What should be included in a post-mission log integrity check?

• A. Tamper indicators, chain of custody, and access logs.
• B. Only the date and time of mission end.
• C. Soft copies of the logs stored locally.
• D. Logs are optional after a mission.

Answer: (A)

Post-mission log integrity checks verify that the records of what happened during the mission remain authentic, unaltered, and traceable. Tamper indicators help you immediately know if any changes were made to the log data. A documented chain of custody shows who handled the logs and when, which is essential for audits or investigations. Access logs reveal who viewed or modified the logs, highlighting potential unauthorized activity and ensuring only approved personnel can interact with the records. When these elements are combined, you gain a trustworthy, auditable record of the mission.

Documenting only the date and time misses the actual events and any changes, so it doesn’t protect against tampering or prove who handled the logs. Storing soft copies locally can be vulnerable to modification or loss and often lacks strong evidence of provenance or controlled access. If logs are treated as optional, there’s no reliable way to reconstruct events or verify integrity after the fact.
