True or False: A stateful firewall remembers the state of connections.

A stateful firewall is designed to track the state of active connections and make decisions based on the context of those connections, rather than just inspecting individual packets in isolation. When a packet passes through a stateful firewall, it checks the packet against a state table that maintains information about all ongoing connections. This allows the firewall to understand whether packets are part of an established session or if they are new requests.

This ability to remember states means that the firewall can make more informed decisions about what traffic to allow or block based on the connection status. It can differentiate between legitimate traffic that is part of an established connection and unsolicited packets that do not have a corresponding entry in the state table. Thus, the assertion that a stateful firewall remembers the state of connections is indeed true.
