Zero Standing Privilege: Enforcing Least Privilege in Real Time with the NIST Cybersecurity Framework

The NIST Cybersecurity Framework is clear: control access, limit privileges, and reduce attack surface. Yet most organizations leave standing admin rights in place long after they’re needed. This is where Zero Standing Privilege changes the game.

Zero Standing Privilege (ZSP) means no user or system holds permanent high-level access. Privileges are granted on-demand, for the exact task, then revoked. When privileges vanish after use, attackers have nothing to exploit. The NIST Cybersecurity Framework calls this least privilege—but ZSP refines it to real-time enforcement.

Under the NIST CSF, ZSP fits into several core functions:

• Identify: Catalog privileged accounts and roles.
• Protect: Implement just-in-time access systems and strong authentication.
• Detect: Monitor for privilege escalation attempts or unexpected use.
• Respond: Rapidly revoke temporary privileges if abuse is detected.
• Recover: Adjust privilege policies post-incident to close gaps.

Permanent admin accounts violate least privilege by definition. Even dormant privileges can be exploited through stolen credentials, insecure scripts, or lateral movement. ZSP reduces this risk by making access ephemeral—privileges exist only for a controlled window.

Practical implementation requires tooling that automates both granting and revoking rights. This is more than policy; it’s enforcement at speed. Integration with identity providers, real-time audit logging, and session-based privilege assignment are essential. Aligning with the NIST Cybersecurity Framework ensures ZSP isn’t an isolated control—it becomes part of a unified security architecture.

Attackers know privilege is power. Remove the standing part, and you remove their foothold.
