Cloud IAM, or Cloud Identity and Access Management, is a framework that helps organizations manage user identities and control access to cloud resources. It allows administrators to define who can access specific data and applications, ensuring that only authorized users have the necessary permissions. By using Cloud IAM, businesses can enhance security and compliance while simplifying user management. This system typically includes features like user authentication, role-based access control, and activity monitoring, making it easier to protect sensitive information and maintain oversight of user actions in the cloud environment.
