In my latest role, I spearheaded a comprehensive network infrastructure overhaul where I architected and deployed a sophisticated network configuration using pfSense as our firewall and router solution. Recognizing the need for robust security and efficient network traffic management, I designed a system segmented into multiple subnets, VLANs, and VPNs to optimize performance and enhance security.
I started by carefully planning our network segmentation strategy to align with our business requirements and security policies. By creating multiple subnets, I ensured that different departments had their own dedicated network segments, isolating traffic and minimizing the potential impact of security breaches.
Implementing VLANs was a critical step in this setup. It allowed us to enforce strict network access controls and segregate traffic types, which is particularly important in preventing lateral movement within the network in case of intrusions. This setup also simplified the management of our network policies and provided the flexibility to scale as needed without overhauling the physical infrastructure.
I also configured VPNs to secure remote access, enabling our workforce to connect to the corporate network safely from any location. This was vital in maintaining business continuity, especially with the shift to remote work. The VPN setup was not only about encryption and secure tunnels but also about integrating with our authentication systems to ensure that only authorized personnel had access.
Beyond these, I implemented additional pfSense features such as traffic shaping for bandwidth management, intrusion detection systems, and detailed logging to monitor network health and security. I configured redundant VPNs for failover to guarantee uptime and crafted intricate firewall rules to meticulously control the traffic flow.
My approach was methodical and security-centric, ensuring that each change was thoroughly tested in a controlled environment before deployment. This meticulous planning and execution resulted in a robust, scalable network infrastructure that supported the company’s operations securely and efficiently.
This project is a testament to my ability to design and execute complex network configurations that align with modern security best practices and operational requirements. It underscores my commitment to creating resilient IT infrastructures that not only meet today’s demands but are also prepared for future challenges.
