The Role of CIA

The three fundamental items upon which security is based together are known as the CIA triad (see Figure 3.1). You will see these concepts presented throughout this book.

Figure 3.1. CIA security triad.

Which one of these three is most important? Well, that depends. They are all important, but organizations are unique. Different elements of the CIA triad will take the lead in different companies. For example, your local bank might consider integrity the most important, but an organization that does data processing might see availability as the primary concern.
