Most breaches are not the result of complex zero-day exploits. They come from accounts that should not exist, access that should have expired, and permissions that never got reviewed. Security review of user provisioning isn’t a checklist. It’s the backbone of trust in every application.
User provisioning is more than adding and removing users. It defines who can touch what, when, and how. Without a tight loop of verification, orphaned accounts and excessive privileges grow unchecked. Attackers feed on that breathing room.
A strong security review process starts with precision in onboarding. Every new account should be tied to real, verified identities, with least privilege baked in from the start. Default roles should be minimal. Entitlement creep should be treated as a flaw, not an inevitability.
The same rigor must apply to deprovisioning. When a role changes or a contract ends, access must vanish immediately, not after the next sprint. Automation helps, but automation without review becomes a blind spot. Audit logs must be complete, immutable, and easy to read.
