Why IAM Matters in Modern Security

This lesson explains why Identity and Access Management matters in modern security. It frames IAM as the control layer that connects people, services, devices, applications, and data to the access decisions an organization makes every day.

Learners will see how IAM reduces breach risk, supports productivity, enables compliance, and provides visibility into who did what, when, and under what conditions. The lesson focuses on practical security outcomes rather than deep implementation details, which are covered in later lessons.
