Chapter 2. Knowing Why You Want NAC
In This Chapter
Understanding what motivates NAC deployment
Addressing access control and network security issues with NAC
Knowing the risks associated with not deploying NAC
You know that NAC is the acronym for network access control, but you may be wondering why someone's network access needs to be controlled. Like with any business operation, technological and market drivers influence the need for network access control or limitations. Also, the number of network users, the information they use, and the type of work they do affect the frequency and level of access they need.
In this chapter, we explain some of the key reasons why companies need to control access to their networks. We also briefly discuss ways for companies to ease into a NAC solution, as well as why some companies may choose not to control access to their network and the possible ramifications of that decision.
