Intrusion Detection Systems (IDS) are critical security tools that monitor network traffic for suspicious activity and alert administrators in case of any potential threats. Snort is a popular open-source IDS that provides real-time traffic analysis and packet logging capabilities. In this article, we will discuss the steps to install and use Snort on Kali Linux.

Step 1: Installing Snort

The first step in using Snort on Kali Linux is to download and install Snort. You can download Snort from the official website and then install it by running the following command in the terminal:
