ARP attack protection overview
Although ARP is easy to implement, it provides no security mechanism and is prone to network attacks.
An attacker may send:
ARP packets by acting as a trusted user or gateway so that the receiving devices obtain incorrect
•
ARP entries. As a result, network attacks occur.
A large number of IP packets with unreachable destinations. As a result, the receiving device
•
continuously resolves destination IP addresses and its CPU is overloaded.
• A large number of ARP packets to bring a great impact to the CPU.
For more information about ARP attack features and types, see ARP Attack Protection Technology White
Paper.
ARP attacks and viruses threaten LAN security. The switch can provide multiple features to detect and
prevent such attacks. This chapter mainly introduces these features.
