Question

Quizplus · Accepted Answer

Packet-filtering firewalls are the simplest type of firewall as they examine data packets as they enter or exit a network and compare them against a set of predefined rules to determine whether to allow or block them. Perimeter firewalls are more complex and usually protect an entire network perimeter, while ACL firewalls are a type of packet-filtering firewall that use access control lists to filter traffic. Circuit-level firewalls work at the session layer of the OSI model and create a virtual circuit between the client and server, but are not as commonly used as packet-filtering firewalls.
