Chapter 13, Problem 13.5E

Explanation of Solution

Use of layered approach for asset protection:

In system architecture, protection is one of the fundamental issues and layered architecture is used to provide protection.

In layered architecture, the critical protected assets are present at lowest level in lowest level and they have layers of protection around them.

For example, in a patient record system, the critical assets that need to be protected are records of each individual patient.

An attacker has to penetrate three system layers in order to access and modify patients’ records and as protection increases layered approach improves security...
