ISO 27001:2022 5.27: Learning from information security incidents
ISO 27001:2022 5.27 covers Learning from information security incidents. The held text names 5 evidence records for it, the first being Statement of Applicability entry for control A.5.27, showing inclusion or justified exclusion, implementation status and the risks it.... The common gap an assessor flags is Incident costs are never captured, so trends and business impact are unknown.
What the organization learns from its information security incidents is to be fed back to strengthen and improve its security controls. Purpose (stated in ISO/IEC 27002:2022): makes future incidents less likely or less harmful. As an Annex A reference control, it is compared with the controls determined in risk treatment (6.1.3 c) and recorded in the Statement of Applicability as included or excluded, with the justification and implementation status (6.1.3 d); implementation guidance is ISO/IEC 27002:2022 5.27.

Where this requirement comes from
This is our own statement of ISO 27001:2022 5.27, read from the copy we hold (licensed complete copy) and stated in our words, not the standard verbatim. The framework as we hold it.
Common gaps an assessor flags
- Incident costs are never captured, so trends and business impact are unknown
- Lessons are written up but the resulting actions are not tracked to completion
- The risk assessment is not revisited after significant incidents
- Recurring incident types are handled individually without any cause analysis
How it maps to SOC 2
- CC7.5 high Learning from incidents is the root cause activity this criterion tests.
A link is a topical overlap with a confidence and a reason. It does not establish that meeting one requirement satisfies the other, and it is not certification.
