Circuit Level Firewall
Hello All,
Quick one....
On the TechNotes it says:
"Another type of firewall is the circuit-level firewall that operates on the Transport layer of the OSI model." I also found the same on another site.
Meanwhile, most sites (as well as cert exam) and Exam Cram books say that they operate at the Session layer of the OSI model.
Am i missing something?
Thanks for the help.
