Title

The IDPS must provide audit record generation capability for detection events based on implementation of policy filters, rules, signatures, and anomaly analysis. (Cat II impact)

Discussion

Without the capability to generate audit records, it would be difficult to establish, correlate, and investigate the events relating to an incident, or identify those responsible for one. While auditing and logging are closely related, they are not the same. Logging is recording data about events that take place in a system, while auditing is the use of log records to identify security-relevant information such as system or user accesses. In short, log records are audited to establish an accurate history. Without logging, it would be impossible to establish an audit trail. The IDPS must have the capability to capture and log detected security violations and potential security violations.

Check Content

Verify the configuration provides audit record generation capability for detection events based on implementation of policy filters, rules, signatures, and anomaly analysis. If the IDPS does not provide audit record generation capability for detection events based on implementation of policy filters, rules, signatures, and anomaly analysis, this is a finding.

Fix Text

Configure the IDPS to provide audit record generation capability for detection events based on implementation of policy filters, rules, signatures, and anomaly analysis.
