Question 260
A risk review at a retail network focuses on preventing this issue again: An organization needs to inspect inbound HTTPS for an owned public server but configures SSL Forward Proxy instead of the appropriate inbound certificate-based model. Which recurring control is most suitable?
Explanation
Correct Answer
Document certificate custody and decryption direction in architecture reviews. This control reduces recurrence of the documented mechanism: Forward proxy for clients and inbound inspection for owned services have different certificate roles. It creates a repeatable check around the needed response: Use the supported SSL Inbound Inspection configuration with the authorized server certificate and matching policy.
Incorrect Answers
Audit object memberships behind all high-impact No Decrypt entries. That safeguard addresses another potential failure: An administrator excludes a medical service from decryption with an address object that includes adjacent unrelated business hosts. It is not the most targeted recurring control for the described cause: Forward proxy for clients and inbound inspection for owned services have different certificate roles.
Include decryption error categories and policy matches in encrypted-traffic incident playbooks. That safeguard addresses another potential failure: A firewall displays TLS decryption errors for a client application but support changes the Security rule rather than investigating the Decryption log reason. It is not the most targeted recurring control for the described cause: Forward proxy for clients and inbound inspection for owned services have different certificate roles.
Maintain planned CA renewal, client rollout and rollback procedures for decryption. That safeguard addresses another potential failure: A certificate renewal for the firewall's decryption trust infrastructure is completed, but endpoint trust stores still contain only the retired issuer. It is not the most targeted recurring control for the described cause: Forward proxy for clients and inbound inspection for owned services have different certificate roles.
