 Rather than jump directly into what you need to know for the CSPFA 642-521 examination, this chapter presents some background information about network security and its integral role in business today. You need to understand this information because it is the basis for CCSP Certification and is a common theme throughout the five CCSP certification exams.The term network security defines an extremely broad range of very complex subjects. To understand the individual subjects and how they relate to each other, it is important for you first to look at the "big picture" and get an understanding of the importance of the entire concept. Much of an organization's assets consist of data and computer resources that are interconnected and must be protected from unauthorized access. There are many different ways to ensure that network assets are adequately protected. The key is to correctly balance the business need with the requirement for security. |
