ENTERPRISE · IDENTITY · ENTRA ID

Identity is
the boundary.

Practical notes on Microsoft Entra ID, authentication, authorization and access governance.

Identity

Users, groups, service principals and workload identities.

Authentication

Modern authentication, MFA and strong authentication controls.

Conditional Access

Turn identity, device and risk signals into access decisions.

Governance

Least privilege, privileged access and lifecycle management.

Security model

A useful mental model is to treat identity as a policy decision point: establish who is requesting access, from what context, to which resource, and under which conditions.

Identity → Signals → Policy → Decision → Resource

Operational focus

Keep privileged access narrow, document policy intent and monitor authentication failures. When troubleshooting, preserve the exact timestamp, user, application, device and policy evaluation context.
