User Provisioning vs Deprovisioning: Why Termination Controls Matter

Access-control failures often happen not when accounts are created, but when access is never updated or removed.

Provisioning

Provisioning grants access based on approved job responsibilities, least privilege, and appropriate authorization.

Changes

Transfers and role changes should trigger timely access updates so old privileges do not accumulate.

Deprovisioning

Termination or separation should trigger prompt revocation of accounts, credentials, tokens, privileged access, and remote connectivity as appropriate.

Exam strategy

Look for stale access. A technically strong authentication system still fails if former users or transferred employees keep privileges they no longer need.

The takeaway

Strong logical access control covers the full user lifecycle: approve, provision, review, modify, and promptly deprovision.
