How to Run a Privileged Access Review

What this addresses

Privileged access is every permission that can change production systems, identity policy or sensitive business data. A quarterly list of account names is insufficient without recording who needs each permission and why.

Practical implementation steps

• Inventory human, service and emergency administrators; identify the application and accountable owner
• Compare each privilege with actual job duties and recent activity
• Remove unused grants through an approved change process
• Require MFA and separate everyday from administrative identities
• Document exceptions with an expiry date and reviewer

Acceptance test

Pick one account that no longer needs elevation. Confirm its normal work still succeeds while an administrative action is denied; retain evidence of both outcomes.

Common failure mode

Avoid treating shared root accounts as an audit substitute. Emergency access must also be protected, logged and rehearsed.

Build an entitlement map, not an account spreadsheet

Start with systems capable of changing identity, releasing software, exporting customer records or moving money. An account may look ordinary in the directory yet inherit administrator rights through a nested group or application-specific role. For each entitlement, record the person or workload using it, the business purpose, approving owner, grant mechanism and recovery dependency. Include contractors, deployment tokens and emergency identities. Never put token values or passwords in the review file; a secret identifier and responsible owner are enough.

Review a departure scenario from end to end

Consider an illustrative finance employee moving to another department. Disabling the old finance role in the main application does not establish that exported reports, shared folders, API tokens and delegated approvals have also been removed. Trace one realistic transaction through those surfaces. Ask the new manager to confirm the employee's remaining duties and the finance owner to approve withdrawal of the old permissions. Check direct grants separately from group membership; otherwise a manually granted exception can survive an apparently successful role change.

Remove access in a controlled sequence

Classify privileges as required, removable or unresolved. For removable grants, capture the current assignment, choose a change window and identify a rollback owner before making a change. Start with one account and verify its expected ordinary work. Use temporary, explicitly approved elevation for duties performed infrequently instead of leaving permanent administrator rights everywhere. Some legacy applications cannot express the desired narrow role; record that limitation, isolate the account and shorten the review interval while considering a safer integration or replacement.

Test service and emergency accounts differently

A service identity has no manager who can simply stop using a permission. Link it to a specific job, permitted resources and deployment owner. Rotate or revoke a test credential through the approved secret store and confirm the workload fails visibly rather than silently skipping work. Emergency access needs a different exercise: authorized staff should be able to recover control when the usual identity provider is unavailable, while every use produces an event for independent review. Restrict access to recovery material and avoid turning an emergency procedure into a daily bypass.

Evidence and operating cadence

Retain the before-and-after entitlement, owner decision, test result and unresolved exception. Useful measurements include orphaned privileged identities, grants with no documented purpose, overdue exceptions and time between a role change and effective revocation. Set the review frequency according to system impact and change rate; a high-turnover support team needs event-driven checks as well as periodic reviews. An approval email is evidence of a decision, not proof that the platform enforced it. Close the review only after a permitted operation succeeds and a prohibited operation is denied for the tested identity.
