Kernel-Mode Debugging Concepts
Get an introduction to the principles of kernel-mode debugging for analyzing operating system components and drivers.
Intro to Kernel Debugging
Welcome to Kernel-Mode Debugging Concepts! In this lesson, we'll explore how to analyze the heart of an operating system.
Unlike user-mode debugging, which focuses on individual applications, kernel debugging lets us peek into the operating system's core, including drivers and critical system components.
Kernel vs. User Mode
Operating systems operate in different privilege levels. The two main ones are kernel mode (Ring 0) and user mode (Ring 3).
- User Mode: Where regular applications run. They have limited access to hardware and memory, relying on the OS for critical tasks.
- Kernel Mode: Where the operating system kernel and device drivers run. It has full, unrestricted access to hardware and memory.
Kernel debugging allows us to analyze code running with these elevated privileges.
