Question 360
At Eastvale Transport Authority, the FortiGate 7.6 security administration team encounters the following authorized operational case: two interfaces in the same configured FortiGate zone exchange unexpected traffic because the zone's intrazone behavior was never reviewed. They need a defensible FortiOS configuration, diagnosis, validation or prevention decision. Which recurring review is most relevant to the same root risk?
Explanation
Correct Answer
Audit intra-zone permissions when expanding zone membership. This recurring practice addresses intra-zone allowed traffic because zone intrazone settings can govern whether traffic between its member interfaces bypasses ordinary expectations. It reinforces the supported change to set the supported zone intra-zone behavior to the intended security policy and add explicit rules as needed rather than relying on an unrelated periodic audit.
Incorrect Answers
Review protocol assumptions and collision limits before enabling fixed port reduces recurrence of fixed-port source nat requirement, rather than the observed intra-zone allowed traffic issue. The relevant preventive control for Eastvale Transport Authority is: Audit intra-zone permissions when expanding zone membership. This distinction matters because zone intrazone settings can govern whether traffic between its member interfaces bypasses ordinary expectations.
Include VIP policy semantics in inbound NAT change reviews reduces recurrence of policy match order with dnat, rather than the observed intra-zone allowed traffic issue. The relevant preventive control for Eastvale Transport Authority is: Audit intra-zone permissions when expanding zone membership. This distinction matters because zone intrazone settings can govern whether traffic between its member interfaces bypasses ordinary expectations.
Validate internal reachability before adding external NAT rules reduces recurrence of vip mapped address subnet gateway, rather than the observed intra-zone allowed traffic issue. The relevant preventive control for Eastvale Transport Authority is: Audit intra-zone permissions when expanding zone membership. This distinction matters because zone intrazone settings can govern whether traffic between its member interfaces bypasses ordinary expectations.
