Stateful packet filtering: A method of network security in which the firewall maintains information about the state of packets in a network and uses this information to determine whether or not to allow traffic through. It is commonly used in enterprise-level network security. Examples include a stateful packet filtering firewall that tracks the state of packets in a network or a stateful packet filtering router that tracks the state of packets in a network.
