Discussion:
The intent of this requirement is to periodically re-evaluate which logged events will continue to be included in the list of events to be logged. The event types that are logged by organizations may change over time. Reviewing and updating the set of logged event types periodically is necessary to ensure that the current set remains necessary and sufficient.
Upon assessment, assessors must determine if-
3.3.3[a] a process for determining when to review logged events is defined.
3.3.3[b] event types being logged are reviewed in accordance with the defined review
process.
3.3.3[c] event types being logged are updated based on the review.
Assessors are instructed to-
Examine: [SELECT FROM: Audit and accountability policy; procedures addressing audit records and event types; system security plan; list of organization-defined event types to be logged; reviewed and updated records of logged event types; system audit logs and records; system incident reports; other relevant documents or records].
Interview: [SELECT FROM: Personnel with audit and accountability responsibilities; personnel with information security responsibilities].
Test: [SELECT FROM: Mechanisms supporting review and update of logged event types].
