All operating systems have a set of "kernel" code that contains the basic core of the operating system. The kernel code allows the user to control the hardware and many of the applications used by the computer. A number of "security kernels" have been designed that are intended to protect the operating system from unauthorized modification as well as controlling access to the OS and ensuring that the operating system functions correctly. One obvious disadvantage to deploying an OS with a security kernel is that the security code incurs additional processing overhead. What other disadvantages and advantages might be involved? If considered as a client OS to be deployed across an organization, under what circumstances would the disadvantages of a security kernel be justified? Why?
