Question 280
At Dunwell Transport Authority, the FortiGate 7.6 security administration team encounters the following authorized operational case: an approved application flow is denied because a broad deny rule appears above a narrower intended allow rule. 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
Review shadowed rules after every policy insertion. This recurring practice addresses top-down firewall policy matching because fortiGate policy evaluation follows ordered matching rules and can stop at an earlier broad matching action. It reinforces the supported change to reorder or narrow the overlapping policies so the intended specific allow rule matches first rather than relying on an unrelated periodic audit.
