# Integrity and event reference

Audit logs are tamper-evident. Each entry includes a content hash and the previous entry hash.

Any change to history breaks the chain.

### What we log

Events are grouped into these categories:

* **Authentication**: logins, logouts, password changes, 2FA, session actions
* **Authorization**: access denied attempts
* **Data access**: recording views, downloads, exports
* **Data changes**: create, edit, delete recordings, captures, folders, labels
* **Admin actions**: SSO/SCIM changes, integrations, automation and triage rules
* **Security**: suspicious activity, rate limiting, invalid tokens
