Question 210
At Westhaven Retail, the perimeter security team administers FortiGate-based protection for an international commerce and warehouse network under requirements for segmented store traffic and consistent branch connectivity. An independent validation is requested for: An administrator allows all TCP and UDP ports for one business application because its required destination service objects were not identified. Which observed outcome BEST demonstrates that the intended correction works?
Explanation
Correct Answer
The permitted application ports connect while a controlled attempt to an unrelated port hits the intended denial rule. This outcome validates the intended correction for: An administrator allows all TCP and UDP ports for one business application because its required destination service objects were not identified. The associated approved corrective action is: Define narrowly scoped FortiGate service objects or groups for the documented application ports and apply them to its allow policy. The Westhaven Retail reviewer can therefore distinguish observable protection from an untested configuration claim.
Incorrect Answers
An internal test client connects to the service's approved public hostname without leaking unintended internal services. This would verify a separate corrective action: Design the supported internal-to-VIP access policy and necessary NAT and route behavior for the specific local topology. That separate change addresses: Internal users cannot reach a service by its public virtual IP because the relevant hairpin or same-interface DNAT path is not configured. It does not validate the current Westhaven Retail issue: An administrator allows all TCP and UDP ports for one business application because its required destination service objects were not identified. The relevant acceptance evidence is: The permitted application ports connect while a controlled attempt to an unrelated port hits the intended denial rule.
The diagnostic record reveals the correct identity and rule match, and a targeted change restores approved access without broad bypass. This would verify a separate corrective action: Correlate the FSSO logged-on user table, group mapping and matching firewall policy before modifying access controls. That separate change addresses: An FSSO user cannot reach an application and the engineer changes an unrelated web filter profile instead of checking identity policy matching. It does not validate the current Westhaven Retail issue: An administrator allows all TCP and UDP ports for one business application because its required destination service objects were not identified. The relevant acceptance evidence is: The permitted application ports connect while a controlled attempt to an unrelated port hits the intended denial rule.
An authorized finance account reaches the application while an unrelated signed-in account on the same subnet is denied. This would verify a separate corrective action: Apply FortiGate identity-based policy matching with the required authenticated group in addition to source and destination objects. That separate change addresses: Two user groups share the same subnet but an address-only allow policy grants both access to a restricted finance application. It does not validate the current Westhaven Retail issue: An administrator allows all TCP and UDP ports for one business application because its required destination service objects were not identified. The relevant acceptance evidence is: The permitted application ports connect while a controlled attempt to an unrelated port hits the intended denial rule.
