ZSP

ZSP is the Acronym for Zero Standing Privileges

A security strategy and an evolution of Privileged Access Management (PAM) that aims to eliminate always-on or persistent access. In a ZSP environment, no user or service account possesses administrative rights by default. Instead, privileges are granted dynamically and revoked immediately after the required task is completed. ZSP is the practical application of the Never Trust, Always Verify mantra within Zero Trust architecture.

How ZSP Functions

ZSP shifts the focus from managing accounts to managing tasks.

  • Request: A user requests access to a specific resource for a specific duration.
  • Validation: The system verifies the user’s identity (via MFA) and checks if the request aligns with their job role or a specific ticket.
  • Ephemeral Access: The system creates a temporary account or adds the user to a high-privilege group for a limited window (e.g., 30 minutes).
  • Automated Removal: Once the time expires or the task is complete, the privileges are stripped away, returning the user to Zero Privilege.

ZSP Core Benefits

ZSP reduces attack surfaces and simplifies auditing.

  • Reduced Attack Surface: Since there are no permanent admin accounts, there are no dormant high-value targets for hackers to hijack.
  • Lateral Movement Defense: If an attacker compromises a user, they cannot move through the network using inherited admin rights.
  • Simplified Auditing: Every privilege grant is tied to a specific request and timeframe, making the audit trail precise.
  • Blast Radius Limitation: Errors or malicious actions are confined to the brief window in which the privileges were active.

Table: Traditional PAM vs. ZSP

Traditional PAM (Standing Privileges)ZSP (No Standing Privileges)
Admins have accounts with always-on power.No one is an admin until they need to be.
Credentials are stored in a vault.Access is ephemeral (short-lived).
If the vault is breached or a session is hijacked, the attacker has a persistent foothold.This effectively removes the target from the map when it isn't being used.

The "Zero Trust" Connection

ZSP is considered the gold standard for access control.

  • Zero Trust Assumption: ZSP assumes that any standing privilege is a vulnerability waiting to be exploited.
