## Description
IAM (Identity and Access Management) is Google Cloud's centralized security framework for controlling access to resources. It uses a unified model with roles, permissions, and policies to enforce the principle of least privilege. Includes features like service accounts, policy bindings, and integration with external identity providers.


## Use Cases
Use when securing access to GCP resources, implementing compliance requirements, or managing team permissions across projects.

- Centralized access control

- Fine-grained permissions

- Integration with enterprise identity
