Just-in-time access approval with separation of duties is the safeguard that turns a potential breach into a non-event. By granting privileges only when needed—and only to those cleared through independent review—you shrink your attack surface and stop lateral movement before it begins.
Separation of duties means no single person can request and approve the same access. It breaks the chain that attackers exploit. Coupled with just-in-time provisioning, it eliminates standing privileges. Permissions expire as soon as the job is done. No lingering accounts. No forgotten admin tokens.
Implementing this requires a system that enforces workflow checks. Access approval must be routed to an approver who has no stake in the task being performed. Audit logs must capture the full lifecycle—request, review, approval, and revocation. All events must be immutable and exportable to meet compliance mandates like SOC 2, ISO 27001, or PCI DSS.
