Question

Quizplus · Accepted Answer

Stateful packet inspection firewalls keep track of each network connection established between internal and external systems by maintaining a state table. This table contains information about the connection, such as source and destination IP addresses, port numbers, and the current state of the connection. This allows the firewall to effectively filter traffic based on the context of the connection, rather than just individual packets like packet filtering firewalls do. Neither application layer or cache server firewalls specifically keep track of network connections in the same way as stateful packet inspection firewalls.
