It seems that the title of this book—Network Security: A Beginner's Guide—defines what it is about pretty well. But this book is not just a beginner’s guide. In writing this book, I attempted to pick out the issues that have confronted me on a day-to-day basis when working as a security professional and a consultant. Most of these issues caused me much consternation over the years and it would have been very helpful for me to have had all of this information at my fingertips.
Security continues to be an issue for organizations. Not only are we hearing about the successful penetration of web sites and organizations, but we also have new laws and regulations that affect the protection of information. In response to these issues, more and more vendors are appearing with tools that offer some protection. After looking at all of this information, you might think that the big issues in security can be solved with technology. Unfortunately, security issues are much more complex than that.
Basically, security is a people issue. No matter how much technology we throw at this problem, the best we can do is to make the job of the security professional a little easier. We will not solve the basic problem with technology, but we can manage the security problem through the dedicated application of well–thought-out security processes and
procedures. Hopefully, this book will provide you with the basic tools you will need to manage your security issues.
