FortiGate buffers the whole file, but transmits to the client simultaneously.
-
FortiGate buffers only a part of the file, and not transmits to the client simultaneously.
Frage 3
Frage
Flow-Based Inspection Mode—Full Scan Mode
Antworten
-
When the last packet 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—exceptlastpacket.
Lower perceived latency-data loads faster
-
When the first packet arrives, the AV engine starts the scan.
Files bigger than buffer size are scanned— can´t enable logging of these files.
Packets are not delayed by scan—except first packet.
Faster perceived latency-data loads lower

Frage 9
Frage
Regardless of which mode you use, the scan techniques give similar detection rates. How can you choose between the scan engines? If performance is your top priority:
Antworten
-
then flow inspection mode is more appropriate. If security is your priority, proxy inspection mode—with client comforting disabled—is more appropriate.
