Question
Suppose that Fred Foolish, a colleague of yours, says "I have heard that the security of an operating system is built on the hardware mechanism that separates user mode from kernel mode. This means that an attack that succeeds against one operating system must have broken the hardware mechanism, and therefore the same attack will work against any other operating system on the same type of machine. Thus there can't be any reason to believe that one operating system is more secure than any other." Write a discussion that explains to Fred why his argument is invalid.Explanation / Answer
This is not necessarily true since the architecture of the operating system can make it easier or harder for a person with malicious intent to enter the kernel. While the hardware remains the same either way, the software(operating system), can have an effect on the amount of hacking that can be done. Poorly coded operating systems can have intentional or unintentional backdoor access which allow the hacker to get into the kernel mode from user mode easily or bypass user mode entirely.
