Linux & Unix User Management & Security Using WSL

Managing users, groups, and permissions is at the core of every secure Linux or Unix system. Without proper user management and security controls, even the most powerful servers can quickly become vulnerable. This course, Linux & Unix User Management & Security, is designed to equip you with the practical skills and knowledge to confidently administer user accounts, enforce security policies, and manage permissions in Linux and Unix environments.

We start by making sure your environment is ready. If you are using Windows, you’ll learn how to set up Linux easily through Windows Subsystem for Linux (WSL), ensuring you can follow along without needing a dedicated server. You will become comfortable with the Linux prompt and learn how the shell provides access to powerful administrative commands.

Once your environment is ready, we dive into the essentials of user management. You will discover the different types of user accounts in Linux and Unix—root, system, and regular users—and understand their roles. From there, you will learn how to create new user accounts interactively and non-interactively, manage group memberships, and organize users into groups for efficient access control.

Security is the backbone of this course. You’ll practice locking and unlocking accounts, deleting users safely, and setting password policies to enforce best practices across your system. Beyond accounts, we’ll cover the Linux/Unix permissions model, where you’ll learn how to view and modify file and directory access rights. By mastering commands such as chmod, chown, and ls -l, you’ll gain the ability to protect sensitive resources and ensure that only the right users have access.

To reinforce learning, every concept is paired with hands-on demonstrations and practical exercises. You won’t just memorize commands—you’ll use them in real-world scenarios. By the end of the course, you’ll not only understand how user accounts and permissions work but also how to apply them to secure and manage a Linux or Unix system effectively.

This course is perfect for beginners who want to build a strong foundation in Linux administration, as well as IT professionals, developers, or aspiring system administrators who need practical skills in managing users and securing systems.
