Question

Quizplus · Accepted Answer

Application-filtering firewalls, also known as proxy-based or stateful inspection firewalls, operate at a higher level of the OSI model compared to packet-filtering firewalls. They inspect the data being transmitted, making decisions based on the content of the traffic rather than just the header information like packet-filtering firewalls. This additional functionality requires more processing power and often more sophisticated software, which typically makes them more expensive than packet-filtering firewalls.
