Discussion:
Audit record reduction is a process that manipulates collected audit information and organizes such information in a summary format that is more meaningful to analysts. Audit record reduction and report generation capabilities do not always emanate from the same system or organizational entities conducting auditing activities. Audit record reduction capability can include, for example, modern data mining techniques with advanced data filters to identify anomalous behavior in audit records. The report generation capability provided by the system can help generate customizable reports. Time ordering of audit records can be a significant issue if the granularity of the time stamp in the record is insufficient.
Upon assessment, assessors must determine if-
3.3.6[a] an audit record reduction capability that supports on-demand analysis is
provided.
3.3.6[b] a report generation capability that supports on-demand reporting is provided.
Assessors are instructed to-
Examine: [SELECT FROM: Audit and accountability policy; procedures addressing time stamp generation; system design documentation; system security plan; system configuration settings and associated documentation; system audit logs and records; other relevant documents or records].
Interview: [SELECT FROM: Personnel with audit record reduction and report generation responsibilities; personnel with information security responsibilities].
Test: [SELECT FROM: Audit record reduction and report generation capability].
