Which Windows service enforces IPsec policies for all network communications initiated from the system?

• A. IPsec Policy Agent
• B. IKE
• C. ESP
• D. DOI

Answer: (A)

IPsec Policy Agent is the Windows service that enforces IPsec policies across all network communications initiated by the system. It loads the IPsec rules defined locally or by domain policy and ensures every connection adheres to those rules, deciding whether to allow, block, or protect traffic. When a policy requires encryption, it coordinates with the key-exchange component to establish the necessary security associations, after which the actual protection is applied by the IPsec protocols. The IKE component handles the key exchange, ESP provides the encryption and authentication of the payload, and DOI isn’t the service responsible for enforcing policies. So, the policy enforcement across the system’s network traffic is handled by the IPsec Policy Agent.
