Fundamentals of Linux Security for System Administrators teaches students basic Linux command line usage and filesystem structure, how to configure, evaluate and troubleshoot common management services used on today’s Linux systems, and well as how to configure and test a Linux-based firewall. Linux System Administrators are often responsible for managing systems containing critical or sensitive data and infrastructure. The ability to securely and effectively manage Linux systems is paramount to the System Administrator job role. Completion of this module will prepare students to handle the basic requisite tasks associated with configuring, managing and troubleshooting Linux management tools, services and firewalls.
In order for system administrators to effectively design secure systems, they must have a solid understanding of the Linux command line and file system, and how processes such as authorization, authentication, encryption, and service hardening work across a variety of operating systems. In addition, system administrators should have a strong understanding of common Linux ports, services, and how to control access to ports and services via firewalls.
