Identity and Access Management (IAM)

Identity and Access Management (IAM) is the framework of policies, processes, and technologies for managing digital identities and controlling access to resources. IAM encompasses user provisioning (creating accounts), authentication (verifying identity), authorization (granting permissions), and deprovisioning (removing access when it's no longer needed).

A mature IAM program ensures that every person in your organization has exactly the access they need — no more, no less — and that access is promptly adjusted when roles change or employment ends. IAM systems often integrate with HR systems to automate access lifecycle management.

Why It Matters

Strong IAM is foundational to multiple CMMC domains. Knowing who has access to your systems and CUI, ensuring access is appropriate, and removing it promptly when no longer needed are requirements assessors will thoroughly evaluate.
