Access review frequency for outsourced programmers

An evidence-based framework for choosing event-driven and periodic access reviews.

Access-review frequency should reflect account risk, work duration, privilege, and change events. A single calendar interval cannot represent a short low-risk ticket and an administrator role with production access equally well.

NIST access-control guidance addresses account management and periodic review, while CISA Secure by Design emphasizes reducing avoidable exposure. The evidence supports both scheduled review and immediate event-driven review.

Trigger a review when a project ends, responsibilities change, elevated access expires, an account becomes inactive, or an incident affects identity controls. Periodic checks then catch drift not covered by those events.

A review record should connect each named account to an active owner, approved purpose, privilege level, last use, authentication controls, and removal decision. Shared credentials weaken that evidence and should not be treated as equivalent.

Measure orphaned accounts, overdue removals, unjustified elevated roles, and time from offboarding event to access removal. Do not use login frequency as a proxy for contribution.

Research takeaway: combine risk-based periodic reviews with immediate lifecycle events and keep approval for privileged access inside the company.
