Question 170
At Oakridge Public Services, the municipal network protection team administers FortiGate-based protection for citizen services and remote public offices under requirements for restricted data exchange and defensible access policy. The security reviewer verifies a claimed fix for: A cloud firewall rollout uses the same interface identifiers as a hardware FortiGate and creates policy matches against nonexistent virtual ports. Which observed outcome BEST demonstrates that the intended correction works?
Explanation
Correct Answer
A policy trace identifies the actual ingress and egress virtual interfaces and authorized traffic matches the intended rule. This outcome validates the intended correction for: A cloud firewall rollout uses the same interface identifiers as a hardware FortiGate and creates policy matches against nonexistent virtual ports. The associated approved corrective action is: Inventory the virtual FortiGate interface mapping and bind policies and zones to the real cloud-connected NICs. The Oakridge Public Services reviewer can therefore distinguish observable protection from an untested configuration claim.
Incorrect Answers
The capture demonstrates whether test packets reach the intended interface and isolates any upstream path failure without broad packet collection. This would verify a separate corrective action: Run a permitted narrowly filtered packet sniffer at the expected ingress path before changing policy or NAT rules. That separate change addresses: A new firewall policy is believed to block a flow but the traffic never reaches the FortiGate's ingress interface. It does not validate the current Oakridge Public Services issue: A cloud firewall rollout uses the same interface identifiers as a hardware FortiGate and creates policy matches against nonexistent virtual ports. The relevant acceptance evidence is: A policy trace identifies the actual ingress and egress virtual interfaces and authorized traffic matches the intended rule.
A test policy change and traffic event arrive on the intended syslog collector with the expected device identification. This would verify a separate corrective action: Configure the supported remote syslog destination, transport and required event selection consistently at both endpoints. That separate change addresses: A distributed security operation relies on syslog messages from FortiGate but the configured collector port and delivery protocol differ. It does not validate the current Oakridge Public Services issue: A cloud firewall rollout uses the same interface identifiers as a hardware FortiGate and creates policy matches against nonexistent virtual ports. The relevant acceptance evidence is: A policy trace identifies the actual ingress and egress virtual interfaces and authorized traffic matches the intended rule.
The review locates both the intended accepted-traffic evidence and a separate high-severity security event through accurate filters. This would verify a separate corrective action: Configure the relevant log categories and selection criteria based on investigation requirements rather than conflating severity and traffic action. That separate change addresses: A compliance reviewer cannot distinguish log severity from firewall accept-or-deny action and discards needed accepted-traffic records. It does not validate the current Oakridge Public Services issue: A cloud firewall rollout uses the same interface identifiers as a hardware FortiGate and creates policy matches against nonexistent virtual ports. The relevant acceptance evidence is: A policy trace identifies the actual ingress and egress virtual interfaces and authorized traffic matches the intended rule.
