More About the Author

Chey Cobb became interested in computer security when personal computers began showing up in the workplace in the late 1980s. At that time, the biggest concern of employers was keeping employees from bringing infected floppy disks into the office. By the mid-nineties the cost of RAM chips soared and rivaled the price of gold. Still, it was difficult to convince people that computer theft and hacking would soon become common threats. As the implementation of computer networks began to increase, so did the number of threats and vulnerabilities. Chey became an expert in firewalls, anti-virus, and intrusion detection, and consulted with business owners on how to create a layered approach to computer and network security. She also implemented passive training programs for employees, primarily utilizing social engineering, to increase their awareness of potential vulnerabilities and how to respond to attacks.

Chey worked for the National Computer Security Association (NCSA), who created the first programs to certify anti-virus programs and firewalls. As businesses increasingly began connecting to the Internet (in the 1990s), Chey was one of the initially few who recognized that web servers introduced train-sized holes into a company's network. She correctly identified new areas of attack that exploited the inherent "openness" of a web server's architecture. Chey began writing about computer security for trade publications at this time and conducting seminars to increase awareness and to educate on effective security programs and policies.

While working in the private sector, Chey caught the eye of those in Washington, and she soon began working with government intelligence agencies. She created secure web platforms and applications and later went on to be in charge of security for one of the world's most sensitive and important networks. She also helped create cross-agency information security policies for the DoD and intelligence agencies and was instrumental in creating one of the first emergency response programs within a Top Secret agency.

After she left government work, she began writing and teaching more, with the intent to increase awareness of common threats and vulnerabilities, and advise people on effective network security without adversely affecting productivity. She taught briefly at Norwich University in their Masters Degree program for Information Assurance. Chey is currently retired and living on the West Coast and enjoys watching the Navy SEALs recruits running though their exercises on nearby beaches.

I bought this Network Security for Dummies after spending two frustrating hours in a large bookstore looking at one security text after another and finding that they were all written for people who already know a lot about networks. I suppose the assumption is that you won't get into network security until you have experience running a network, but the small company where I work only just set up a network and we need security right away. We can't afford to pay someone to run the network or be in charge of security. To my relief, the author of Network Security for Dummies understands this. It is obvious that she is just as knowledgeable about protecting networks as the authors of the other books I looked at (I was pretty amazed at what I found when I searched the web for the NRO, which the cover says is where she used to work). But she has taken the time to explain things to those of us who don't live and breathe computers. And she does so without talking down to you. At work we have already used some of the techniques she suggests and I feel confident we can make our network a lot more secure than it was, without spending a lot of money, but with the added advantage of really understanding what we are doing.

This is absolutely the best book I've ever read about networks and security. It isn't a "dumb" book and it's not too simplistic, either. It's perfect for network people who are supposed to be doing security, but don't know where to start. There's lots of stuff in there I never thought about - like your computers being used to attack other computers. There are a lot of checklists and hints to help out companies who don't have a computer security expert on board. Thank you, Ms Cobb for writing such a neat book

I really liked this book! All the others I picked up on the subject turned out to be about hacking and/or were deeply technical. This book hits just the right balance of basic explanations (without being condescending) and intro-level technical advice. My wireless network was wide open and I didn't realize it until I read this book. I also know how to secure my computers with security patches - which always seemed like a black magic to me before. This writer really knows her stuff! I hope she does more books!

This book is a great place to find everything in one place. This is the first book I've ever read that gives you step by step instructions on securing servers. Most of the other books I've read tell you to do it, but they don't tell you how. I especially liked the chapter on wireless networks. My company just installed one and we didn't know that it was open to the public. I've heard that a lot of computer security has to do with basic rules or common sense, but I've never seen it put all in one place and explained so well before.

If you have a fundamental understanding of how networks operate, and want an overview of various IT security concepts, this book may be for you. Unfortunately, much of it is out of date. For example, the operating systems ,along with their attendant problems, the book addresses are primarily Windows XP and Windows NT...yes, NT. So when the author spends a chapter talking about plugging the specific security holes in those particular operating systems, its almost wasted time.

With that said, they go beyond OS's and in depth about other hardware and software involved in IT sec, most of which is still relevant. They cover firewalls, routers, virus and endpoint protection, and more.

With what I've learned from this book, I'm ready to go deeper into the subject, which is all I was expecting from this book anyway. So in that regard, it was exactly what I was looking for - I just wish they could have updated the edition from 2002. From the listing it looked like it had been updated in 2011, but apparently the update didn't cover enough material.

Very General information. I was looking for more specific information about security. This is more of an overview. Not very helpful.

Pretty basic and clearly written over a decade ago. Wile it has been somewhat updated, the references to Windows 95 throughout the text made it feel ancient.

This book explains network security in a way that's easy to understand. However, I sometimes felt that some of the concepts discussed were a bit outdated. I think some parts may need a bit of refreshing.
