Question 730
At Juniper University, the FortiGate 7.6 security administration team encounters the following authorized operational case: a recently released remote desktop client is not recognized by an outdated application-control database. They need a defensible FortiOS configuration, diagnosis, validation or prevention decision. What root condition most directly explains the described FortiGate symptom?
Explanation
Correct Answer
Application classification depends on signature intelligence that can become stale. The mechanism is relevant because the stated fortiguard application signature update incident concerns the actual selected path, policy, identity or inspection state. The appropriate response is to verify FortiGuard application signature updates and supported definitions for the client; verify it through this observed condition: the updated service identifies the controlled client and applies the correct action.
Incorrect Answers
Known-malware detection depends on current scan signatures in the chosen security profile explains a different situation, antivirus signature currency, where a branch detects older test files but misses a newer known sample because its AV signatures have not updated. It does not account for the specific observed fortiguard application signature update condition at Juniper University. The decisive mechanism here is: Application classification depends on signature intelligence that can become stale.
New threats may require reputation, behavior or updated intelligence beyond an old static signature explains a different situation, outbreak protection services, where known antivirus signatures miss a newly emerging threat family and the team assumes signatures are the only protective control. It does not account for the specific observed fortiguard application signature update condition at Juniper University. The decisive mechanism here is: Application classification depends on signature intelligence that can become stale.
Severity and attack filters determine which signatures enter a sensor's effective enforcement set explains a different situation, ips sensor severity filter, where a critical attack test is logged but not blocked because the sensor filter only selects low-severity signatures. It does not account for the specific observed fortiguard application signature update condition at Juniper University. The decisive mechanism here is: Application classification depends on signature intelligence that can become stale.
