Application Security Engine Support ( #2273 )
...
Add a new datasource that:
- Receives HTTP requests from remediation components
- Apply rules on them to determine whether they are malicious or not
- Rules can be evaluated in-band (the remediation component will block the request directly) or out-band (the RC will let the request through, but crowdsec can still process the rule matches with scenarios)
The PR also adds support for 2 new hub items:
- appsec-configs: Configure the Application Security Engine (which rules to load, in which phase)
- appsec-rules: a rule that is added in the Application Security Engine (can use either our own format, or seclang)
