The logical security architecture develops more detail to flesh out the bones of the conceptual framework that you have developed at the second layer of the security architecture model. The logical layer is largely concerned with the functional view of security, defining a comprehensive set of functional requirements. It does not at this stage pay attention to the security mechanisms that will be used to deliver those functions – these are part of the physical security architecture at the next layer down.
In this chapter you will learn about:
- An information architecture model that distinguishes between knowledge, information and data;
- The differing needs for securing static information and dynamic information; ...
