Annex A 5.27
Learning from information security incidents
Knowledge from incidents is used to strengthen controls.
What an assessor looks for
Trace at least one incident to a control change, a risk reassessment or a training update. The link from lesson to change is exactly what is being tested.
Where it usually fails
Post-incident reviews produce actions that are never assigned, tracked or closed.
