Explanation

FLow-Base Inspection Mode 1. Optimized performance compared to proxy-based scan - used a hybrid of advanced scan modes available only in proxy-based profile - Proxy-based offers two scanning modes: default scanning and legacy scanning - Flow-based is designed to use a hybrid of proxy-based scanning modes 2. FortiGate buffers the whole file ,but transmits to the client simultaneously - When the last packets arrives , the AV engine starts the scan - Files bigger than buffer size are not scanned -can enable logging of these files - Packets are not delayed by scan -expect last packet - Lower perceived latency -data loads faster If the virus is detected, the last packet is dropped, and the connection is reset if an identical request is made, the block replacement page is inserted immediately (FortiGate Security 6.4
