What must be included in audit records to support user activity traceability?

To ensure effective user activity traceability within audit records, comprehensive action descriptions are essential. These descriptions provide details about the specific actions taken by users on a system, allowing auditors to accurately track user behaviors and interactions with sensitive data or system functionalities.

Incorporating robust action descriptions helps establish a clear connection between users and their activities, which is crucial for identifying potential security incidents, ensuring compliance with policies, and fulfilling requirements related to data protection. Without detailed descriptions, it would be challenging to interpret the context and legitimacy of user actions, ultimately undermining the effectiveness of the audit records.

Other options, while they may have their own purposes, do not directly contribute to user activity traceability in the same way. For instance, system performance ratings and user feedback may provide insights into system usability and efficiency but lack specificity regarding user actions. Handling times for Controlled Unclassified Information (CUI) can inform about processing efficiency but do not offer full visibility into what users actually did. Therefore, the need for comprehensive action descriptions stands out as the most critical component for traceability in audit records.
