The firewall identifies them by their lack of this type of response and blocks their spoofed connection attempts. The hit count decrements when the TCP three-way handshake completes. The firewall device drops packets sent from blacklisted devices early in the packet evaluation process, enabling the firewall to handle greater amounts of these packets, providing a defense against attacks originating on local networks while also providing second-tier protection for WAN networks.
