What element is necessary to include in audit logs to meet CMMC system auditing requirements?

To meet the CMMC system auditing requirements, it is essential to include success or failure indications in audit logs. This requirement ensures that organizations can track not just when actions are attempted within their systems, but also the outcomes of those actions. Recording this information allows for a clear understanding of user activity, which is critical for identifying potential security incidents, unauthorized access attempts, and compliance with security policies.

For example, if a user attempts to access a sensitive file but fails, logging this failure provides important context for security personnel. It signals potential malicious activity, such as attempted breaches or misuse of credentials. Conversely, successful access logs help in verifying that users are accessing information they are authorized to see.

In contrast, other options like user email addresses, file size details, or geographical locations may provide some information but do not directly address the core necessity of auditing for authorization and access control, which is fundamental to maintaining security compliance and mitigating risks.
