Audit evidence

Traceable evidence for every privileged action

This page models what an auditor would be shown: a tamper-evident trail of privileged operations, the policy decisions behind denials, and the evidence packs that back each control. The events below are fabricated — there is no live audit sink behind this application.

Evidence packs

Change evidence

Every schema or PL/SQL change carries a change reference, a reviewer and a rollback note. Deployment is pipeline-driven so the artefact hash is recorded alongside the change.

Access evidence

Grants are made to roles, never to people. Denied attempts are retained with the policy that produced the denial so recertification reviewers can see intent as well as outcome.

Retention evidence

Purge operations require a checksum manifest of the rows being removed. The manifest is written to a write-once sink before the delete commits.

Recovery evidence

Each restore rehearsal produces a drill record: timestamp, scope, measured RTO, reconciliation result and any follow-up actions raised.
