After you ve put forth the effort to harden your network, however, the last thing you want is to see all of your effort and work fail, and yet many companies find themselves in this situation.

The inevitable question is why ? In Part IV we seek answers to that question, and by doing so provide you with tools and information that you need to ensure that you can succeed at hardening your network infrastructure.
In this section we shift our focus from some of the technical aspects of hardening your network and look at some of the soft skills involved.

In fact, this chapter can be key to ensuring the success or failure of your infrastructure hardening efforts, because it looks at the two things that are most likely to contribute to the success or failure of efforts: setting the appropriate expectations and getting the money needed to undertake the effort.
Throughout this chapter, it may seem like some of the information is directed more at management personnel. That isn t quite correct. While it is critical that management understands and supports the concepts and recommendations put forth, the technical folks must also understand the impact that they can have with the user community through their words and actions. Even those ideas that are key to management are important for the technical folks to be aware of and understand.
