Linux Kernel and Loadable Modules for Penetration Testing

Security professionals and penetration testers must understand the core operating system to identify hidden vulnerabilities and secure system entry points. This text-based course guides you through the foundational concepts of the Linux kernel and its loadable kernel modules (LKMs), showing you how to inspect, manage, and secure these vital components during security assessments. You will transition from understanding basic kernel architecture to confidently auditing kernel configurations and recognizing potential module-based exploits. What you'll learn: Understand the core architecture of the Linux kernel and how loadable modules function; Query and analyze loaded modules using standard command-line tools in Kali Linux; Configure and secure kernel parameters to prevent common privilege escalation techniques; Practice auditing kernel module loading policies to identify security misconfigurations; Apply kernel-level knowledge to enhance web application penetration testing environments. The course begins with clear definitions of kernel space versus user space, moving systematically through module management commands, security auditing techniques, and modern kernel hardening principles. This course is designed for aspiring penetration testers, system administrators, and security enthusiasts who want a solid foundation in Linux internals, with no prior kernel programming experience required.
