ARP attacks can occur on a LAN, as there are many available tools. Many of the tools are built into Kali Linux. Kali Linux is a collection of software tools designed to assist the network administrator with conducting ethical hacking on a network. For a complete list, go to https://tools.kali.org/tools-listing. However, Kali Linux can be used in malicious ways as well. Some of the tools to launch an ARP attack include the following:

• Dsniff is a suite of tools that includes arpspoof, which allows a hacker to advertise a spoofed MAC address as a way to misdirect traffic.
• Ettercap is an easy-to-use tool for ARP attacks, along with other tools that make it possible to intercept network traffic.
• Arpoison is a free command-line tool that allows a hacker to custom build an ARP packet and define the sender and target addresses.

As you can see, there can be several ways to launch an ARP attack, and hackers have many tools at their disposal. The following section outlines some of the ways we can defend against ARP attacks.
