praeco VS HELK

I am using https://github.com/johnsusek/praeco/releases , they are supporting elastalert with elastic up to 7.14.

Utilizing that api and juniper notebooks is exactly why Hunting Elk is the way it from my understanding.

So you can actual do both defensive while practicing offensive. If you can set up a lab system with an attacker, for ease using kali, and defensive systems like a single windows box, or you can go balls to the wall if you have the resources and set up an AD environment and then ship all the logs to a SIEM system like Splunk or HELK (https://github.com/Cyb3rWard0g/HELK). Building off the environment you can also include Mordor (https://github.com/UraSecTeam/mordor)

HELK + Mordor combo https://github.com/Cyb3rWard0g/HELK

On a side note - I somehow have the feeling that you are trying to recreate https://github.com/Cyb3rWard0g/HELK

You can find tools that leverage ELK that aren't necessarily plugins. SIEM looks like it has some free component to it, too: https://github.com/Cyb3rWard0g/HELK https://www.elastic.co/blog/elastic-siem-free-open

HELK can help for the SIEM and detection part

MISP is a Threat Intelligence Platform (TIP), not a hunting platform. That would be something like HELK
