Privileged User Monitoring (PUM)

What is privileged user monitoring (PUM)?

Privileged user monitoring (PUM) is the practice of recording and reviewing what accounts with elevated rights do: system and database administrators, root and service accounts, and third-party contractors. NIST defines a privileged user as one authorized to perform security-relevant functions that ordinary users cannot. PUM gives you an audit trail and a way to spot misuse early.

Why it matters

• A single compromised admin account can expose everything it can reach.
• Insider misuse, deliberate or careless, is easiest to catch in privileged activity.
• Many compliance frameworks expect audit trails for administrative actions. Check the exact wording in the one that applies to you.
• After an incident, the logs show what happened and in what order.

What PUM records

PUM and PAM

Privileged access management (PAM) controls who gets privileged access and for how long: vaulting, rotation, just-in-time grants. PUM watches what happens once access is granted. In practice PUM is one function inside a PAM programme. The two sit next to your identity and access management (IAM) and role-based access control setup, which decide who may hold privileges in the first place.

How it works in practice

1. List every privileged account, including service accounts and vendor access.
2. Route privileged sessions through a controlled point such as a bastion host or access proxy so they can be logged.
3. Ship logs to storage the admins themselves cannot edit.
4. Alert on unusual behaviour. User and entity behavior analytics (UEBA) builds a baseline and flags deviations, and an XDR platform can correlate them with other signals.
5. Review alerts and a sample of sessions on a schedule, and test that detection works.

Common mistakes

• Editable logs: a compromised admin deletes their own tracks.
• Unwatched service accounts: often more powerful than any person and rarely reviewed.
• Recording without review: footage nobody watches deters nothing.
• Too many alerts: noisy rules get ignored. Start with a few high-value ones.
• Shared admin passwords: you cannot tell who did what. Use individual accounts. See also database security.

Where LoadFocus fits

LoadFocus is not a PAM or monitoring product for privileged users and does not record admin sessions. What it can do alongside PUM is watch your own endpoints: API monitoring alerts you when an admin or login API slows down or fails, and load tests show how those systems behave under traffic. For test-data safety, see cloud testing security best practices.

FAQ: privileged user monitoring

What is the difference between PUM and PAM?

PAM controls who receives privileged access and under which conditions. PUM records and reviews what those users do. PUM is usually one part of a PAM programme.

Who counts as a privileged user?

Anyone whose account can do things ordinary users cannot: system and database administrators, root and cloud administrators, service accounts, and contractors with elevated access.

Does PUM require recording every session?

Not necessarily. Many teams log commands and queries for all privileged access and keep full session recordings for the riskiest cases, such as production databases and third-party access.

How is PUM different from UEBA?

PUM is the practice of watching privileged activity. UEBA is one technique for it: it learns normal behaviour and flags deviations.
