Overview What You Will Learn Curriculum Instructor

Course Overview

Computer networks are the foundation of today's digital world, connecting users, devices, applications, and cloud services across local and global environments. Understanding how networks operate and how they can be secured is essential for IT professionals, cybersecurity practitioners, and anyone responsible for managing or protecting networked systems. This course builds a strong foundation in networking while introducing the core principles of network security.

This course begins with the fundamentals of computer networks, including network topologies, categories, devices, transmission media, the ISO/OSI model, and the TCP/IP protocol suite. You will then explore wireless networking technologies, network security principles, firewall deployment, honeypots, intrusion detection and prevention systems (IDS/IPS), wireless security protocols, physical security, incident handling, and core cybersecurity concepts such as the CIA triad, risk management, network attacks, and security best practices.

By the end of this course, you will understand networking fundamentals and be able to apply practical techniques to secure modern computer networks against common threats.
