Privileged Access Management: The Complete Guide

Privileged access management (PAM) is presented as a security discipline for controlling, monitoring, and auditing elevated access held by both people and machine identities, including administrators, service accounts, API keys, cloud roles, vendors, and AI agents. The discussion argues that permanent privileged access and unmanaged credentials increase breach impact, citing incidents involving stolen passwords, compromised third parties, hardcoded credentials, and OAuth tokens. Modern PAM aims to reduce this risk through least-privilege, just-in-time grants, MFA, approvals, credential vaulting and rotation, brokered connections, ephemeral credentials, session recording, and immutable audit logs. It distinguishes PAM from broader identity and access management (IAM) and privileged identity management (PIM), positioning PAM as the system governing credentials and activity during elevated sessions. Effective implementation begins with discovering accounts and dependencies, prioritizing high-impact systems, integrating with identity providers, replacing standing access gradually, maintaining emergency break-glass processes, and measuring reductions in persistent privileges. The text also describes PAM applications across cloud, Linux, Windows, Active Directory, hybrid environments, and compliance programs, before presenting Infisical as an open-source, self-hostable platform that combines PAM with secrets, certificate, SSH, and key management.
