Valerie's organization has deployed a zero-trust solution, and Valerie receives an authentication prompt when she is attempting to access a file server. What component of the zero-trust architecture is she interacting with?

Valerie is interacting with a policy enforcement point, the agent and resource-side elements that validate trust by requiring authentication and authorization before allowing access to a resource. The policy enforcement point will validate her access through the policy engine, which will be configured by the policy administrator. Trust managers are not a typical component of the zero-trust model.
