Chapter 1. Fundamentals of IT security<br />

In this chapter, we <strong>cover</strong> the necessary background knowledge for this Redbook.<br />

This will help the reader comprehend the terms and topics presented later on<br />

and ensure, as well, a thorough understanding of the terminology used<br />

throughout the redbook.<br />

We define both security and IT security. We look at some interesting studies and<br />

statistics in order to show the current trends in security, and we also look at<br />

established standards.<br />

This chapter is geared towards a wide range of readers:<br />

► People who are new to the field of IT security and want to have a place to<br />

begin understanding IT security and all this represents<br />

► People who already have IT security experience and wish to have a quick<br />

refresher<br />

► People who fall somewhere in between those two categories, and above all,<br />

who like to read their <strong>Redbooks</strong> from beginning to end.<br />

While it is possible to skip this chapter and come back to it later, we strongly<br />

encourage the reader to take a few minutes to brush up on the IT security<br />

fundamentals presented here.<br />
