ARP Attack Protection Overview

Although ARP is easy to implement, it provides no security mechanism and thus is prone to network

attacks. An attacker can send

ARP packets by acting as a trusted user or gateway. As a result, the receiving device obtains

incorrect ARP entries, and thus a communication failure occurs.

A large number of IP packets with unreachable destinations. As a result, the receiving device

continuously resolves destination IP addresses and thus its CPU is overloaded.

A large number of ARP packets to bring a great impact to the CPU.

For details about ARP attack features and types, refer to ARP Attack Protection Technology White

Paper.

Currently, ARP attacks and viruses are threatening LAN security. The device can provide multiple

features to detect and prevent such attacks. This chapter mainly introduces these features.
