Definition & Explanation

The moment a clerk opens a customs declaration, changes a value, or releases a consignment, the system writes a timestamped entry into the audit log. An audit log is a tamper-proof, chronological record of all system events and user actions – capturing who accessed what, when, and what was changed. In customs and logistics operations, it serves as primary evidence during regulatory inspections, confirming that declarations were handled correctly and that no unauthorized modifications occurred. It differs from an audit trail, which covers the full end-to-end business transaction rather than system-level events alone.
