ARP attacks and how to prevent them

chenhui · Created Oct 24, 2020 01:43:28

Hi,
The most common ARP attacks might be the MITM(man in the middle). An MITM attacker establishes connections with two ends and exchanges data between them. The two ends consider that they are directly communicating, but actually the attacker has controlled the entire session. In an MITM attack, the attacker intercepts all packets going between the two ends and inserts new ones.
Usually, most of the ARP attacks could be prevented by configuring the DAI. You can refer https://support.huawei.com/hedex/hdx.do?docid=EDOC1100064949&id=dc_fd_ARP_SEC_0010&lang=en

Hello friend!

Attackers usually steal authorized users' IP addresses to connect to networks and initiate ARP attacks to interrupt network communication.
To defend against ARP attacks, a static user binding table and dynamic ARP inspection (DAI) can be configured for static users. DAI checks ARP packets based on binding entries.
Run the user-bind static command to configure the static user binding table, and run the arp anti-attack check user-bind enable command to enable DAI.

Thanks!
