Question 330
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. An independent validation is requested for: A firewall rule requires explicit user login for domain-joined employees even though the approved design should use passive single sign-on. Which observed outcome BEST demonstrates that the intended correction works?
Explanation
Correct Answer
A known signed-in domain user matches the intended policy without an unnecessary FortiGate credential prompt. This outcome validates the intended correction for: A firewall rule requires explicit user login for domain-joined employees even though the approved design should use passive single sign-on. The associated approved corrective action is: Use the supported Fortinet Single Sign-On identity mapping for the relevant Active Directory users and policy groups. The Alpine Healthcare reviewer can therefore distinguish observable protection from an untested configuration claim.
Incorrect Answers
The authorized external test packets reach the FortiGate and are translated to the intended server without spoofing another public range. This would verify a separate corrective action: Verify upstream ownership and routing or ARP behavior for the public VIP address and maintain the matching FortiGate policy. That separate change addresses: A FortiGate administrator creates a VIP on a WAN address that is not actually routed to the firewall and expects the DNAT rule alone to attract traffic. It does not validate the current Alpine Healthcare issue: A firewall rule requires explicit user login for domain-joined employees even though the approved design should use passive single sign-on. The relevant acceptance evidence is: A known signed-in domain user matches the intended policy without an unnecessary FortiGate credential prompt.
A controlled connection completes in both directions and FortiGate session diagnostics show the same intended translation path. This would verify a separate corrective action: Align ingress and return routing and NAT behavior for the VIP flow before broadening policy access. That separate change addresses: An inbound VIP maps to the correct server but response packets leave through a different WAN path, breaking stateful DNAT sessions. It does not validate the current Alpine Healthcare issue: A firewall rule requires explicit user login for domain-joined employees even though the approved design should use passive single sign-on. The relevant acceptance evidence is: A known signed-in domain user matches the intended policy without an unnecessary FortiGate credential prompt.
Controlled requests from each department show the correct distinct approved public source address in external records. This would verify a separate corrective action: Assign the intended source NAT IP pools to the relevant policies or supported central NAT mappings by department. That separate change addresses: Several departments must egress through different public addresses for attribution but all FortiGate policies use the WAN interface address. It does not validate the current Alpine Healthcare issue: A firewall rule requires explicit user login for domain-joined employees even though the approved design should use passive single sign-on. The relevant acceptance evidence is: A known signed-in domain user matches the intended policy without an unnecessary FortiGate credential prompt.
