Traditional firewall are stateless meaning they have no memory of the connections of data or
packets that pass through them. Such IP filtering firewalls simply examine header information in
each packet and attempt to match it to a set of define rule. If the firewall finds a match, the
prescribe action is taken. If no match is found, the packet is accepted into the network, or dropped,
depending on the firewall configuration.
A stateful firewall maintains a memory of each connection and data passing through it. Stateful
firewall records the context of connections during each session, continuously updating state
information in dynamic tables. With this information, stateful firewalls inspect each connection
terface of the firewall, testing the validity of data packets throughout each
session. As data arrives, it is checked against the state tables and if the data is part of the session,
it is accepted. Stateful firewalls enable a more intelligent, flexible and robust approach to network
security, while defeating most intrusion methods that exploit state-less IP filtering firewalls.
