Attack Surface
An attack surface in permissions management refers to the sum total of all potential vulnerabilities that an unauthorized entity could exploit to gain access to a system or data.
Any system that acts as a standalone identity gateway is known as federated access. Google, by far, is one of the notable examples of federated identity access.
With Federated identity management (FIM), users don’t need new credentials to access applications that have federated agreements with Google, for instance, YouTube, Upwork, and numerous other applications.
All they need to remember is their Google credentials, which will act as a standalone login system for many other applications.
