CyberPatriot’s National Youth Cyber Defense Competition challenges teams of high school and middle school students to find and fix cybersecurity vulnerabilities in virtual operating systems. Using a proprietary competition system, teams are scored on how secure they make the system. Top teams advance through the online round of competition, and the best of the best advance to the in-person National Finals Competition. Each team has two challenges during their six-hour competition period: Network Security Challenge: involves finding and fixing security vulnerabilities in Windows and Linux operating systems. Cisco Networking Challenge: consists of an online quiz and a virtual networking exercise based on specific training materials.
