What does IAM stand for, and why is it central to security?

• A. Integrated Access Management stands for IAM.
• B. Identity and Access Management controls who can access what resources, enforcing authentication, authorization, and auditing.
• C. IAM is only about password storage.
• D. IAM eliminates need for security.

Answer: (B)

Identity and Access Management is the practice of managing user identities and controlling access to resources. Its central role in security comes from its three core functions: authentication to verify who someone is, authorization to determine what they’re allowed to do, and auditing to record what happened for accountability and compliance. By tying permissions to identities and enforcing least-privilege through policies, IAM reduces who can access sensitive data and actions, lowering the attack surface and aiding incident response. It’s not just about password storage, and it doesn’t remove the need for security; it provides the structured framework to enforce access controls consistently across systems, often with features like multi-factor authentication and single sign-on. This combination makes IAM a foundational security layer in modern environments.
