Certified Network Defender (CND)

To mitigate cyber breaches, organizations rely on network administrators who protect, detect and respond to the threats on their networks. In this 100% online course, you will learn the concepts and practices network defenders use. Key topics include computer network and defense fundamentals, wireless network defense, network traffic monitoring, and data backup and recovery. Upon successful completion, you will be prepared to take and pass the Certified Network Defender (CND) exam, a credential that validates your ability to provide continuity of operations during attacks.


Network defenders focus on the operations and processes involved in network defense. They target maintaining infrastructure in a system. A day in the life of a network defender could include testing a network for weaknesses, installing and designing security programs, and evaluating and protecting networks.

Some network defender skills include resiliency and the ability to maintain the flow of operations during attacks and the ability to develop strategies for secure configuration of devices. Network defenders use these skills for the purpose of detecting and preventing intrusions and damage.

To mitigate cyber breaches, many organizations rely on network engineers who protect, detect and respond to the threats on their networks. A certification such as the Certified Network Defender (CND) validates your ability to provide continuity of operations during attacks.
