What is the primary purpose of the IPsec Policy Agent?

• A. Enforce IPsec policies on network traffic
• B. Intercept HTTPS traffic
• C. Encrypt all traffic
• D. Provide DNS resolution

Answer: (A)

IPsec Policy Agent enforces IPsec policies on network traffic. It reads the configured IPsec rules and ensures that the host’s communications comply with those rules, coordinating with the IPsec driver to apply the necessary protections. When traffic is supposed to be protected, the agent triggers the negotiation of security associations and routes packets through the IPsec stack to be encrypted and/or authenticated as specified. If traffic isn’t allowed or doesn’t meet the policy, it’s handled according to the rule (often blocked or dropped), ensuring consistent enforcement across the system. This isn’t about intercepting HTTPS traffic, which would require a proxy or TLS termination point; nor does it guarantee encryption of all traffic by default—IPsec protection follows the policy in place. It also has nothing to do with DNS resolution, which is a name-to-IP lookup service.
