It applies not only to administrator accounts, but also to service accounts, application secrets, automation, emergency access, and other identities with elevated capability.
PAM aims to replace permanent, poorly attributable privilege with controlled access for a specific identity, purpose, and time. Depending on the environment, it may include credential vaulting, approval workflows, just-in-time elevation, session brokering or recording, command restrictions, and secret rotation.
The practical sequence matters more than the product list: first discover every privileged account and secret — standing admin rights, hardcoded credentials, forgotten service accounts — then vault or federate them, then add elevation workflows and session controls. Vaulting alone changes little if the same standing privileges and shared accounts remain in daily use underneath it.
Key points
Primary purposeReduce the likelihood and impact of misuse or compromise of powerful access.
Good designNamed identities, least privilege, short-lived elevation, strong authentication, separated duties, and monitored emergency procedures.
Machine access mattersSecrets used by software and automation can be as powerful as human administrator credentials.
Important limitationA password vault alone is not a complete PAM program, and PAM does not make a compromised privileged session harmless.
