Question 510
At Cedarfield Hospitality, the infrastructure security team administers FortiGate-based protection for a group of hotels and central reservations systems under requirements for protected guest networks and reliable payment paths. An independent validation is requested for: A web application uses QUIC and bypasses inspection assumptions built only around TLS over TCP for the organization's protected web traffic. Which observed outcome BEST demonstrates that the intended correction works?
Explanation
Correct Answer
Controlled browser traffic follows the intended supported web inspection path and the bypass protocol is denied or handled explicitly. This outcome validates the intended correction for: A web application uses QUIC and bypasses inspection assumptions built only around TLS over TCP for the organization's protected web traffic. The associated approved corrective action is: Apply supported QUIC application control or a documented fallback inspection strategy for managed endpoints as required by policy. The Cedarfield Hospitality reviewer can therefore distinguish observable protection from an untested configuration claim.
Incorrect Answers
A supported managed client validates the new inspection certificate during a test session with no expired-certificate error. This would verify a separate corrective action: Renew or replace the inspection CA and distribute its trusted chain securely before activating the new policy certificate. That separate change addresses: An outbound TLS inspection profile presents a FortiGate CA certificate that expired and browsers reject every newly re-signed connection. It does not validate the current Cedarfield Hospitality issue: A web application uses QUIC and bypasses inspection assumptions built only around TLS over TCP for the organization's protected web traffic. The relevant acceptance evidence is: Controlled browser traffic follows the intended supported web inspection path and the bypass protocol is denied or handled explicitly.
An approved harmless test payload is visible to the applicable inspection engine while certificate-only mode remains limited to handshake metadata. This would verify a separate corrective action: Use a supported deep SSL inspection path with trusted enterprise endpoints when policy requires inspection of HTTPS payload content. That separate change addresses: An administrator enables certificate inspection but expects it to reveal malware hidden inside an encrypted HTTPS response body. It does not validate the current Cedarfield Hospitality issue: A web application uses QUIC and bypasses inspection assumptions built only around TLS over TCP for the organization's protected web traffic. The relevant acceptance evidence is: Controlled browser traffic follows the intended supported web inspection path and the bypass protocol is denied or handled explicitly.
The event identifies the effective IPS action for the specific signature and a subsequent approved sensor change behaves consistently. This would verify a separate corrective action: Inspect the matched firewall policy, assigned IPS sensor and signature override precedence for the controlled traffic. That separate change addresses: A large policy estate duplicates different IPS sensors with conflicting overrides and an engineer cannot determine which one applied to a particular connection. It does not validate the current Cedarfield Hospitality issue: A web application uses QUIC and bypasses inspection assumptions built only around TLS over TCP for the organization's protected web traffic. The relevant acceptance evidence is: Controlled browser traffic follows the intended supported web inspection path and the bypass protocol is denied or handled explicitly.
