How to Review Whether a Security Incident Is Contained

A blocked indicator does not prove that related accounts, hosts, or persistence mechanisms are no longer active.

Checks to make

Define containment criteria based on the incident hypothesis, review affected identities and systems, check for repeated indicators, and validate controls from a separate trusted vantage point. Document residual risk and monitor for recurrence before closing.
