Control Purpose

The organization must turn incident experience into better controls, procedures, awareness, risk treatment, and response capability.

Use A.5.27 Learning from Information Security Incidents for the detailed requirement, implementation guidance, audit checks, evidence expectations, and related ISO 27005 context.

Risk Logic

01 Security event
02 Weak incident process
03 Delayed or poor decision
04 Higher impact
05 Learning from Information Security Incidents
06 Evidence
07 Audit

No published risk scenario is linked to this control yet. Create or link a risk note under the risk knowledge base before treating this control as fully mapped.
