Look inside

Linux PAM (Pluggable Authentication Modules) is a suite of libraries for authenticating users of applications and services in a Linux system or server. Essentially, PAM centralizes the process of authentication for myriad programs. It is a powerful tool, but it’s crucial to understand how it works, as it affects the security of much of your system.

Whether you use Linux at home, or at work as a system administrator, knowing at least the basics of PAM will help you keep your system secure and functional. In this course, we start with an overview of what PAM does and why it is important. Then we then look at the PAM file configuration formats, module interfaces, and how it communicates with the server.

Homework, handouts, and a quiz reinforce your learning.
