In this video, we will understand AWS IAM Permission Boundaries in a simple and practical way.

We will cover what permission boundaries are, how they work with identity-based policies, and how they define the maximum permissions an IAM user or role can have. You will also see a hands-on demo where we restrict an administrator user using a permission boundary and observe the effective permissions in action.

You will learn:
What is an IAM Permission Boundary
How it differs from identity-based policies
How effective permissions are calculated (intersection concept)
How to attach a managed policy as a permission boundary
How to test permission restrictions
How to remove a permission boundary safely

This is an advanced IAM concept and very important for AWS security, enterprise access control, and DevOps environments where delegated administration is required.
