LABORATORY EXERCISE: CYBER BASICS - Introduction to Networking

In this lesson, the student will learn the fundamentals of networking. The student will use the Linux operating system as a tool to understand networking concepts. By now, the student should understand the Internet, ethernet connections, and Wi-Fi. By the end of this lesson, the student should understand how machines communicate with each other in a network.

Faculty Instructions

Resources required

This exercise requires a VirtualBox Kali Linux Virtual Machine running on a computer (laptop) or a Kali Linux VM running in the Virginia Cyber Range. It is HIGHLY recommended faculty use the Virginia Cyber Range “Cyber Basics (2018)” environment.

If you are using the “Cyber Basics (2018)” environment or a standalone Kali Linux VM (2018) in the Virginia Cyber Range, this lab exercise requires an account on The Range.  To sign up for an account on The Range, please visit our Sign-Up page.  Your students will also require an account on the Virginia Cyber Range; this will be explained in the setup of your course.

Virtual Environment: This exercise uses a single Kali Linux virtual machine.
