Information security foundation, theories and future vision

The aim of this chapter is to establish some of the baseline principles and to show the breadth of the topic. Other chapters will then build upon this by exploring at least some of the issues in further depth. As will become apparent, there is not a single and simple way to look at security that easily captures all the various dimensions of interest. As such, much of this chapter is devoted to considering the issue from different angles, with the intention that by doing so a sufficiently comprehensive picture will ultimately have been presented to set the scene for the various discussions in later chapters.
