What you'll learn

Access control mistakes—overly permissive files, forgotten sudo grants, weak password policies—are among the most common ways Linux systems get compromised. In this course, User, Group, and Permission Management in Ubuntu Linux, you'll gain the ability to manage the full access control lifecycle on an Ubuntu system. First, you'll explore how to create, modify, and remove user accounts and groups, and interpret the system files behind them. Next, you'll discover how standard Unix permissions and special permission bits govern what users and processes can actually do to files and directories. Finally, you'll learn how to configure sudo access, enforce password policies, and apply Access Control Lists for more granular control than standard permissions allow. When you're finished with this course, you'll have the skills and knowledge of Ubuntu access control needed to manage users, permissions, and privileged access securely in a professional environment.
