Information Assurance

7.1. Introduction

Our societal infrastructure, such as defense, emergency services, and telecommunications, has become dependent on distributed networking systems. These systems typically consist of components of varying quality and are integrated to provide essential services for the end users. This pervasive societal dependency on networks magnifies the consequences of failures and amplifies the vital importance of ensuring their survivability. As a result, methods for achieving system survivability are receiving increasing attention [1, 2]. At the same time, public awareness of security is growing with the implications of computer systems and their applications operating in the unbounded environment of the global information grid. Thus, network ...
