Facing TCP's three-way handshake protocol, how should attackers launch attacks? The attacker first intentionally initiated a handshake packet. After receiving it, the server puts it into the waiting queue and returns an acknowledgement. Secondly, the attacker will no longer send the third acknowledgement packet, thus the server will make multiple retransmissions (the Linux system configures the number of retransmissions through tcp_synack_retries), consuming a lot of extra overhead, and the waiting queue will be occupied, even the waiting queue will be full, eventually causing the server to be unable to receive the client's request. This is the attack.

TcpMaxHalfOpenRetried defines the number of half connections saved in the backlog queue and retransmitted. If this value is exceeded, the system automatically starts the SynAttackProtect mechanism. The default value for Win2000 server is 80 and for Win2000 Advanced server is 400.
