Hi all!

I’ll try to be quick but I apologise first as I am pretty new to security stuff and my questions might be obvious to the more experts.

I have a VPS (hetzner) set up with docker, caddy for the reverse proxy, and authentik as the only login method for a couple of services (hedgedoc and forgejo). Since most of these has to be available and accessible on the internet, I also setup crowdsec and built caddy with the relevant bouncer. This allows crowdsec to inspect the caddy logs for all the services I am serving through it and act accordingly. Edit: all the services are in docker containers.

So far, so good. However, I also saw that crowdsec can directly monitor container logs with the docker integration or through container labels. Also, I saw a couple of collections on crowdsec hub specifically for Authentik and Gitea.

I feel I am missing something so my question are:

  1. Would it be useful to monitor container logs given my setup or would it be redundant?
  2. Should I add the app-specific collections, or would docker logs monitoring be enough?
My current crowdsec collections
  • crowdsecurity/linux
  • crowdsecurity/appsec-generic-rules
  • crowdsecurity/caddy
  • crowdsecurity/whitelist-good-actors
  • crowdsecurity/http-cve
  • crowdsecurity/iptables

Edit: bonus question, does someone know if the Gitea collection would be useful for Forgejo after it being a hard-fork now?

    Thanks for the answer :) make sense, I will go through with the plugins for the services I have exposed, although not all of them have crowdsec collections.

      You can easily create custom rules and bouncers if needed for something specific as well. They’re templatized for the most part. Possibly even something a stupid AI could kick out, but make sure you know what it’s doing, and don’t trust it outright.

        Thanks for the input, yes I was mostly thinking about hedgedoc, that doesn’t have parsers or anything. I need to delve more into crowdsec logic and rules before trying to do my own thing, for sure. Thanks a lot tough, I followed your advice and I got Crowdsec working on both Authentik and Forgejo :)
