Parameter description
Parameter
Description
Used to enable or disable the ICMP flood attack defense.
The ICMP flood attack means that, to implement attacks on the target host, the
attacker sends a large number of ICMP Echo messages to the target host, which
causes the target host to spend a lot of time and resources on processing ICMP
Echo messages, but cannot process normal requests or responses.
ICMP Flood Attack
Defense
Used to enable or disable the TCP flood attack defense.
The TCP flood attack means that, to implement attacks on the target host, the
attacker quickly initiates a large number of TCP connection requests in a short
period of time, and then suspends in a semi-connected state, thereby occupying a
large amount of server resources until the server denies any services.
TCP Flood Attack
Defense
Used to enable or disable the UDP flood attack defense.
The UDP flood attack is implemented in a similar way with ICMP flood attack, during
which the attacker sends many UDP packets to the target host, causing the target
host to be busy processing these UDP packets, but unable to process normal packet
requests or responses.
