Question 440
At Granite SaaS, the platform network security team administers FortiGate-based protection for a hosted business application and remote administrator fleet under requirements for per-tenant access restrictions and reliable telemetry. The security reviewer verifies a claimed fix for: A device mistakenly applies a private corporate CA certificate as the identity for an unrelated public web server during TLS interception. Which observed outcome BEST demonstrates that the intended correction works?
Explanation
Correct Answer
A managed test browser trusts only the intended enterprise inspection chain and an unexpected origin identity remains blocked or flagged. This outcome validates the intended correction for: A device mistakenly applies a private corporate CA certificate as the identity for an unrelated public web server during TLS interception. The associated approved corrective action is: Use the correct authorized inspection CA for outbound re-signing and preserve verified origin certificate identities in the inspection decision. The Granite SaaS reviewer can therefore distinguish observable protection from an untested configuration claim.
Incorrect Answers
A bounded approved traffic simulation exercises the intended anomaly threshold while a separate IPS signature test remains functional. This would verify a separate corrective action: Use the appropriate DoS or anomaly protection policy separately from IPS content signatures for the documented flood risk. That separate change addresses: A security architect assumes an IPS sensor alone rate-limits volumetric floods and omits the needed FortiGate DoS controls. It does not validate the current Granite SaaS issue: A device mistakenly applies a private corporate CA certificate as the identity for an unrelated public web server during TLS interception. The relevant acceptance evidence is: A managed test browser trusts only the intended enterprise inspection chain and an unexpected origin identity remains blocked or flagged.
The verified legitimate package downloads and an unrelated antivirus test indicator is still detected by the active profile. This would verify a separate corrective action: Validate the false positive and apply a narrowly scoped supported exception with review and expiration while retaining other protections. That separate change addresses: Antivirus blocks a legitimate internal application package after a false-positive signature but the help desk disables the entire protection profile. It does not validate the current Granite SaaS issue: A device mistakenly applies a private corporate CA certificate as the identity for an unrelated public web server during TLS interception. The relevant acceptance evidence is: A managed test browser trusts only the intended enterprise inspection chain and an unexpected origin identity remains blocked or flagged.
The authorized application works on its documented transport while a different application on the same path is denied. This would verify a separate corrective action: Use supported application-control matching and precise allowed service ports rather than a blanket any-service forward rule. That separate change addresses: A network team changes service objects to allow all ports after an application receives a new transport port even though policy requires application-specific access. It does not validate the current Granite SaaS issue: A device mistakenly applies a private corporate CA certificate as the identity for an unrelated public web server during TLS interception. The relevant acceptance evidence is: A managed test browser trusts only the intended enterprise inspection chain and an unexpected origin identity remains blocked or flagged.
