AU.L2-3.3.6 Reduction & Reporting
Provide audit record reduction and report generation to support on-demand analysis and reporting.
Source: NIST SP 800-171 Rev 2 3.3.6
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.
