Detailed explanation-1: -The stateful inspection firewall (also known as circuit-level proxy or gateway) makes decisions about which traffic to allow based on virtual circuits or sessions. The firewall is considered stateful because it keeps track of the state of a sessions.

Detailed explanation-2: -Stateful firewalls are capable of monitoring and detecting states of all traffic on a network to track and defend based on traffic patterns and flows. Stateless firewalls, however, only focus on individual packets, using preset rules to filter traffic.

Detailed explanation-3: -How a Stateful Firewall Works. A stateful firewall collects data regarding every connection made through it. All of these data points form profiles of “safe” connections. When a subsequent connection is attempted, it is checked against the list of attributes collected by the stateful firewall.

Detailed explanation-4: -To start, a firewalled system analyzes network traffic based on rules. A firewall only welcomes those incoming connections that it has been configured to accept. It does this by allowing or blocking specific data packets-units of communication you send over digital networks-based on pre-established security rules.
