Event Horizon: Is This Even Needed?

Thanks! Ive been pouring my tokens into it recently and its been very nice. I think homelab’s in general suffer from potential rot due to not much alerting/log reading as its definitely the most boring part of the job. I also work in cyber in incident response and architecture, so maybe im just a bit paranoid but building an AI SOC/SOAR was a neat idea.

The local AI’s while generally are good at reading and saying something might be wrong, I dont trust them for incident response. The closest they get to it in my setup is a blocklist that propagates to different things. That blocklist had a trial through fire though when it blocked my VPN provider and my WAN address :facepalm: . Needless to say I have them on a whitelist now, I also exempt RFC1918 too because it got silly one time.

So my advise is, keep it advisory. I have my daily and especially weekly report layout some things to check/verify/cleanup. Anything super critical though the hourly will flag and raise the DEFCON level to critical (from normal or suspicious). If you do have it do any kind of response, it needs to be basic and with some guardrails. Like maybe a service restart, or a machine reboot. Also a sub-agent to verify the finding that is a different model is a good idea. My main model is currently Ornith-1.5-35B-A3B for the “analyst” with web search capabilities. There is an “agent” gets dispatched to confirm and investigate things thats currently on the model Swift-Qwen3.8-27B. its purposely a different more technical model so it can provide a different prospective vs the analyst.

I’m definitely always refining and enhancing this though. Very interested in your project though from a hardware/software lifecycle monitoring perspective. Windows and Linux has great logging facilities for this already, but most of the tools to actually alert for anomalies costs too much money for the low (software) budget homelabers like myself.

Hy @wendell ,

Thanks for all your work - it looks really promising! I watched your YouTube -video, and now I’m really interested in testing it out in a dev-environment. Is there a repo where I can get a working container or something?

@Grassyloki Your dashboard also looks promising. Since I’m also running Wazuh and need a way to automate the detection, I really would like to test your setup. Can you point me to your repo?

Thank’s folks, for your efford!

Came here from the weekly Linux video.

If you are still looking for input and feedback I think there is a niche for dead simple system monitoring based off sysmon, and other log/file sources that don’t require an agent. I think it just depends on what exactly the end goal is. Troubleshooting? I think its fine on it own. Full security monitoring? Ehh…

If people want to use this for a DFIR tool/IR tool, I think you would have better results with a more EDR/XDR agent combined with some kind of SIEM. This gives me EDR/SIEM-lite vibes and I think it would still be a good tool for those who like to tinker but don’t want to go down the whole route of setting up a SecurityOnion instance (or the like).

If you were looking to expand functionality of your tool you could try integrations with VirusTotal, AbuseIPDB, ThreatFox and some other CTI feeds if you are leaning more towards the IR side of things. Hell, maybe even a MISP integration if that is really what the goal is.

Some PCAP analysis withe local AI could be useful as well. I think that is what you are going for in screenshot 7 but I am not sure. Having the alert fire and then being able to upload a PCAP for similar or related activity could be useful for troubleshooting and correlation. Similar to SO-Crates

This looks fun and I would like to try and tinker when you feel comfortable sharing. Full disclosure I am a full time security “engineer”.
