How PAM works
Three-step view of how it operates in practice.
- Discover. Inventory every privileged account — admin logins, domain accounts, service accounts, local admin passwords.
- Vault. Store credentials in a secure vault. Admins don’t know passwords directly; they check out access through the vault.
- Monitor & rotate. Every privileged session is logged or recorded. Passwords rotate automatically on a schedule or after each use.
Why PAM matters
Privileged credentials are the master keys — they open the finance system, the backups, and the security tooling itself, which is why attackers hunt them before anything else. Even a modest PAM practice at a small organization — separate admin accounts, rotation, and time-boxed elevation, removes the single most catastrophic failure mode an intrusion can reach, and it's a control insurers have started probing in detail.
Password manager vs IAM vs PAM vs just-in-time access
- Password manager. A vault that helps individuals store and fill strong passwords. Excellent hygiene for everyone, but no rotation enforcement, session recording, or control over what privileged accounts do.
- IAM. The organization-wide framework for all identities and access. PAM lives inside it as the specialized wing for the accounts that can do the most damage.
- PAM. Purpose-built control of elevated credentials: vaulted checkout, automatic rotation, session logging or recording, and approval workflows for the accounts that can change the environment.
- Just-in-time elevation. The modern refinement — nobody holds standing admin rights at all; elevation is requested, granted for a window, and expires. Increasingly the default expectation rather than an advanced feature.
Common PAM mistakes
- Vaulting without rotating. Storing admin passwords in a vault while they stay unchanged for years means every past screenshot, sticky note, and departed employee still holds a working key. Automatic rotation after use or on schedule is what makes the vault meaningful.
- Forgetting service accounts. The accounts running backups, integrations, and scheduled jobs often hold sweeping rights, never change passwords, and belong to no one. Inventory them, scope them down, and bring them under the same management as human admins.
- Standing global admin. Permanent top-tier rights on a daily-use account means one phishing success hands over the whole environment. Separate admin identities from daily accounts and make elevation temporary and logged.
