Research Methods for Hardening PFSense System with Snort for Security

This assignment details a practical guide on hardening a PFSense system using Snort for intrusion detection and port scan detection. The solution begins by explaining the initial steps of starting and configuring the Snort GUI within PFSense, including downloading and setting up community rules to manage emerging threats. It covers updating Snort rules, adding a Snort interface, and provides screenshots of the configuration process. The assignment further demonstrates the use of Kali Linux to perform a port scan using nmap, providing commands and results to illustrate how Snort detects these scans. The document includes a step-by-step instructional guide with screenshots, explaining hardening, Snort's function, and the rationale behind its use, alongside additional PFSense hardening methods. A bibliography with relevant sources is also provided, offering a comprehensive overview of network security and intrusion detection techniques, making it a valuable resource for students on Desklib.
