INITIAL ALERT

A role receives AccessDenied despite a newly attached allow policy.

You are primary on-call. Establish the failure domain, protect healthy capacity, and choose the safest next action.

KNOWN-GOOD BASELINE

The request resource and condition keys match the identity allow.

The decisive evidence and solution remain locked inside the simulation.

WHAT THIS TESTS

Production judgment across IAM · Permissions Boundary.

An attached Allow is only one part of effective authorization. Production diagnosis requires checking explicit denies, boundaries, resource policies, session conditions, and credential lifetime.

  1. 01Evaluate layered AWS authorization
  2. 02Recognize token and rotation failures
  3. 03Restore access without broad permissions
