Stateful inspection is a type of firewall that monitors ongoing network conversations and analyzes network communications to determine if packets are part of an ongoing dialogue between a sender and a receiver. It examines the context of packets to identify whether they are part of an established connection or a new one, and then allows or blocks the traffic based on predefined security policies. This technique provides more advanced security than traditional packet filtering, which only checks individual packets based on static rules. Intrusion detection systems and application proxy filtering are not specifically designed to analyze ongoing dialogues between senders and receivers.
