In physical separation, different physical resources use different processes. Even though its implementation is easy, it is often expensive and inefficient. A scanner is an example of an object where physical separation for security. Different processes are involved in its usage, and for each process, the security level also changes. There is a need to ensure the scanner is secure from all access that is unrelated. It is at the physical level that the operating system is separated to show that for different objects,
