In this course I will teach you how a kernel security works inside linux operating system.This course is for educational purpose don't use these skills for offensive purpose. Use these skills to understand the different aspects of rootkits inside an operating system for defensive purpose.

In this course I will start from the very basics of kernel and will go into indepth adventure of rootkits. So you will feel very curious day by day by following this course.

If you are feeling that you don't know about kernel at all don't worry I have made this course such a way that you will not stuck at any point because I have started from very basics as to keep in mind that the learner does'nt know about kernel at all.

What are kernel rootkits:

• A kernel rootkit is a type of malicious software that is designed to operate at the kernel level of an operating system. It is designed to remain hidden and to operate without the knowledge or consent of the user.

• Kernel rootkits are very dangerous and can be very difficult to detect and remove, because they operate at such a low level of the operating system.

• They have full access to control all the system resources, including memory, I/O, and system calls, and can intercept and modify system calls to hide their own actions.

• Kernel rootkits can be used for a variety of malicious purposes, such as allowing an attacker to gain unauthorized access to a system, to steal sensitive information, or to disrupt the operation of the system.

• They can also be used to create a "backdoor" into a system, allowing an attacker to regain access at a later time.

Learning about kernel security and how they work can help individuals and organizations to better understand and defend against these types of threats.

For example, understanding the techniques and tactics used by rootkits can help security professionals to design more effective defenses and to identify and mitigate rootkit infections. It can also help individuals to make more informed decisions about the security measures they use to protect their own systems and data.
