Overview
Security expertise for Linux systems is in high demand and will remain so for the foreseeable future. Master Linux kernel security to protect critical infrastructure and open doors to high-impact roles in cybersecurity, staying ahead in the rapidly growing cybersecurity field.
Skills Gained
The course covers the fundamentals of Linux kernel security, including memory protection, process management, system calls, and filesystem security. Students will learn about various security mechanisms in the Linux kernel, such as Mandatory Access Control (MAC), Linux Security Modules (LSM), and secureboot. Throughout the course, students will gain hands-on experience in securing both userspace and the Linux kernel through various security mechanisms.
Who Can Benefit
This course is designed for systems level programmers or kernel engineers who want to learn more about the security options provided by the Linux kernel, as well as userspace developers who want to learn more about Linux kernel security mitigations. Learners should know how to build a Linux kernel, write and use Linux kernel modules, as well as have basic Linux command line and system administration skills.
Prerequisites
