Just-in-time access (JIT)

Just-in-time (JIT) access grants elevated rights only when they are needed, for a limited period, and removes them automatically once that period ends. Instead of accounts holding standing administrative access around the clock, access is provisioned on request, used, and withdrawn — leaving nothing permanently elevated for an attacker to find.

JIT access follows a request-and-expire pattern:

1. A user requests elevated access to a system, often with a reason.
2. The request is approved automatically by policy or by an approver.
3. Access is granted for a defined, limited window.
4. When the window ends, the access is revoked automatically.
5. The request and session are logged for audit.

Standing access is always-on: an account holds elevated rights permanently, whether or not they are in use. That permanent privilege is exactly what attackers seek. Just-in-time access replaces it with temporary, on-demand rights, so that at any given moment almost no elevated access exists to be compromised. The result is a dramatically smaller attack surface.

JIT access is least privilege applied to time as well as scope. Least privilege limits how much access an identity has; just-in-time limits how long it has it. Together they ensure access is both minimal and momentary — granted only to the right people, for the right resources, for only as long as needed.

Standing privileged access is one of the largest and most persistent risks in most environments. By removing it, just-in-time access shrinks the window in which any account can be abused, contains the damage a compromise can do, and produces a clean audit trail of who requested what and when. It is a foundational practice in privileged access and remote access management.
