From the clients with THE MOST mature security operations, we learn the so-called “tri-team” model for detection and response:
- SOC – primarily monitoring and threat detection in near real-time, and of course alert triage.
- CSIRT – security incident response
- “Threat something” (no standard name: we heard “theat fusion center”, “threat management center’’”, “threat intelligence team” and many others) – profile threat actors, organize and refine threat intelligence, create internal intel, hunt, etc [in a few cases, in fact, the intel creation and hunting teams were separate too, or hunting was with the CSIRT above]
This model allows for a clean, logical separation – but also collaboration! – between detection/monitoring, response and intelligence functions. It also seems to align well with the skills of the analysts hired for each function (e.g. ex-intel agency people fit into #3). Of course, there are many, many tricks to making it work in real life, and having a 9-digit security budget helps a lot too….
