Principle of Least Privilege (PoLP)

The practice of granting users and services the minimum access they need to perform their duties.

Security FoundationsAlso called: "least privilege", "minimal privilege"

The principle of least privilege limits blast radius. If a user account or API key is compromised, the attacker can do only what that identity was allowed to do.

Common gaps

  • Standing admin access in production environments.
  • Shared credentials stored in chat or wikis.
  • Service accounts with overly broad permissions.

Good habits

  • Use role-based access with time-bound elevation workflows.
  • Automate access reviews and revoke stale permissions.
  • Require just-in-time access for privileged tasks.
