Security & Cyber Defense Challenges
Security & Cyber Defense challenges put you inside the work of protecting systems from real attack. You'll build skills around the CIA triad, authentication, identity & access management and network security, and learn to work the OWASP Top 10 and run vulnerability scanning the way defenders do.
From there you'll tackle the harder edges — threat modeling, the MITRE ATT&CK framework, SIEM operations and incident response — moving into cyber risk management, Zero Trust architecture and red team operations. Each challenge you solve earns a verified credential you can share with recruiters.
