Question 290
At Dunwell Energy Cooperative, the FortiGate 7.6 security administration team encounters the following authorized operational case: an authorized overnight vendor maintenance flow stops working after a policy's time schedule expires. They need a defensible FortiOS configuration, diagnosis, validation or prevention decision. What root condition most directly explains the described FortiGate symptom?
Explanation
Correct Answer
A scheduled firewall policy does not match outside its configured active time window. The mechanism is relevant because the stated firewall schedule expiration incident concerns the actual selected path, policy, identity or inspection state. The appropriate response is to align the policy schedule to the approved maintenance period instead of opening it permanently; verify it through this observed condition: the connection works during the approved test window and is denied outside that period.
Incorrect Answers
Internal-to-public VIP access can require explicit route, policy and source NAT handling for return symmetry explains a different situation, hairpin nat internal-to-public hostname, where office clients cannot reach an internal application by its public DNS hostname even though external users can. It does not account for the specific observed firewall schedule expiration condition at Dunwell Energy Cooperative. The decisive mechanism here is: A scheduled firewall policy does not match outside its configured active time window.
Broad all-port destination translation exposes unnecessary services behind a public address explains a different situation, vip security exposure minimization, where a development server's new VIP publishes every TCP port when only HTTPS is required. It does not account for the specific observed firewall schedule expiration condition at Dunwell Energy Cooperative. The decisive mechanism here is: A scheduled firewall policy does not match outside its configured active time window.
Authentication success alone does not necessarily provide session start, stop or accounting records explains a different situation, radius accounting visibility, where security operations cannot correlate user logoff events because the FortiGate implementation collects only RADIUS authentication results. It does not account for the specific observed firewall schedule expiration condition at Dunwell Energy Cooperative. The decisive mechanism here is: A scheduled firewall policy does not match outside its configured active time window.
