How it works and where it fits

Machine Identity separates the subject, digital identity, authentication factor, and authorization decision. Authentication establishes who or what is presenting an identity; authorization then determines which action is permitted in the current context. Session state, device trust, request origin, and risk signals can further influence that decision.

Practical security relevance

Effective implementation requires a controlled identity lifecycle from creation through role and entitlement changes to suspension and removal. Strong authentication, least privilege, periodic recertification, and traceable logs are central. Controls must also identify abuse of legitimate accounts, because valid credentials alone do not prove that an action is legitimate.
