Linux Kernel and Loadable Modules

Learn about the underlying system processes that power the Linux operating system.

Introduction to the kernel

The kernel is the central engine that controls everything in the operating system. Administrative privileges can change how the system works, looks, and feels in operation. This means that an unauthorized person can change any of the given operations within the system.

A pentester needs to be very careful when accessing the kernel because any wrong change in how the operating system works would result in crashing a web server or the operating system. Keeping this in mind, we’ll now examine the modules of the kernel and how to manage them.
