Project Overview: I am seeking a skilled cybersecurity professional to assist with two critical assignments focused on network security: the installation and configuration of a Next-Generation Firewall (NGFW) using pfSense (or OPNsense) and the deployment of an Intrusion Detection/Prevention System (IDS/IPS) using Snort, Suricata, or Zeek. Assignment 1: Next-Generation Firewall (NGFW) Objective: Install pfSense (or OPNsense) as a virtual machine. Set up a management PC and a client PC as virtual machines. Configure the firewall to control internet access, set up a captive portal, and integrate pfBlocker-NG for enhanced security. Tasks: Install pfSense in VirtualBox with 1GB RAM and two virtual NICs. Set up management and client PCs with lightweight operating systems (e.g., Ubuntu). Configure NTP, basic firewall rules, and restrict internet access for the client PC. Implement traffic shaping and a captive portal. Install and configure the pfBlocker-NG package, and set up a Virtual IP for NAT. Assignment 2: IDS/IPS Implementation Objective: Utilize the existing firewall setup to add an IDS/IPS system. Install and configure Snort, Suricata, or Zeek to monitor network traffic and prevent potential threats. Tasks: Set up a NAT to access the internal server using Virtual IP. Install and configure the chosen IDS/IPS in non-blocking mode. Test the IDS/IPS by simulating web application attacks and verify alert generation. Enable blocking mode and confirm that offensive IP addresses are blocked. Explore and write custom signatures for detection. Install Zeek, configure it, and demonstrate rule customization.

Hello, I have 25 years of cybersecurity experience. For your two projects I recommend a WatchGuard Next-Generation Firewall (NGFW) that will provide Intrusion Prevention Service (IPS). A CrowdStrike product can be used for Intrusion Detection System (IDS). Monitoring network traffic and prevent potential threats can be accomplished with Paessler PRTG network monitor. The IDS/IPS can be tested by simulating web application attacks and verifying alert generation. Blocking mode will be enabled and confirmed that offensive IP addresses are blocked. Basic firewall rules will be configured and internet access restricted for client PC’s.

I propose a comprehensive approach to securing your network by installing and configuring a Next-Generation Firewall (NGFW) using pfSense (or OPNsense) in a virtualized environment, ensuring internet access control, traffic shaping, and a captive portal setup. Additionally, I'll integrate pfBlocker-NG for enhanced security and configure a Virtual IP for NAT. For the second assignment, I will deploy an IDS/IPS using Snort, Suricata, or Zeek, closely monitoring network traffic to detect and prevent threats. This will include testing with simulated attacks, customizing signatures, and exploring blocking modes to ensure full protection.
