The set of controls used to manage, monitor, and secure high-privilege accounts and systems. PAM limits who can use administrative credentials, under what conditions, and with what oversight.
What PAM Protects Against
Privileged Access Management is the discipline of controlling who gets the keys to the kingdom. Administrative accounts, the ones that can modify systems, access sensitive databases, change security configurations, or bypass normal access controls, are the highest-value targets in any organization.
The risk without PAM is concrete. An attacker who compromises a standard user account can access that user's files. An attacker who compromises an admin account can access everything and can cover their tracks. Insider threats work the same way: a disgruntled administrator with unchecked access can cause damage that a standard user couldn't.
PAM controls the blast radius. Elevated access is granted only when needed, monitored while in use, and automatically revoked when the task is complete.
Core PAM Capabilities
PAM systems provide several controls.
- Privileged account discovery: identify all administrative accounts across the environment, including service accounts and shared credentials that may not be formally tracked.
- Password vaulting: store admin credentials in an encrypted vault rather than in spreadsheets or personal password managers.
- Just-in-time access: grant elevated privileges for a specific task and a specific time window, then revoke them automatically.
- Session recording: capture a full record of what was done during privileged sessions for audit and forensic purposes.
- Approval workflows: require that elevated access be requested and approved before credentials are released.
Just-in-Time Access
Just-in-time access is the PAM mechanism that most directly implements least privilege. A developer who needs to deploy to production doesn't need permanent production admin access, they need it for the duration of the deployment, and then it should expire. This approach limits exposure: a credential that's only valid for 30 minutes provides a much smaller attack window than a permanent administrative credential.
PAM in Compliance Frameworks
Most serious compliance frameworks specifically address privileged access.
- SOC 2's CC6 common criteria require that privileged access is controlled and monitored.
- ISO 27001 requires that the allocation of privilege information rights is controlled.
- PCI DSS requires that system component access is restricted to authorized individuals with a business need.
PAM and user access review tools, when offered by best IT management platforms like ZenAdmin, provide the technical control that satisfies these requirements with auditable evidence.
