Question 640
At Alpine Healthcare, the clinical infrastructure security team administers FortiGate-based protection for multiple clinics connected to private records systems under requirements for patient-data access control and high uptime. Following the approved change, the team must validate: A security architect assumes an IPS sensor alone rate-limits volumetric floods and omits the needed FortiGate DoS controls. Which observed outcome BEST demonstrates that the intended correction works?
Explanation
Correct Answer
A bounded approved traffic simulation exercises the intended anomaly threshold while a separate IPS signature test remains functional. This outcome validates the intended correction for: A security architect assumes an IPS sensor alone rate-limits volumetric floods and omits the needed FortiGate DoS controls. The associated approved corrective action is: Use the appropriate DoS or anomaly protection policy separately from IPS content signatures for the documented flood risk. The Alpine Healthcare reviewer can therefore distinguish observable protection from an untested configuration claim.
Incorrect Answers
An obsolete-protocol test handshake is rejected and a current supported TLS connection completes under the same policy. This would verify a separate corrective action: Apply the suitable TLS protocol security settings and supported inspection profile while documenting the application upgrade path. That separate change addresses: A legacy outbound application uses an obsolete TLS protocol and security policy requires it to be blocked rather than silently bypassed. It does not validate the current Alpine Healthcare issue: A security architect assumes an IPS sensor alone rate-limits volumetric floods and omits the needed FortiGate DoS controls. The relevant acceptance evidence is: A bounded approved traffic simulation exercises the intended anomaly threshold while a separate IPS signature test remains functional.
Controlled browser traffic follows the intended supported web inspection path and the bypass protocol is denied or handled explicitly. This would verify a separate corrective action: Apply supported QUIC application control or a documented fallback inspection strategy for managed endpoints as required by policy. That separate change addresses: A web application uses QUIC and bypasses inspection assumptions built only around TLS over TCP for the organization's protected web traffic. It does not validate the current Alpine Healthcare issue: A security architect assumes an IPS sensor alone rate-limits volumetric floods and omits the needed FortiGate DoS controls. The relevant acceptance evidence is: A bounded approved traffic simulation exercises the intended anomaly threshold while a separate IPS signature test remains functional.
A controlled inbound HTTPS request is decrypted for the intended security profiles and the browser validates the correct public service identity. This would verify a separate corrective action: Configure the supported inbound SSL inspection or TLS termination method using the approved certificate and key management process. That separate change addresses: FortiGate inbound deep inspection for a published HTTPS application has no access to a usable certificate and private key for the protected service. It does not validate the current Alpine Healthcare issue: A security architect assumes an IPS sensor alone rate-limits volumetric floods and omits the needed FortiGate DoS controls. The relevant acceptance evidence is: A bounded approved traffic simulation exercises the intended anomaly threshold while a separate IPS signature test remains functional.
