Chapter 1

What is Information Security?

In this chapter, we cover some of the most basic concepts of information security. Information security is vital in an era in which data regarding countless individuals and organizations is stored in a variety of computer systems, often not under our direct control. We talk about the diametrically opposing concepts of security and productivity, models that are helpful in discussing security concepts, such as the confidentiality, integrity, and availability (CIA) triad and the Parkerian hexad, as well as the basic concepts of risk and controls to mitigate it. Lastly, we cover defense in depth and its place in the information security world.
