This section describes the definition and functions of Attack defense.


Attack defense is a network security feature. This feature enables the device to analyze the content and behavior of packets sent to the CPU for processing, check whether packets are attack packets, and take measures for attack packets.

Attack defense is classified into malformed packet attack defense, packet fragment attack defense, and flood attack defense.


Due to defects of communications protocols and network deployment problems, increasing network attacks have great impact on networks. In particular, attacks to a network device cause the device or network to crash.

The attack defense feature enables the device to discard or limit the rate of different types of attack packets sent to the CPU, protecting the device and ensuring normal services.
