Deep Dive: Building Cybersecure-X Physical CTF

# Architecting Cybersecure-X Building a physical network CTF requires more than just software; it's about simulating real-world infrastructure. In this project, we focused on three core pillars: ## 1. SCADA Simulation We utilized specialized industrial protocols to simulate a power grid control system. Any breach in the network would have physical visual feedback. ## 2. DMZ Implementation The Demilitarized Zone (DMZ) was built to teach participants about layered defense. ```bash # Simulating a basic firewall rule for DMZ iptables -A FORWARD -i eth0 -o eth1 -p tcp --dport 80 -j ACCEPT iptables -A FORWARD -i eth0 -o eth1 -m state --state ESTABLISHED,RELATED -j ACCEPT ``` ## 3. The Physical Aspect Participants had to physically interact with nodes, making it a unique "on-device" experience. Stay tuned for more updates on the upcoming version!
