Configure And Build Your Own Secure Linux Kernel One of the best ways to get a feeling for the Linux kernel internals and security features is to configure its settings and then compile it. Most GNU/Linux users and administrators use kernels configured and provided by the community (free and open source distributions) or corporate sponsors (e.g. Red Hat Enterprise Linux, SUSE Linux Enterprise, Canonical Ubuntu). One of the best ways to get a feeling for the Linux kernel internals and security features is to configure its settings and then compile it. Most GNU/Linux users and administrators use kernels configured and provided by the community (free and open source distributions) or corporate sponsors (e.g. Red Hat Enterprise Linux, SUSE Linux Enterprise, Canonical Ubuntu). The goal of the article is to give you an idea of how to configure a kernel with customized and/or fewer features, which will reduce the chances of an attacker breaking into your systems. For that purpose

Kernel Security In computing, the kernel is the main component of most computer operating systems; it is a bridge between applications and the actual data processing done at the hardware level. The kernel responsibilities include managing the system resources (the communication between hardware and software components) (1) Operating system tasks are done differently by different kernels, depending on their design and implementation. While monolithic kernels execute all the operating system code in the same address space to increase the performance of the system, microkernels run most of the operating system services in user space as servers, aiming to improve maintainability and modularity of the operating system . A range of possibilities exists between these two extremes.(Figure 1). Figure 1. Kernel role in a computer This paper introduces concepts of the security kernels as well as two examples of them: Kernelized Security Operating System and Honeywell Secure Communi
