Description

This learning path is a deep dive into Linux security and provides a comprehensive overview of the key areas that you need to know to secure your Linux systems!

We start by taking a look at Linux security in general before moving on to physical security and the countermeasures you can employ to protect your hardware. From there, we look at authentication systems and the various account types on a Linux system, and how to secure each one. You'll also learn how to enforce strong passwords and manage account and password expirations.

In the networking section, you'll learn how to secure network services that run on Linux systems. You'll also learn how the local firewall works in Linux and how to configure it. We'll cover file system security and how permissions work in detail, including special modes, file attributes, and ACLs. You'll also learn what rootkits are, how to detect them, and how to remove them.

This learning path also includes several security resources you can use to continue your security education and stay on top of the latest security issues for your Linux distribution.
