Analyzing kernel vulnerabilities requires an environment to carry out the reproduction of exploits. Being able to quickly and securely stage an operating system is essential. In this course, you'll explore virtual environments and stage systems using QEMU. You'll develop an approach to setting up virtual environments for the Linux kernel, complete with network support. You'll install Linux kernels by version and compile Linux kernels from scratch. Next, you'll investigate architectural considerations, emulate architectures in QEMU, and gather system info from your staging environment. Finally, you'll examine vulnerability considerations that might affect the virtual environment itself and identify safeguards for protecting your computing environments when carrying out exploit analysis. By the end of this course, you'll be able to launch an instance of Alpine Linux, configure networking options, and emulate an Alpine Linux ARM variant within a QEMU environment.
