Audit Trail is another name for which record?

• A. Audit Log
• B. Event History
• C. Security Log
• D. Transaction Log

Answer: (A)

An audit trail is a chronological record of system activities used to reconstruct events for security and compliance. The term maps directly to an audit log—the log that captures events, user actions, and changes with timestamps so you can trace who did what and when. This is exactly what PCI DSS requires for accountability and forensics.

The other options are related types of logs, but they don’t carry the exact overall meaning of an “audit trail” as commonly used in security and compliance contexts: an event history is a general term for recorded events, a security log focuses on security-related events, and a transaction log usually pertains to database or processing transactions. Therefore, the audit log is the best fit.
