Course Description

Course Overview

The Certified Network Defender (CND) course is designed to equip individuals with the knowledge and skills necessary to defend and secure computer networks against cyber threats. This course focuses on network security technologies, policies, and procedures to establish a strong defense posture.  The CND certification validates the expertise of network administrators, security professionals, and other individuals responsible for maintaining network integrity. With the CND certification, participtant will gain a comprehensive understanding of data transfer, network and software technologies, enabling them to comprehend network operations and analyze relevant material.


To enroll in the CND course, individuals should have a basic understanding of networking concepts, including TCP/IP protocols, network devices, and network administration. Familiarity with operating systems such as Windows and Linux is recommended. A foundational knowledge of cybersecurity principles and practices will also be beneficial.


The CND course utilizes a combination of theoretical lectures, hands-on lab exercises, and practical demonstrations to provide a comprehensive learning experience. Students will gain knowledge through interactive sessions and discussions, and they will have the opportunity to apply their learning in virtual lab environments. The course emphasizes practical skills development and real-world application.
