How to protect Cisco Devices against ARP poisoning attack
How to protect Cisco Devices against ARP poisoning attack The Address Resolution Protocol (ARP) is a communication protocol used for discovering the link layer address, such as a MAC address, associated with a given internet layer address, typically an IPv4 address. ARP spoofing, ARP cache poisoning, or ARP poison routing, is a technique by which an attacker sends (spoofed) Address Resolution Protocol (ARP) messages onto a local area network. Generally, the aim is to associate the attacker's MAC address with the IP address of another host, such as the default gateway. Within a Layer 2 broadcast domain, hosts can be vulnerable to MAC spoofing attacks as there is is no way to verify that indeed the host that replied to a ARP request is indeed to host who owns the required IP address. Hosts will also accept a gratuitous ARP reply even when they have not requested this information leading to a compromise of the hosts ARP cache. Cisco’s Dynamic ARP Inspection (DAI) feature can help prvent these types of attacks by ensuring only valid ARP requests and response are relayed. It does this by relying on an existing trusted database, either statically configured or via the DHCP snooping databae.
