Overview of Attack Defense

Overview of Attack Defense


Attack defense is a network security feature that enables a device to analyze the content and behavior of packets sent to the CPU, identify attack packets, and take measures to block attack packets.

Attack defense prevents malformed packet attacks, packet fragment attacks, and flood attacks.


Attacks initiated by utilizing inherent bugs of communication protocols or improper network deployment have great impact on networks. In particular, attacks on a network device can cause the device or network to crash.

The attack defense feature discards or limits the rate of various attack packets sent to the CPU, protecting the device and ensuring normal services.
