Why are audit trails and non-repudiation important in AFCOMAC operations?

• A. They provide accountability and verify actions cannot be denied, supporting investigations and compliance.
• B. They are primarily for marketing analytics.
• C. They are optional and rarely used.
• D. They are only relevant to physical access control.

Answer: (A)

Accountability and verifiable actions are what audit trails and non-repudiation provide in AFCOMAC operations. An audit trail records a chronological sequence of activities—who did what, when, from where, and under what conditions—so every action is observable and reviewable. Non-repudiation strengthens this by cryptographically binding the action to its initiator, ensuring it cannot be denied later and that the record hasn’t been altered. Together, they create reliable, tamper-evident evidence that supports investigations and regulatory or policy compliance. For example, if a critical configuration change is made, the logs show the exact user, the time, and the nature of the change, and a digital signature helps ensure the record’s integrity. The other options miss the point: marketing analytics aren’t the purpose here, these capabilities aren’t optional, and they extend beyond just physical access control to cover digital actions and accountability across the system.
