1. Introduction to Assessing Network Vulnerabilities

This chapter introduces some basic security concepts, such as what security really is. It also starts the discussion of risk assessment as a process. Risk is all around us, and good Information Technology (IT) governance requires us to assess its potential dangers. Finally, this chapter will provide an overview of the network vulnerability assessment. Understanding how the network vulnerability assessment fits into the overall security program will help as we go through the entire process in subsequent chapters.
