My Experience Creating My Own NIDS with Snort3

Over the past couple of months, I've went into the world of network intrusion detection systems (NIDS), crafting my own using Snort3. Snort3 is an open-source intrusion detection system (IDS) and intrusion prevention system (IPS) software developed by Cisco Talos. This software is designed to monitor network traffic and detect potential threats or malicious activity within a network. Snort3 is the latest version of the Snort software, which has been widely used in the cybersecurity community for many years.

One of the key features of Snort3 is its powerful rule-based detection engine, which allows users to define custom rules to identify specific patterns or signatures associated with known threats. These rules can be tailored to match various types of network traffic, including protocols, packet content, and behavioral patterns.

In addition to its detection capabilities, Snort3 also offers options for real-time packet logging, alerting, and blocking of suspicious traffic, making it a valuable tool for network security monitoring and defense. Overall, Snort3 is a valuable asset in the cybersecurity arsenal, providing network administrators and security professionals with a flexible and effective means of protecting their networks against a wide range of cyber threats.

This project has been a engaging one that has not only expanded my technical skills but also provided opportunities for experimentation.

Operating within my personal Kali Linux machine, I configured Snort3 to serve as a vigilant watchdog against cyber threats, ranging from sophisticated attacks to insidious malware. Throughout this journey, I gained valuable insights into the underlying structure of Snort rules, deciphering their syntax with relative ease.

While I wouldn't say I mastered it yet, navigating rule creation proved to be a surprisingly intuitive process, one that sparked a sense of accomplishment.

As I reflect on this project, I find myself a new phase in my project – the deployment of my NIDS onto a broader network environment. Whether it's integrating it within a server, a switch, or a router, this next step holds excitement.

This project has serves as a ongoing journey of discovery and growth that this project represents. In essence, crafting my own NIDS system using Snort3 has been an gratifying experience, one that has not only deepened my understanding of network security but also created a passion for exploration and innovation in this ever-evolving field.
