EC-Council Certified Network Defender CND Training. The Certified Network Defender (CND) is a vendor-neutral, hands-on training program that provides comprehensive network security certification. The program is built on a skills-based, lab-intensive approach grounded in the security education frameworks developed by the National Infocomm Competency Framework (NICF) and the National Initiative for Cybersecurity Education (NICE).

It aligns with global job roles and the Department of Defense (DoD) roles for system and network administrators. The course equips network administrators with the skills to assess parts of an organization for security vulnerabilities and implement strategies to reduce, prevent, and manage risks.
