Which option best describes the role of audit trails in HR systems?

• A. Enable public sharing
• B. Remove encryption
• C. Track access and changes to data
• D. Replace password policy

Answer: (C)

Audit trails provide accountability and traceability in HR systems by recording who accessed employee records, what actions they took, and when those actions occurred. This enables monitoring for unauthorized activity, verifying changes, and supporting audits and regulatory compliance. That’s why tracking access and changes to data is the best description. The other options don’t fit: public sharing would violate privacy, removing encryption would weaken protection, and replacing a password policy is a separate security control rather than a logging function.
