Laboratory Exercise: Cyber Basics - Introduction to the Linux Terminal and Understanding Directories

This laboratory exercise will provide a fundamental understanding of the Linux Terminal (also referred to as the command-line), a powerful tool for all cyber security professionals. The terminal allows a user to manipulate files, create users, and run terminal programs to perform certain tasks.

For the purposes of this lab, we will be focusing on the Linux filesystem and directories.

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.

If you are using the Virginia Cyber Range Kali Linux VM, 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.
