Sample decisions

Name the people authorized to isolate systems, revoke access, contact vendors, and brief executives.
Verify which identity, endpoint, cloud, email, SaaS, and network records can answer containment questions.
Separate confirmed facts, assumptions, unknowns, decisions needed, and next update timing.

Common mistakes

Listing an incident team without confirming who can actually make containment decisions.
