Understanding Identity and Access Management

What Identity and Access Management really means

IAM is about identity, authentication, authorization, and access control.

It helps organizations manage accounts, permissions, sign-ins, roles, and access decisions across systems.

IAM systems keep track of identities and apply policies that define what each identity can do.

These systems often work with MFA, single sign-on, directory services, conditional access, and role-based permissions.
