Discussion:
Correlating audit record review, analysis, and reporting processes helps to ensure that they do not operate independently, but rather collectively. Regarding the assessment of a given organizational system, the requirement is agnostic as to whether this correlation is applied at the system level or at the organization level across all systems.
Upon assessment, assessors must determine if-
3.3.5[a] audit record review, analysis, and reporting processes for investigation and
response to indications of unlawful, unauthorized, suspicious, or unusual
activity are defined.
3.3.5[b] defined audit record review, analysis, and reporting processes are correlated.
Assessors are instructed to-
Examine: [SELECT FROM: Audit and accountability policy; procedures addressing audit record review, analysis, and reporting; system security plan; system design documentation; system configuration settings and associated documentation; procedures addressing investigation of and response to suspicious activities; system audit logs and records across different repositories; other relevant documents or records].
Interview: [SELECT FROM: Personnel with audit record review, analysis, and reporting responsibilities; personnel with information security responsibilities].
Test: [SELECT FROM: Mechanisms supporting analysis and correlation of audit records; mechanisms integrating audit review, analysis and reporting].
