There are many attacks that are used against ARP21such as: DOS attack, MITM attack, MAC flooding, MAC duplicating, MAC address spoofing, and session hijacking. The Address Resolution Protocol (ARP) Spoofing attack, also called ARP Cache Poisoning or ARP Poison Routing, is a technique by which an attacker sends spoofed ARP messages onto a Local Area Network (LAN). An ARP poisoning attack exploits the ability of the attacker to gain accesses to and use sensitive data just as the authorized person in the network is able to. Also known as DNS spoofing, DNS cache poisoning is an attack designed to locate and then exploit vulnerabilities that exist in a DNS, or domain name system, in order to draw organic traffic away from a legitimate server and over to a fake one. However, it will still be susceptible to MAC spoofing, as well as the complications that arise from trying to manage too many devices. Security is a pervasive problem when using ARP. It is used to allow the attacker access to incoming internet traffic on a LAN by having their Media Access Control (MAC) Address be linked to the Internet Protocol (IP) Address of another host (usually, the default gateway). Although you can increase your protection against ARP spoofing with malware tools, it’s still important to use other techniques that include detection. When you connect to the internet, you typically first connect to an Internet Service Provider (ISP) in order to connect to another website. It performs ARP inspection and drops strange ARP responses.
