What is Audit Log?

Turkish: Audit Log

An audit log records critical system actions with user, time, resource, and outcome details to leave an inspectable trail.

What is an Audit Log?

An audit log is a record of important system actions kept so they can be reviewed later. Ordinary application logs often focus on debugging; an audit log answers “who did what, when, from where, and with what result?”

How Does It Work?

An audit entry usually includes user identity, action type, affected resource, before-and-after values, IP address, timestamp, and result. Records should be tamper-resistant or changes to the records should themselves be tracked; otherwise the evidence value becomes weak after misuse.

Administrator actions, permission changes, financial-record updates, data exports, and login attempts are common audit candidates.

Business Use

Finance, healthcare, e-commerce, and enterprise SaaS products need audit logs for both security investigations and compliance. Logging describes general event recording; an audit log is the inspectable, business-critical subset of those records. Under rules such as GDPR, traceability of personal-data access becomes especially important.

Audit-log design should consider data minimization, retention periods, access permissions, and search performance together.
