How does FortiGate perform antivirus scanning on files?

FortiGate performs antivirus scanning by utilizing both signature-based detection and heuristic analysis. Signature-based detection involves scanning files against a database of known malware signatures. This method allows FortiGate to identify and block known threats effectively.

In addition to signature-based detection, FortiGate employs heuristic analysis to identify previously unknown viruses or new variants of known viruses. This type of analysis examines the behavior and characteristics of files to assess their potential maliciousness, allowing for proactive detection of threats that may not yet have a defined signature.

Thus, the combination of these two techniques enables FortiGate to provide robust antivirus protection, making it capable of identifying both known and emerging threats as they pass through the firewalls and security devices.
