Magento 2 Security: Verifying ACL Protection in Custom Admin Modules
A custom Magento Admin module is not secure merely because it declares an ACL resource and checks authorization in a controller. Sensitive backend access must be tested against real restricted roles and validated after deployment.

Security and module risks we investigate
Admin authorization boundaries
Validate that ACL resources, controller enforcement, and role behavior produce deterministic denied access where required.
Custom module exposure
Identify backend routes, actions, and module features that can expose sensitive operations without explicit authorization testing.
Role and permission drift
Detect production role configurations and stored rule states that diverge from expected least-privilege access behavior.
Security verification workflow
Strengthen deployment QA with allowed/denied role testing, direct URL checks, and repeatable access-control verification steps.

A Forensic Platform Audit can evaluate custom Magento modules, Admin access controls, extension exposure, authorization behavior, and the technical risks affecting sensitive platform operations.
