Configuration Guide 552
Configuring Network Security DoS Defend Configuration
SYN sPort less
1024:
The attacker sends the illegal packet with its TCP SYN field set to 1 and source port
smaller than 1024.
Blat Attack: The attacker sends the illegal packet with the same source port and destination
port on Layer 4 and with its URG field set to 1. Similar to the Land Attack, the system
performance of the attacked host is reduced because the Host circularly attempts to
build a connection with the attacker.
Ping Flooding: The attacker floods the destination system with Ping packets, creating a broadcast
storm that makes it impossible for the system to respond to legal communication.
SYN/SYN-ACK
Flooding:
The attacker uses a fake IP address to send TCP request packets to the server. Upon
receiving the request packets, the server responds with SYN-ACK packets. Since the
IP address is fake, no response will be returned. The server will keep on sending SYN-
ACK packets. If the attacker sends overflowing fake request packets, the network
resource will be occupied maliciously and the requests of the legal clients will be
denied.
WinNuke Attack Because the Operation System with bugs cannot correctly process the URG (Urgent
Pointer) of TCP packets, the attacker sends this type of packets to the TCP port139
(NetBIOS) of the host with the Operation System bugs, which will cause the host with
a blue screen.
3) Click Apply.
