Policy Enforcement Point (PEP)

A Policy Enforcement Point (PEP) is a system component that acts as a gatekeeper in a security or access control setup. It sits between users or devices and the resources they want to access, ensuring that only authorized requests are allowed. When someone tries to access a resource, the PEP checks the access policies—rules about who can do what—and then approves or denies the request accordingly. Essentially, it enforces security policies in real-time, helping organizations control and protect their digital assets effectively.
