
- meta: source_ip
|
||||
#here the value stored is the result of a dynamic expression
|
||||
expression: "evt.Parsed.src_ip"
|
||||
```
|
||||
|
||||
|
||||
The parser nodes are processed sequentially based on the alphabetical order of {{stages.htmlname}} and subsequent files.
|
||||
If the node is considered successful (grok is present and returned data or no grok is present) and "onsuccess" equals to `next_stage`, then the {{event.name}} is moved to the next stage.
|
||||
|
||||
|
||||
## Parser trees
|
||||
|
||||
A parser node can contain sub-nodes, to provide proper branching.
|
||||
It can be useful when you want to apply different parsing based on different criterias, or when you have a set of candidates parsers that you want to apply to an event :
|
||||
|
||||
```yaml
|
||||
#This first node will capture/extract some value
|
||||
filter: "evt.Line.Labels.type == 'type1'"
|
||||
name: tests/base-grok-root
|
||||
pattern_syntax:
|
||||
MYCAP: ".*"
|
||||
grok:
|
||||
pattern: ^... %{MYCAP:extracted_value} ...$
|
||||
apply_on: Line.Raw
|
||||
statics:
|
||||
- meta: state
|
||||
value: root-done
|
||||
- meta: state_sub
|
||||
expression: evt.Parsed.extracted_value
|
||||
---
|
||||
#and this node will apply different patterns to it
|
||||
filter: "evt.Line.Labels.type == 'type1' && evt.Meta.state == 'root-done'"
|
||||
name: tests/base-grok-leafs
|
||||
onsuccess: next_stage
|
||||
#the sub-nodes will process the result of the master node
|
||||
nodes:
|
||||
- filter: "evt.Parsed.extracted_value == 'VALUE1'"
|
||||
debug: true
|
||||
statics:
|
||||
- meta: final_state
|
||||
value: leaf1
|
||||
- filter: "evt.Parsed.extracted_value == 'VALUE2'"
|
||||
debug: true
|
||||
statics:
|
||||
- meta: final_state
|
||||
value: leaf2
|
||||
```
|
||||
|
||||
The logic is that the `tests/base-grok-root` node will be processed first and will alter the event (here mostly by extracting some text from the `Line.Raw` field into `Parsed` thanks to the `grok` pattern and the `statics` directive).
|
||||
|
||||
The event will then continue its life and be parsed by the the following `tests/base-grok-leafs` node.
|
||||
This node has `onsuccess` set to `next_stage` which means that if the node is successful, the event will be moved to the next stage.
|
||||
|
||||
This node consists actually of two sub-nodes that have different conditions (branching) to allow differential treatment of said event.
|
||||
|
||||
A real-life example can be seen when it comes to parsing HTTP logs.
|
||||
HTTP ACCESS and ERROR logs often have different formats, and thus our "nginx" parser needs to handle both formats
|
||||
|
||||
```yaml
|
||||
filter: "evt.Parsed.program == 'nginx'"
|
||||
onsuccess: next_stage
|
||||
name: crowdsecurity/nginx-logs
|
||||
nodes:
|
||||
- grok:
|
||||
#this is the access log
|
||||
name: NGINXACCESS
|
||||
apply_on: message
|
||||
statics:
|
||||
- meta: log_type
|
||||
value: http_access-log
|
||||
- target: evt.StrTime
|
||||
expression: evt.Parsed.time_local
|
||||
- grok:
|
||||
# and this one the error log
|
||||
name: NGINXERROR
|
||||
apply_on: message
|
||||
statics:
|
||||
- meta: log_type
|
||||
value: http_error-log
|
||||
- target: evt.StrTime
|
||||
expression: evt.Parsed.time
|
||||
# these ones apply for both grok patterns
|
||||
statics:
|
||||
- meta: service
|
||||
value: http
|
||||
- meta: source_ip
|
||||
expression: "evt.Parsed.remote_addr"
|
||||
- meta: http_status
|
||||
expression: "evt.Parsed.status"
|
||||
- meta: http_path
|
||||
expression: "evt.Parsed.request"
|
||||
```
|
||||
|
||||
## Parser directives
|
||||
|
||||
### debug
|
||||
|
||||
```yaml
|
||||
debug: true|false
|
||||
```
|
||||
_default: false_
|
||||
|
||||
If set to to `true`, enabled node level debugging.
|
||||
It is meant to help understanding parser node behaviour by providing contextual logging.
|
||||
|
||||
|
||||
### filter
|
||||
|
||||
```yaml
|
||||
filter: expression
|
||||
```
|
||||
|
||||
`filter` must be a valid {{expr.htmlname}} expression that will be evaluated against the {{event.name}}.
|
||||
If `filter` evaluation returns true or is absent, node will be processed.
|
||||
If `filter` returns `false` or a non-boolean, node won't be processed.
|
||||
|
||||
Examples :
|
||||
|
||||
- `filter: "evt.Meta.foo == 'test'"`
|
||||
- `filter: "evt.Meta.bar == 'test' && evt.Meta.foo == 'test2'`
|
||||
|
||||
|
||||
### grok
|
||||
|
||||
```yaml
|
||||
grok:
|
||||
name: NAMED_EXISTING_PATTERN
|
||||
apply_on: source_field
|
||||
```
|
||||
|
||||
```yaml
|
||||
grok:
|
||||
pattern: ^a valid RE2 expression with %{CAPTURE:field}$
|
||||
apply_on: source_field
|
||||
```
|
||||
|
||||
The `grok` structure in a node represent a regular expression with capture group (grok pattern) that must be applied on a field of {{event.name}}.
|
||||
|
||||
The pattern can :
|
||||
|
||||
- be imported by name (if present within the core of {{crowdsec.name}})
|
||||
- defined in place
|
||||
|
||||
In both case, the pattern must be a valid RE2 expression.
|
||||
The field(s) returned by the regular expression are going to be merged into the `Parsed` associative array of the `Event`.
|
||||
|
||||
|
||||
|
||||
### name
|
||||
|
||||
```yaml
|
||||
name: explicit_string
|
||||
```
|
||||
|
||||
The *mandatory* name of the node. If not present, node will be skipped at runtime.
|
||||
It is used for example in debug log to help you track things.
|
||||
|
||||
### nodes
|
||||
|
||||
```yaml
|
||||
nodes:
|
||||
- filter: ...
|
||||
grok: ...
|
||||
```
|
||||
|
||||
`nodes` is a list of parser nodes, allowing you to build trees.
|
||||
Each subnode must be valid, and if any of the subnodes succeed, the whole node is considered successful.
|
||||
|
||||
### onsuccess
|
||||
|
||||
```
|
||||
onsuccess: next_stage|continue
|
||||
```
|
||||
|
||||
_default: continue_
|
||||
|
||||
if set to `next_stage` and the node is considered successful, the {{event.name}} will be moved directly to next stage without processing other nodes in the current stage.
|
||||
|
||||
### pattern_syntax
|
||||
|
||||
```yaml
|
||||
pattern_syntax:
|
||||
CAPTURE_NAME: VALID_RE2_EXPRESSION
|
||||
```
|
||||
|
||||
`pattern_syntax` allows user to define named capture group expressions for future use in grok patterns.
|
||||
Regexp must be a valid RE2 expression.
|
||||
|
||||
```yaml
|
||||
pattern_syntax:
|
||||
MYCAP: ".*"
|
||||
grok:
|
||||
pattern: ^xxheader %{MYCAP:extracted_value} trailing stuff$
|
||||
apply_on: Line.Raw
|
||||
```
|
||||
|
||||
|
||||
### statics
|
||||
|
||||
```yaml
|
||||
statics:
|
||||
- target: evt.Meta.target_field
|
||||
value: static_value
|
||||
- meta: target_field
|
||||
expression: evt.Meta.target_field + ' this_is' + ' a dynamic expression'
|
||||
- enriched: target_field
|
||||
value: static_value
|
||||
```
|
||||
|
||||
`statics` is a list of directives that will be executed when the node is considered successful.
|
||||
Each entry of the list is composed of a target (where to write) and a source (what data to write).
|
||||
|
||||
**Target**
|
||||
|
||||
The target aims at being any part of the {{event.htmlname}} object, and can be expressed in different ways :
|
||||
|
||||
- `meta: <target_field>`
|
||||
- `parsed: <target_field>`
|
||||
- `enriched: <target_field>`
|
||||
- a dynamic target (please note that the **current** event is accessible via the `evt.` variable) :
|
||||
- `target: evt.Meta.foobar`
|
||||
- `target: Meta.foobar`
|
||||
- `target: evt.StrTime`
|
||||
|
||||
|
||||
**Source**
|
||||
|
||||
The source itself can be either a static value, or an {{expr.htmlname}} result :
|
||||
|
||||
```yaml
|
||||
statics:
|
||||
- meta: target_field
|
||||
value: static_value
|
||||
- meta: target_field
|
||||
expression: evt.Meta.another_field
|
||||
- meta: target_field
|
||||
expression: evt.Meta.target_field + ' this_is' + ' a dynamic expression'
|
||||
```
|
||||
|
||||
|
||||
## Parser concepts
|
||||
|
||||
|
||||
### Success and failure
|
||||
|
||||
A parser is considered "successful" if :
|
||||
- A grok pattern was present and successfully matched
|
||||
- No grok pattern was present

## Understanding scenarios
|
||||
|
||||
|
||||
Scenarios are YAML files that allow to detect and qualify a specific behavior, usually an attack.
|
||||
|
||||
Scenarios receive one or more {{event.htmlname}} and might produce one or more {{overflow.htmlname}}.
|
||||
As an {{event.htmlname}} can be the representation of a log line, or an overflow, it allows scenarios to process both logs or overflows.
|
||||
|
||||
|
||||
The scenario is usually based on a number of factors, at least :
|
||||
|
||||
- the speed/frequency at which events happen (see [leaky bucket](https://en.wikipedia.org/wiki/Leaky_bucket))
|
||||
- the characteristic(s) of an {{event.htmlname}} : "log type XX with field YY set to ZZ"
|
||||
|
||||
|
||||
|
||||
Behind the scenes, {{crowdsec.name}} is going to create one or several buckets when event with matching characteristic arrive to the scenario. This bucket has a capacity and leak-speed, when the bucket "overflows", the scenario has been trigger.
|
||||
|
||||
_Bucket partitioning_ : One scenario usually leads to many bucket creation, as each bucket is only tracking a specific subset of events. For example, if we are tracking brute-force, it makes sense that each "offending peer" get its own bucket.
|
||||
|
||||
|
||||
A way to detect a http scanner might be to track the number of distinct non-existing pages it's requesting, and the scenario might look like this :
|
||||
|
||||
|
||||
```yaml
|
||||
#the bucket type : leaky, trigger, counter
|
||||
type: leaky
|
||||
#name and description for humans
|
||||
name: crowdsecurity/http-scan-uniques_404
|
||||
description: "Detect multiple unique 404 from a single ip"
|
||||
#a filter to know which events are eligible
|
||||
filter: "evt.Meta.service == 'http' && evt.Meta.http_status in ['404', '403', '400']"
|
||||
#how we are going to partition buckets
|
||||
groupby: "evt.Meta.source_ip"
|
||||
#we are only interested into counting UNIQUE/DISTINCT requested URLs
|
||||
distinct: "evt.Meta.http_path"
|
||||
#we specify the bucket capacity and leak speed
|
||||
capacity: 5
|
||||
leakspeed: "10s"
|
||||
#this will prevent the same bucket from overflowing more often than every 5 minutes
|
||||
blackhole: 5m
|
||||
#some labels to give context to the overflow
|
||||
labels:
|
||||
service: http
|
||||
type: scan
|
||||
#yes we want to ban people triggering this
|
||||
remediation: true
|
||||
```
|
||||
|
||||
|
||||
## Scenario concepts
|
||||
|
||||
### TimeMachine
|
||||
|
||||
{{crowdsec.name}} can be used not only to process live logs, but as well to process "cold" logs (think forensics).
|
||||
|
||||
For this to be able to work, the date/time from the log must have been properly parsed for the scenario temporal aspect to be able to work properly. This relies on the [dateparser enrichment](https://github.com/crowdsecurity/hub/blob/master/parsers/s02-enrich/crowdsecurity/dateparse-enrich.yaml)
|
||||
|
||||
|
||||
## Scenario directives
|
||||
|
||||
### type
|
||||
|
||||
|
||||
```yaml
|
||||
type: leaky|trigger|counter
|
||||
```
|
||||
|
||||
Defines the type of the bucket. Currently three types are supported :
|
||||
|
||||
- `leaky` : a [leaky bucket](https://en.wikipedia.org/wiki/Leaky_bucket) that must be configured with a {{capacity.htmlname}} and a {{leakspeed.htmlname}}
|
||||
- `trigger` : a bucket that overflows as soon as an event is poured (it's like a leaky bucket is a capacity of 0)
|
||||
- `counter` : a bucket that only overflows every {{duration.htmlname}}. It's especially useful to count things.
|
||||
|
||||
### name & description
|
||||
|
||||
```yaml
|
||||
name: my_author_name/my_scenario_name
|
||||
description: A scenario that detect XXXX behavior
|
||||
```
|
||||
|
||||
|
||||
Mandatory `name` and `description` for said scenario.
|
||||
The name must be unique (and will define the scenario's name in the hub), and the description must be a quick sentence describing what it detects.
|
||||
|
||||
|
||||
### filter
|
||||
|
||||
```yaml
|
||||
filter: evt.Meta.log_type == 'telnet_new_session'
|
||||
```
|
||||
|
||||
|
||||
an {{expr.htmlname}} that must return true if the event is eligible for the bucket.
|
||||
|
||||
|
||||
Examples :
|
||||
|
||||
- `evt.Meta.log_type == 'telnet_new_session'`
|
||||
- `evt.Meta.log_type in ['http_access-log', 'http_error-log'] && evt.Parsed.static_ressource == 'false'`
|
||||
- `evt.Meta.log_type == 'ssh_failed-auth'`
|
||||
|
||||
|
||||
### duration
|
||||
|
||||
```yaml
|
||||
duration: 45s
|
||||
duration: 10m
|
||||
```
|
||||
|
||||
(applicable to `counter` buckets only)
|
||||
|
||||
A duration after which the bucket will overflow.
|
||||
The format must be compatible with [golang ParseDuration format](https://golang.org/pkg/time/#ParseDuration)
|
||||
|
||||
Examples :
|
||||
|
||||
```yaml
|
||||
type: counter
|
||||
name: crowdsecurity/ban-reports-ssh_bf_report
|
||||
description: "Count unique ips performing ssh bruteforce"
|
||||
filter: "evt.Overflow.Scenario == 'ssh_bruteforce'"
|
||||
distinct: "evt.Overflow.Source_ip"
|
||||
capacity: -1
|
||||
duration: 10m
|
||||
labels:
|
||||
service: ssh
|
||||
```
|
||||
|
||||
|
||||
### groupby
|
||||
|
||||
```yaml
|
||||
groupby: evt.Meta.source_ip
|
||||
```
|
||||
|
||||
|
||||
an {{expr.htmlname}} that must return a string. This string will be used as to partition the buckets.
|
||||
|
||||
|
||||
Examples :
|
||||
|
||||
Here, each `source_ip` will get its own bucket.
|
||||
|
||||
```yaml
|
||||
type: leaky
|
||||
...
|
||||
groupby: evt.Meta.source_ip
|
||||
...
|
||||
```
|
||||
|
||||
|
||||
|
||||
Here, each unique combo of `source_ip` + `target_username` will get its own bucket.
|
||||
|
||||
```yaml
|
||||
type: leaky
|
||||
...
|
||||
groupby: evt.Meta.source_ip + '--' + evt.Parsed.target_username
|
||||
...
|
||||
```
|
||||
|
||||
|
||||
|
||||
### distinct
|
||||
|
||||
|
||||
```yaml
|
||||
distinct: evt.Meta.http_path
|
||||
```
|
||||
|
||||
|
||||
an {{expr.htmlname}} that must return a string. The event will be poured **only** if the string is not already present in the bucket.
|
||||
|
||||
Examples :
|
||||
|
||||
This will ensure that events that keep triggering the same `.Meta.http_path` will be poured only once.
|
||||
|
||||
```yaml
|
||||
type: leaky
|
||||
...
|
||||
distinct: "evt.Meta.http_path"
|
||||
...
|
||||
```
|
||||
|
||||
In the logs, you can see it like this (for example from the iptables-logs portscan detection) :
|
||||
|
||||
```bash
|
||||
DEBU[2020-05-13T11:29:51+02:00] Uniq(7681) : ok buck..
|
||||
DEBU[2020-05-13T11:29:51+02:00] Uniq(7681) : ko, discard event buck..
|
||||
```
|
||||
|
||||
The first event has been poured (value `7681`) was not yet present in the events, while the second time, the event got discarded because the value was already present in the bucket.
|
||||
|
||||
|
||||
### capacity
|
||||
|
||||
```yaml
|
||||
capacity: 5
|
||||
```
|
||||
|
||||
|
||||
(Applies only to `leaky` buckets)
|
||||
|
||||
A positive integer representing the bucket capacity.
|
||||
If there are more than `capacity` item in the bucket, it will overflow.
|
||||
|
||||
|
||||
### leakspeed
|
||||
|
||||
```yaml
|
||||
leakspeed: "10s"
|
||||
```
|
||||
|
||||
(Applies only to `leaky` buckets)
|
||||
|
||||
A duration that represent how often an event will be leaking from the bucket.
|
||||
|
||||
Must be compatible with [golang ParseDuration format](https://golang.org/pkg/time/#ParseDuration).
|
||||
|
||||
|
||||
Example:
|
||||
|
||||
Here the bucket will leak one item every 10 seconds, and can hold up to 5 items before overflowing.
|
||||
|
||||
```yaml
|
||||
type: leaky
|
||||
...
|
||||
leakspeed: "10s"
|
||||
capacity: 5
|
||||
...
|
||||
```
|
||||
|
||||
|
||||
### labels
|
||||
|
||||
```yaml
|
||||
labels:
|
||||
service: ssh
|
||||
type: bruteforce
|
||||
remediation: true
|
||||
```
|
||||
|
||||
Labels is a list of `label: values` that provide context to an overflow.
|
||||
The labels are (currently) not stored in the database, nor they are sent to the API.
|
||||
|
||||
Special labels :
|
||||
|
||||
- The **remediation** label, if set to `true` indicate the the originating IP should be ban.
|
||||
- The **scope** label, can be set to `ip` or `range` when **remediation** is set to true, and indicate to which scope should the decision apply. If you set a scenario with **remediation** to true and **scope** to `range` and the range of the IP could have been determined by the GeoIP library, the whole range to which the IP belongs will be banned.
|
||||
|
||||
|
||||
Example :
|
||||
|
||||
The IP that triggered the overflow (`.Meta.source_ip`) will be banned.
|
||||
```yaml
|
||||
type: leaky
|
||||
...
|
||||
labels:
|
||||
service: ssh
|
||||
type: bruteforce
|
||||
remediation: true
|
||||
```
|
||||
|
||||
The range to which the offending IP belong (`.Meta.source_ip`) will be banned.
|
||||
```yaml
|
||||
type: leaky
|
||||
...
|
||||
labels:
|
||||
type: distributed_attack
|
||||
remediation: true
|
||||
scope: range
|
||||
```
|
||||
|
||||
### blackhole
|
||||
|
||||
```yaml
|
||||
blackhole: 10m
|
||||
```
|
||||
|
||||
A duration for which a bucket will be "silenced" after overflowing.
|
||||
This is intended to limit / avoid spam of buckets that might be very rapidly triggered.
|
||||
|
||||
The blackhole only applies to the individual bucket rather than the whole scenario.
|
||||
|
||||
Must be compatible with [golang ParseDuration format](https://golang.org/pkg/time/#ParseDuration).
|
||||
|
||||
Example :
|
||||
|
||||
The same `source_ip` won't be able to trigger this overflow more than once every 10 minutes.
|
||||
The potential overflows in the meanwhile will be discarded (but will still appear in logs as being blackholed).
|
||||
|
||||
```yaml
|
||||
type: trigger
|
||||
...
|
||||
blackhole: 10m
|
||||
groupby: evt.Meta.source_ip
|
||||
```
|
||||
|
||||
### debug
|
||||
|
||||
```yaml
|
||||
debug: true|false
|
||||
```
|
||||
|
||||
_default: false_
|
||||
|
||||
|
||||
If set to to `true`, enabled scenario level debugging.
|
||||
It is meant to help understanding scenario behavior by providing contextual logging.
|
||||
|
||||
### reprocess
|
||||
|
||||
```yaml
|
||||
reprocess: true|false
|
||||
```
|
||||
|
||||
_default: false_
|
||||
|
||||
If set to `true`, the resulting overflow will be sent again in the scenario/parsing pipeline.
|
||||
It is useful when you want to have further scenarios that will rely on past-overflows to take decisions.
|
||||
|
||||
|
||||
### cache_size
|
||||
|
||||
```yaml
|
||||
cache_size: 5
|
||||
```
|
||||
|
||||
By default, a bucket holds {{capacity.htmlname}} events "in memory".
|
||||
However, for a number of cases, you don't want this, as it might lead to excessive memory consumption.
|
||||
|
||||
By setting `cache_size` to a positive integer, we can control the maximum in-memory cache size of the bucket, without changing its capacity and such. This is especially useful when using `counter` buckets on long duration that might end up counting (and this storing in memory) an important number of events.
|
||||
|
||||
|
||||
### overflow_filter
|
||||
|
||||
```yaml
|
||||
overflow_filter: any(queue.Queue, { .Enriched.IsInEU == "true" })
|
||||
```
|
||||
|
||||
`overflow_filter` is an {{expr.htmlname}} that is run when the bucket overflows.
|
||||
If this expression is present and returns false, the overflow will be discarded.

# Write the acquisition file (optional for test)
|
||||
|
||||
In order for your log to be processed by the good parser, it must match the filter that you will configure in your parser file.
|
||||
There is two option:
|
||||
|
||||
- Your logs are wrote from a syslog server, so you just have to install the [syslog parser](https://master.d3padiiorjhf1k.amplifyapp.com/author/crowdsecurity/configurations/syslog-logs)
|
||||
- You're log are read from a log file. Please add this kind of configuration in your `acquis.yaml` file:
|
||||
|
||||
ⓘ the `prog_name` is the one that the parser in `s01-parse` filter will need to match.
|
||||

# Writing {{crowdsec.Name}} parser
|
||||
|
||||
!!! info
|
||||
Please ensure that you have working env or setup test environment before writing your parser.
|
||||
|
||||
> In the current example, we'll write a parser for the logs produced by `iptables` (netfilter) with the `-j LOG` target.
|
||||
> This document aims at detailing the process of writing and testing new parsers.
|
||||
|
||||
## Base parser file
|
||||
|
||||
The most simple parser can be defined as :
|
||||
|
||||
```yaml
|
||||
filter: 1 == 1
|
||||
debug: true
|
||||
onsuccess: next_stage
|
||||
name: me/myparser
|
||||
description: a cool parser for my service
|
||||
grok:
|
||||
#our grok pattern : capture .*
|
||||
pattern: ^%{DATA:some_data}$
|
||||
#the field to which we apply the grok pattern : the log message itself
|
||||
apply_on: message
|
||||
statics:
|
||||
- parsed: is_my_service
|
||||
value: yes
|
||||
```
|
||||
|
||||
- a {{filter.htmlname}} : if the expression is `true`, the event will enter the parser, otherwise, it won't
|
||||
- a {{onsuccess.htmlname}} : defines what happens when the {{event.htmlname}} was successfully parsed : shall we continue ? shall we move to next stage ? etc.
|
||||
- a name & a description
|
||||
- some {{statics.htmlname}} that will modify the {{event.htmlname}}
|
||||
- a `debug` flag that allows to enable local debugging information.
|
||||
|
||||
|
||||
We are going to use to following sample log as an example :
|
||||
```bash
|
||||
May 11 16:23:43 sd-126005 kernel: [47615895.771900] IN=enp1s0 OUT= MAC=00:08:a2:0c:1f:12:00:c8:8b:e2:d6:87:08:00 SRC=99.99.99.99 DST=127.0.0.1 LEN=40 TOS=0x00 PREC=0x00 TTL=245 ID=51006 PROTO=TCP SPT=45225 DPT=8888 WINDOW=1024 RES=0x00 SYN URGP=0
|
||||

|
||||
```
|
||||
|
||||
## Let's try our mock parser
|
||||
|
||||
!!! warning
|
||||
Your yaml file must be in the `config/parsers/s01-parser/` directory (relative to your current test directory).
|
||||
|
||||
For example it can be `~/crowdsec-v0.0.19/tests/config/parsers/s01-parser/myparser.yaml`
|
||||
|
||||
The stage directory might not exist, don't forget to create it.
|
||||
|
||||
|
||||
Setting up our new parser :
|
||||
```bash
|
||||
cd crowdsec-v0.X.Y/tests
|
||||
```
|
||||
|
||||
```bash
|
||||
mkdir -p config/parsers/s01-parser
|
||||
```
|
||||
```bash
|
||||
cp myparser.yaml config/parsers/s01-parser/
|
||||
```
|
||||
|
||||
Testing our new parser :
|
||||
```bash
|
||||
./crowdsec -c ./dev.yaml -file ./x.log -type foobar
|
||||
```

|
||||
...
|
||||
```
|
||||
</details>
|
||||
|
||||
|
||||
We can see our "mock" parser is working, let's see what happened :
|
||||
|
||||
- The event enter the node
|
||||
- The `filter` returned true (`1 == 1`) so the {{event.htmlname}} will be processed
|
||||
- Our grok pattern (just a `.*` capture) "worked" and captured data (the whole line actually)
|
||||
- The grok captures (under the name "some_data") are merged into the `.Parsed` map of the {{event.htmlname}}
|
||||
- The {{statics.htmlname}} section is processed, and `.Parsed[is_my_service]` is set to `yes`
|
||||
- The {{event.htmlname}} leaves the parser successfully, and because "next_stage" is set, we move the event to the next "stage"
|
||||
|
||||
## Writing the GROK pattern
|
||||
|
||||
We are going to write a parser for `iptables` logs, they look like this :
|
||||
|
||||
```
|
||||
May 11 16:23:43 sd-126005 kernel: [47615895.771900] IN=enp1s0 OUT= MAC=00:08:a2:0c:1f:12:00:c8:8b:e2:d6:87:08:00 SRC=99.99.99.99 DST=127.0.0.1 LEN=40 TOS=0x00 PREC=0x00 TTL=245 ID=51006 PROTO=TCP SPT=45225 DPT=8888 WINDOW=1024 RES=0x00 SYN URGP=0
|
||||
May 11 16:23:50 sd-126005 kernel: [47615902.763137] IN=enp1s0 OUT= MAC=00:08:a2:0c:1f:12:00:c8:8b:e2:d6:87:08:00 SRC=44.44.44.44 DST=127.0.0.1 LEN=60 TOS=0x00 PREC=0x00 TTL=49 ID=17451 DF PROTO=TCP SPT=53668 DPT=80 WINDOW=14600 RES=0x00 SYN URGP=0
|
||||
|
||||
```
|
||||
|
||||
Using an [online grok debugger](https://grokdebug.herokuapp.com/) or an [online regex debugger](https://www.debuggex.com/), we come up with the following grok pattern :
|
||||
|
||||
`\[%{DATA}\]+.*(%{WORD:action})? IN=%{WORD:int_eth} OUT= MAC=%{IP}:%{MAC} SRC=%{IP:src_ip} DST=%{IP:dst_ip} LEN=%{INT:length}.*PROTO=%{WORD:proto} SPT=%{INT:src_port} DPT=%{INT:dst_port}.*`
|
||||
|
||||
!!! warning
|
||||
Check if the pattern you are looking for is not already present in [patterns configuration](https://github.com/crowdsecurity/crowdsec/tree/master/config/patterns).
|
||||
|
||||
|
||||
## Test our new pattern
|
||||
|
||||
Now, let's integrate our GROK pattern within our YAML :
|
||||
|
||||
```yaml
|
||||
#let's set onsuccess to "next_stage" : if the log is parsed, we can consider it has been dealt with
|
||||
onsuccess: next_stage
|
||||
#debug, for reasons (don't do this in production)
|
||||
debug: true
|
||||
#as seen in our sample log, those logs are processed by the system and have a progname set to 'kernel'
|
||||
filter: "1 == 1"

</details>
|
||||
|
||||
What changed ? We can now see that the fragment captured by the GROK pattern are merged in the `Parsed` array !
|
||||
We now have parsed data, only a few more changes and we will be done :)
|
||||
|
||||
## Finalizing our parser
|
||||
|
||||
```yaml
|
||||
#let's set onsuccess to "next_stage" : if the log is parsed, we can consider it has been dealt with
|
||||
onsuccess: next_stage
|
||||
#debug, for reasons (don't do this in production)
|
||||
debug: true
|
||||
#as seen in our sample log, those logs are processed by the system and have a progname set to 'kernel'
|
||||
filter: "evt.Parsed.program == 'kernel'"
|
||||
#name and description:
|
||||
name: crowdsecurity/iptables-logs
|
||||
description: "Parse iptables drop logs"
|
||||
grok:
|
||||
#our grok pattern
|
||||
pattern: \[%{DATA}\]+.*(%{WORD:action})? IN=%{WORD:int_eth} OUT= MAC=%{IP}:%{MAC} SRC=%{IP:src_ip} DST=%{IP:dst_ip} LEN=%{INT:length}.*PROTO=%{WORD:proto} SPT=%{INT:src_port} DPT=%{INT:dst_port}.*
|
||||
#the field to which we apply the grok pattern : the log message itself
|
||||
apply_on: message
|
||||
statics:
|
||||
- meta: log_type
|
||||
value: iptables_drop
|
||||
- meta: service
|
||||
expression: "evt.Parsed.proto == 'TCP' ? 'tcp' : 'unknown'"
|
||||
- meta: source_ip
|
||||
expression: "evt.Parsed.src_ip"
|
||||
```
|
||||
|
||||
### filter
|
||||
|
||||
We changed the {{filter.htmlname}} to correctly filter on the program name.
|
||||
In the current example, our logs are produced by the kernel (netfilter), and thus the program is `kernel` :
|
||||
|
||||
```bash
|
||||
tail -f /var/log/kern.log
|
||||
May 11 16:23:50 sd-126005 kernel: [47615902.763137] IN=enp1s0 OUT= MAC=00:08:a2:0c:1f:12:00:c8:8b:e2:d6:87:08:00 SRC=44.44.44.44 DST=127.0.0.1 LEN=60 TOS=0x00 PREC=0x00 TTL=49 ID=17451 DF PROTO=TCP SPT=53668 DPT=80 WINDOW=14600 RES=0x00 SYN URGP=0
|
||||
```
|
||||
|
||||
### statics
|
||||
|
||||
We are setting various entries to static or dynamic values to give "context" to the log :
|
||||
|
||||
- `.Meta.log_type` is set to `iptables_drop` (so that we later can filter events coming from this)
|
||||
- `.Meta.source_ip` is set the the source ip captured `.Parsed.src_ip`
|
||||
- `.Meta.service` is set the the result of an expression that relies on the GROK output (`proto` field)
|
||||
|
||||
Look into dedicated {{statics.htmlname}} documentation to know more about its possibilities.
|
||||
|
||||
|
||||
### Testing our finalized parser

||||

|

## Closing word
|
||||
|
||||
We have now a fully functional parser for {{crowdsec.name}} !
|
||||
We can either deploy it to our production systems to do stuff, or even better, contribute to the {{hub.htmlname}} !
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
<!--
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
The first field that you will write is the `onsuccess` one. This one indicate what to do in case of success log parsing. Put the value `next_stage` if you want the log to be processed by the next stages in case of parsing success:
|
||||
```yaml
|
||||
onsuccess: next_stage
|
||||
```
|
||||
|
||||
Then come the `filter` part.
|
||||
You will mostly want to filter on the `program` of the event:
|
||||
|
||||
```yaml
|
||||
filter: evt.Parsed.program == '<program>'
|
||||
```
|
||||
|
||||
The `name` (please name your parser like `<github_account_name>/<parser_name>`):
|
||||
|
||||
```yaml
|
||||
name: crowdsecurity/example
|
||||
```
|
||||
|
||||
A small description:
|
||||
|
||||
```yaml
|
||||
description: this parser can process X/Y/Z logs from <program>
|
||||
```
|
||||
|
||||
|
||||
The grok part:
|
||||
|
||||
- If you have only one type of log then you can start with the `grok` object which is defined as below:
|
||||
```yaml
|
||||
grok:
|
||||
pattern: <your_grok_pattern_here> # can't be used with 'name'
|
||||
name: <grok_name> # grok name loaded from https://github.com/crowdsecurity/crowdsec/tree/master/config/patterns. can't be used with 'pattern'
|
||||
apply_on: message
|
||||
statics:
|
||||
- <meta|target> : <field_name>
|
||||
<value|expression> : <field_value>
|
||||
- <meta|target> : <field_name>
|
||||
<value|expression> : <field_value>
|
||||
|
||||
```
|
||||
The grok pattern will be applied on the `message` field of the previous success stage.
|
||||
The `pattern` and `name` keyword can't be use together
|
||||
|
||||
|
||||
- If you have more type of logs, you will have to start with the `node` keyword that is a list of grok:
|
||||
|
||||
```yaml
|
||||
nodes:
|
||||
grok:
|
||||
pattern: <your_first_grok_pattern>
|
||||
apply_on: message
|
||||
statics:
|
||||

|
||||
|
||||
The `statics` is a process that will set up a value for a given key in the parsed event.
|
||||
For the field `name` the keyword can be either `meta` or `target`:
|
||||
|
||||
- `meta` : the new field will be created in the evt.Meta object to be accessible like : `evt.Meta.<new_field>`;
|
||||
```yaml
|
||||
meta: log_type
|
||||
```
|
||||
- `target`: the name of the new field:
|
||||
```yaml
|
||||
target: evt.source_ip
|
||||
```
|
||||
|
||||
For the field value, it can be either `value` or `expression`:
|
||||
|
||||
- `value` is the value assigned, for example : `http_access_log`
|
||||
|
||||
```yaml
|
||||
value: http_access_log
|
||||
```
|
||||
|
||||
- `expression` the result of a parsed field, for example : `evt.Parsed.remote_addr`
|
||||
```yaml
|
||||
expression : evt.Parsed.remote_addr
|
||||
```
|
||||
|
||||
The `statics` can be applied only for the grok it succeed, if it is in the `grok` object, else for whatever grok if at the root level.

# Requirements
|

>Some requirements are needed in order to be able to write your own end-to-end configurations.
|

>During all this documentation, we are going to show as an exemple how we wrote a full port scan detection scenario (from acqusition to scenario, including parser)
|
||||
|
||||
## Create the test environment
|
||||
|
||||
First of all, please [download the latest release of {{crowdsec.name}}](https://github.com/crowdsecurity/crowdsec/releases).
|
||||
|
||||
Then run the following commands:
|
||||
|
||||
```bash
|
||||
tar xzvf crowdsec-release.tgz
|
||||
```
|
||||
```bash
|
||||
cd ./crowdsec-vX.Y/
|
||||
```
|
||||
```bash
|
||||
./test_env.sh # the -o is facultative, default is "./tests/"
|
||||
```
|
||||
```bash
|
||||
cd ./tests/
|
||||
```
|
||||
|
||||
The `./test_env.sh` script creates a local (non privileged) working environement for {{crowdsec.name}} and {{cli.name}}.
|
||||
The deployed environment is intended to write and test parsers and scenarios easily.

## ⓘ Reminder
|
||||
|
||||
Logs parsing is divided into stage. Each stage are called in the format "sXX-<stage_name>". If a log success in a stage and is configured to go in `next_stage`, then the next stage will process it. Stage process is sorted alphabetically.
|
||||
|
||||
Stages and parsers are being processed alphabetically, thus the expected order would be :
|
||||
|
||||
```
|
||||
s00-raw/syslog.yaml
|
||||
|
||||
s01-parse/nginx.yaml
|
||||
s01-parse/apache.yaml
|
||||
|
||||
s02-enrich/geoip.yaml
|
||||
s02-enrich/rdns.yaml
|
||||
```
|
||||
|
||||
### Basics stage
|
||||
|
||||
- The first stage (`s00-parse`) is mostly the one that will parsed the begining of your log to say : "This log come from this `source`" where the source can be whatever software that produce logs.
|
||||
If all your logs are sent to a syslog server, there is a [parser](https://master.d3padiiorjhf1k.amplifyapp.com/author/crowdsecurity/configurations/syslog-logs) that will parse the syslog header to detect the program source.
|
||||
When the log is processed, the results (ie. capture groups) will be merged in the current {{event.htmlname}} before being sent to the next stage.
|
||||
|
||||
- The second (`s01-parse`) is the one that will parse the logs and output parsed data and static assigned values. There is currently one parser for one type of software. To parse the logs, regexp or GROK pattern are used. If the parser is configured to go to the [`next_stage`](/references/parsers/#onsuccess), then it will be process by the `enrichment` stage.
|
||||
|
||||
- The enrichment `s02-enrich` stage is the one that will enrich the normalized log (we call it an event now that it is normalized) in order to get more information for the heuristic process. This stage can be composed of grok patterns and so on, but as well of plugins that can be writen by the community (geiop enrichment, rdns ...)
|
||||
|
||||
### Custom stage
|
||||
|
||||
Of course, it is possible to write custom stages. If you want some specific parsing or enrichment to be done after the `s02-enrich` stage, it is possible by creating a new folder `s03-<custom_stage>`. The configuration that will be created in this folder will process the logs configurated to go to `next_stage` in the `s02-enrich` stage. Be careful to write filter that will match incoming event in your custom stage.

# Writing {{crowdsec.Name}} scenarios
|
||||
|
||||
!!! info
|
||||
Please ensure that you have working env or setup test environment before writing your scenario.
|
||||
|
||||
Ensure that your logs are properly parsed.
|
||||
|
||||
Have some sample logs at hand reach to test your scenario as you progress.
|
||||
|
||||
|
||||
> In the current example, we'll write a scenario to detect port scans relying on the logs produced by `iptables` (netfilter) with the `-j LOG` target.
|
||||
|
||||
> This document aims at detailing the process of writing and testing new scenarios.
|
||||
|
||||
|
||||
## Base scenario file
|
||||
|
||||
|
||||
The simple scenario can be defined as :
|
||||
|
||||
```yaml
|
||||
type: leaky
|
||||
debug: true
|
||||
name: me/my-cool-scenario
|
||||
description: "detect cool stuff"
|
||||
filter: "1 == 1"
|
||||
capacity: 1
|
||||
leakspeed: 1m
|
||||
blackhole: 1m
|
||||
labels:
|
||||
type: my_test
|
||||
```
|
||||
|
||||
- a {{filter.htmlname}} : if the expression is `true`, the event will enter the parser, otherwise, it won't
|
||||
- a name & a description
|
||||
- a capacity for our [Leaky Bucket](https://en.wikipedia.org/wiki/Leaky_bucket)
|
||||
- a leak speed for our [Leaky Bucket](https://en.wikipedia.org/wiki/Leaky_bucket)
|
||||
- a blackhole duration (it will prevent the same bucket from overflowing too often to limit spam)
|
||||
- some labels to qualify the events that just happen
|
||||
- a `debug` flag that allows to enable local debugging information.
|
||||
|
||||
|
||||
We are going to use the following sample log in our example :
|
||||
|
||||
```bash
|
||||

</details>
|
||||
|

|

We can see our "mock" scenario is working, let's see what happened :
|
||||
|
||||
- The first event (parsed line) is processed :
|
||||
|
||||
- The `filter` returned true (`1 == 1`) so the {{event.htmlname}} will be processed by our bucket
|
||||
- The bucket is instantiated in {{timeMachine.htmlname}} mode, and its creation date is set to the timestamp from the first log
|
||||
- The {{event.htmlname}} is poured in the actual bucket
|
||||
|
||||
- The second event is processed
|
||||
- The `filter` is still true, and the event is poured
|
||||
- As our bucket's capacity is `1`, pouring this second overflow leads to an {{overflow.htmlname}}
|
||||
- Because we set a blackhole directive of `1 minute`, we remember to prevent this bucket to overflowing again for the next minute
|
||||
|
||||
The overflow itself is produced and we get this message :
|
||||
|
||||
```
|
||||
INFO[12-05-2020 11:22:17] Processing Overflow with no decisions 2 IPs performed 'me/my-cool-scenario' (2 events over 0s) at 2020-05-12 09:40:15 +0000 UTC bucket_id=withered-brook event_time="2020-05-12 09:40:15 +0000 UTC" scenario=me/my-cool-scenario source_ip=66.66.66.66
|
||||
|
||||
```
|
||||
|
||||
!!! warning
|
||||
While it "worked" we can see the first issue : the offending IP is reported to be `66.66.66.66` but there are actually 3 IPs involved (`66.66.66.66`, `99.99.99.99` and `44.44.44.44`). To make sense our "detect port scans" should detect events coming from a single IP !
|
||||
|
||||
|
||||
## One step forward : peer attribution
|
||||
|
||||
Let's evolve our scenario to be closer to something meaningful :
|
||||
|
||||
|
||||
```yaml
|
||||
type: leaky
|
||||
debug: true
|
||||
name: me/my-cool-scenario
|
||||
description: "detect cool stuff"
|
||||
filter: "evt.Meta.log_type == 'iptables_drop' && evt.Meta.service == 'tcp'"
|
||||
groupby: evt.Meta.source_ip
|
||||
capacity: 1
|
||||
leakspeed: 1m
|
||||
blackhole: 1m
|
||||
labels:
|
||||
type: my_test
|
||||
```
|
||||
|
||||
What did we change ?
|
||||
|
||||
- we added a meaningful filter : we are only going to look into `iptables_drop` events, and only take care of `tcp` ones (see the parser we wrote in the [previous step](/write_configurations/parsers/))
|
||||
- we added a `groupby` directive : it's going to ensure that each offending peer get its own bucket
|
||||
|
||||
|
||||
Let's try again !
|
||||
|
||||
```bash
|
||||

|

|
||||
Let's see what happened :
|
||||
|
||||
- Thanks to our `groupby` key, we now see two different partition keys appearing (`partition=...`).
|
||||
It means that each peer will get its own bucket, and a "unique key" is derived from the groupby field value (here : the source IP)
|
||||
|
||||
- We see that we only have one overflow, and it correctly concerns `99.99.99.99` (it's the one that actually triggered two events). This is again thanks to the groupby key
|
||||
|
||||
|
||||
## One step forward : unique ports
|
||||
|
||||
|
||||
|
||||
Is it done ? not yet, but we're getting close !
|
||||
|
||||
To really qualify a port-scan, we want to rely on the number of unique probed ports. Let's arbitrarily decide that a port-scan is : "One peer trying to probe AT LEAST 15 different ports within a few seconds"
|
||||
|
||||
Our evolved scenario is now :
|
||||
|
||||
```yaml
|
||||
type: leaky
|
||||
debug: true
|
||||
name: me/my-cool-scenario
|
||||
description: "detect cool stuff"
|
||||
filter: "evt.Meta.log_type == 'iptables_drop' && evt.Meta.service == 'tcp'"
|
||||
groupby: evt.Meta.source_ip
|
||||
distinct: evt.Parsed.dst_port
|
||||
capacity: 15
|
||||
leakspeed: 5s
|
||||
blackhole: 1m
|
||||
labels:
|
||||
type: scan
|
||||
service: tcp
|
||||
|
||||
```
|
||||
|
||||
What did we changed :
|
||||
|
||||
- We add a `distinct` directive on the `evt.Parsed.dst_port`. It allows the bucket to discard any event with an already seen `evt.Parsed.dst_port`. (yes, like in SQL)
|
||||
- We changed `capacity` and `leakspeed` to be more relevant to our target
|
||||
- We fixed the `labels` so that the event makes sense !
|
||||
|
||||
|
||||
Let's see what it changes :
|
||||
|
||||
```bash
|
||||
./crowdsec -c ./dev.yaml -file ./x.log -type syslog

|

</details>
|
||||
|
||||
- We can see that the second event was discarded, because it had a destination port similar to the first one
|
||||
- No overflow were produced
|
||||
|
||||
|
||||
## Is it really working
|
||||
|
||||
Ok, **fingers crossed** our thing should be working.
|
||||
|
||||
Let's grab some real-life logs !
|
||||
|
||||
```bash
|
||||
$ wc -l kern.log
|
||||
78215 kern.log
|
||||
$ head -n1 kern.log

|
||||
May 12 12:09:00 sd-126005 kernel: ...
|
||||
```
|
||||
|
||||
We have around 80k lines averaging about 24h of logs, let's try !
|
||||
|

|

It seems to work correctly !
|
||||
|
||||
|
||||
## Hold my beer and watch this
|
||||
|
||||
|
||||
One I have acquire confidence in my scenario and I want it to trigger some bans, we can simply add :
|
||||
|
||||
|
||||
```yaml
|
||||
type: leaky
|
||||
debug: true
|
||||
name: me/my-cool-scenario
|
||||
description: "detect cool stuff"
|
||||
filter: "evt.Meta.log_type == 'iptables_drop' && evt.Meta.service == 'tcp'"
|
||||
groupby: evt.Meta.source_ip
|
||||
distinct: evt.Parsed.dst_port
|
||||
capacity: 15
|
||||
leakspeed: 5s
|
||||
blackhole: 1m
|
||||
labels:
|
||||
type: scan
|
||||
service: tcp
|
||||
remediation: true
|
||||
scope: ip
|
||||
```
|
||||
|
||||
|
||||
Adding `remediation: true` into the labels tells {{crowdsec.name}} that we should write a ban for the IP when the scenario is triggered !
|
||||
|
||||
Let's try :
|
||||
|
||||
- I copied the yaml file to a production system (`/etc/crowdsec/crowdsec/scenarios/mytest.yaml`)
|
||||
- I restart {{crowdsec.name}} (`systemctl restart crowdsec`)
|
||||
|
||||
Let's check if it seems correctly enabled :
|
||||
|
||||
```bash
|
||||
$ {{cli.bin}} list
|
||||

||||

|
||||
|
||||
|
||||
Let's launch (from an external machine, as {{crowdsec.name}} ignores events from private IPs by default) a real port-scan with a good old `nmap` :
|
||||
|
||||
```bash
|
||||
sudo nmap -sS xx.xx.xx.xx
|
||||
```
|
||||
|
||||
|
||||
and on our server :
|
||||
|
||||
```bash
|
||||
$ tail -f /var/log/crowdsec.log
|

...
|

# Writing Crowdsec scenario
|
||||
|
||||
> Please refer to []() if the parser doesn't exist
|
||||
|
||||
## Acquiring the logs
|
||||
|
||||
First step to test a scenario is to get the logs that trigger your wanted scenario.
|
||||
|
||||
## Write the yaml configuration file
|
||||
|
||||
The first configuration for a scenario is the [type]().
|
||||
It can uniq, trigger or leaky. Please [see here]() for more description about scenarios type.
|
||||
|
||||
```yaml
|
||||
type: leaky
|
||||
```
|
||||
|
||||
Then the `name`. Please write it in the form of `<github_account_name>/<scenario_name>` .
|
||||
|
||||
```yaml
|
||||
name: crowdsecurity/http-scan-uniques_404
|
||||
```
|
||||
|
||||
Describe in one sentence what this scenario trigger :
|
||||
|
||||
```yaml
|
||||
description: Detect multiple unique 404 from a single ip
|
||||
```
|
||||
|
||||
Now come the filter, the one that will decide if the incoming log will be store in our bucket.
|
||||
For the HTTP 404 scans, we want only logs from web request that return a `404`, `403` or `400` HTTP code:
|
||||
|
||||
```yaml
|
||||
filter: "evt.Meta.service == 'http' && evt.Meta.http_status in ['404', '403', '400']"
|
||||
```
|
||||
|
||||
Then we want to groupby this scenario for `source_ip` (ip of the attacker) :
|
||||
```yaml
|
||||
groupby: evt.Meta.source_ip
|
||||
```
|
||||
|
||||
And we want only one log to be store for each HTTP URI query by the attacker (no duplicate):
|
||||
```yaml
|
||||
distinct: evt.Meta.http_path
|
||||
```
|
||||
|
||||
We can say that if someone query 5 or more unknown or forbidden HTTP URI with a leakspeed of 10s, then it is probably a web scan:
|
||||
```yaml
|
||||
capacity: 5
|
||||
leakspeed: "10s"
|
||||
```
|
||||
|
||||
Then we want to blackhole it for 5minutes (because if the attacker crawl a lot, we don't want to be notofied for every 5 times HTTP 404/403/400):
|
||||
```yaml
|
||||
blackhole: 5m
|
||||
```
|
||||
|
||||
We also want to reprocess this scenarios if it happen for more heuristic:
|
||||
```yaml
|
||||
reprocess: true
|
||||
```
|
||||
|
||||
And then we give some labels to this scenario for remediation:
|
||||
```yaml
|
||||
service: http
|
||||
type: scan
|
||||
remediation: true
|
||||
```
|
||||

||||

## Where are whitelists
|
||||
|
||||
Whitelists are, as for most configuration, YAML files, and allow you to "discard" signals based on :
|
||||
|
||||
- ip adress or the fact that it belongs to a specific range
|
||||
- a {{expr.name}} expression
|
||||
|
||||
Here is an example :
|
||||
|
||||
```yaml
|
||||
name: crowdsecurity/my-whitelists
|
||||
description: "Whitelist events from my ipv4 addresses"
|
||||
whitelist:
|
||||
reason: "my ipv4 ranges"
|
||||
ip:
|
||||
- "127.0.0.1"
|
||||
cidr:
|
||||
- "192.168.0.0/16"
|
||||
- "10.0.0.0/8"
|
||||
- "172.16.0.0/12"
|
||||
expression:
|
||||
- "'mycorp.com' in evt.Meta.source_ip_rdns"
|
||||
```
|
||||
|
||||
## Hands on
|
||||
|
||||
Let's assume we have a setup with a `crowdsecurity/base-http-scenarios` scenario enabled and no whitelists.
|
||||
|
||||
Thus, if I "attack" myself :
|
||||
|
||||
```bash
|
||||
nikto -host 127.0.0.1
|
||||
```
|
||||
|
||||
my own IP will be flagged as being an attacker :
|
||||
|
||||
```bash
|
||||
$ tail -f /var/log/crowdsec.log
|
||||
time="07-05-2020 09:23:03" level=warning msg="127.0.0.1 triggered a 4h0m0s ip ban remediation for [crowdsecurity/http-scan-uniques_404]" bucket_id=old-surf event_time="2020-05-07 09:23:03.322277347 +0200 CEST m=+57172.732939890" scenario=crowdsecurity/http-scan-uniques_404 source_ip=127.0.0.1

|
||||
|
||||
```
|
||||
|
||||
## Create the whitelist by IP
|
||||
|
||||
Let's create a `/etc/crowdsec/crowdsec/parsers/s02-enrich/whitelists.yaml` file with the following content :
|
||||
|
||||
```yaml
|
||||
name: crowdsecurity/whitelists
|
||||
description: "Whitelist events from private ipv4 addresses"
|
||||
whitelist:
|
||||
reason: "private ipv4 ranges"
|
||||
ip:
|
||||
- "127.0.0.1"
|
||||
|
||||
```
|
||||
|
||||
and restart {{crowdsec.name}} : `sudo systemctl restart {{crowdsec.name}}`
|
||||
|
||||
## Test the whitelist
|
||||
|
||||
Thus, if we restart our attack :
|
||||
|
||||
```bash
|
||||
nikto -host 127.0.0.1
|
||||
```
|
||||
|
||||
And we don't get bans, instead :
|
||||
|
||||
```bash
|
||||
$ tail -f /var/log/crowdsec.log
|
||||
...
|
||||
time="07-05-2020 09:30:13" level=info msg="Event from [127.0.0.1] is whitelisted by Ips !" filter= name=lively-firefly stage=s02-enrich
|
||||
...
|
||||
^C
|
||||
$ {{cli.bin}} ban list
|
||||
No local decisions.
|
||||
And 21 records from API, 15 distinct AS, 12 distinct countries
|
||||
|
||||
```
|
||||
|
||||

||||
|
||||

||||
|
||||
Now, let's make something more tricky : let's whitelist a **specific** user-agent (of course, it's just an example, don't do this at home !).
|
||||
|
||||
Let's change our whitelist to :
|
||||
|
||||
```yaml
|
||||
name: crowdsecurity/whitelists
|
||||
description: "Whitelist events from private ipv4 addresses"
|
||||
whitelist:
|
||||
reason: "private ipv4 ranges"
|
||||
expression:
|
||||
- evt.Parsed.http_user_agent == 'MySecretUserAgent'
|
||||
```
|
||||
|
||||
again, let's restart {{crowdsec.name}} !
|
||||
|
||||
For the record, I edited nikto's configuration to use 'MySecretUserAgent' as user-agent, and thus :
|
||||
|
||||
```bash
|
||||
nikto -host 127.0.0.1
|
||||
```
|
||||
|
||||
```bash
|
||||
$ tail -f /var/log/crowdsec.log
|
||||
...
|
||||
time="07-05-2020 09:39:09" level=info msg="Event is whitelisted by Expr !" filter= name=solitary-leaf stage=s02-enrich
|
||||
...
|
||||
```
