From Wikipedia, the free encyclopedia. In computing, a stateful firewall (any firewall that performs stateful packet inspection (SPI) or stateful inspection) is a firewall that keeps track of the state of network connections (such as TCP streams, UDP communication) traveling across it. stateful firewall keeps track of the state of network connections (such as TCP streams or UDP communication) and is able to hold significant attributes of each connection in memory.
In a firewall that uses stateful inspection, the network administrator can set the parameters to meet specific needs, for example ports can be closed unless an incoming packet requests connection to a specific port and then only that port is opened.This practice prevents port scanning, a well-known hacking technique.tateful inspection can monitor communications packets over a period of time and examine both incoming and outgoing packets. Outgoing packets that request specific types of incoming packets are tracked and only incoming packets that are proper responses are allowed through the firewall.
