Audit trail

An audit trail captures a sequence of recorded events and activities in systems, applications, or business processes. By documenting who did what and when, audit trails provide transparency, enable forensic analysis, and support regulatory compliance and internal controls.

Audit trails collect events (logins, changes, transactions) with metadata such as timestamps, user IDs, source IPs, and affected objects. Records are written in append-only or tamper-evident storage, often hashed or signed, then aggregated and correlated for analysis, alerting, and long-term retention.

Common types include system logs (OS and infrastructure), application logs (user actions and workflows), transaction logs (financial or database changes), and security logs (access and authentication). Trail data may be stored locally, forwarded to centralized logging systems or SIEMs, and classified by sensitivity and retention needs.
