What activity is essential for maintaining effective audit trails in CDX?

• A. Delete all logs after 30 days.
• B. Archive logs to offline storage.
• C. Regular reviews of tamper-evident logs.
• D. Ignore logs after deployment.

Answer: (C)

Maintaining trustworthy audit trails hinges on ongoing verification of recorded events and their integrity. Tamper-evident logs are designed so that any past modification becomes detectable, often through cryptographic hashes, signatures, or chained entries. By regularly reviewing these logs, you confirm that activities—like deployments, access, and configuration changes—are captured accurately and can be traced back to the responsible actions. This ongoing scrutiny helps spot anomalies, supports investigations, and ensures compliance, because you’ll know immediately if something altered the history of events. Deleting logs after a short window removes evidence and undermines accountability, making it impossible to reconstruct what happened. Archiving logs to offline storage can help with long-term retention, but without routine access and validation, you lose visibility and timely assurance of integrity. Ignoring logs after deployment eliminates a crucial source of post-deployment visibility into runtime activity and security events. Regularly reviewing tamper-evident logs keeps the audit trail reliable, usable, and defensible.
