(For example, a packet could be part of a new connection, or it could be part of an existing connection.) … In addition, you can also exempt certain packets from the state-tracking machinery.

What is stateful vs stateless firewall?

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.

What are the two basic functions of a firewall?

A firewall is a protective measure that safeguards an individual’s or company’s computer network. It provides two basic security functions, including packet filtering, which inspects traffic at the packet level, and acting as an application proxy, providing security measures at the application level.
