Product Description
There are hundreds--if not thousands--of techniques used to compromise both Windows and Unix-based systems. Malicious code and new exploit scripts are released on a daily basis, and each evolution becomes more and more sophisticated. Keeping up with the myriad of systems used by hackers in the wild is a formidable task, and scrambling to patch each potential vulnerability or address each new attack one-by-one is a bit like emptying the Atlantic with paper cup. If you're a network administrator, the pressure is on you to defend your systems from attack. But short of devoting your life to becoming a security expert, what can you do to ensure the safety of your mission critical systems? Where do you start? Using the steps laid out by professional security analysts and consultants to identify and assess risks, Network Security Assessment offers an efficient testing model that an administrator can adopt, refine, and reuse to create proactive defensive strategies to protect their systems from the threats that are out there, as well as those still being developed. This thorough and insightful guide covers offensive technologies by grouping and analyzing them at a higher level--from both an offensive and defensive standpoint--helping administrators design and deploy networks that are immune to offensive exploits, tools, and scripts. Network administrators who need to develop and implement a security assessment program will find everything they're looking for--a proven, expert-tested methodology on which to base their own comprehensive program--in this time-saving new book.

It doesn't matter whether they are windows or *nix. Numerous exploits and malicious codes are released every day. Researchers published new vulnerabilities everyday online. So, the need arises to secure your perimeter from hackers and crackers. There are numerous freeware and commercial products available for this purpose. The book "Network Security Assessment" covers the same issue in detail and describes how you can secure your perimeter. It describes numerous tools and shows how one can use these to explore vulnerabilities and misconfigurations in your network. It offers proactive defence measures to secure your network. "Network Security Assessment" provides a good framework for anyone who is involved in network security. I've read a number of security books. But, I think this book is a text book for security engineers. The book starts from the basic concepts of network enumeration using basic scanning tools like nmap and discuss many server issues like http/ftp/smtp server etc. It explains systematic use of tools and techniques for penetration testing. I strongly recommend this book for security engg and penetration testers. Comment Comment | Permalink | Was this review helpful to you?

Shaikh (Swindon, Wilts, UK) - See all my reviews (REAL NAME)    This review is from: Network Security Assessment: Know Your Network (Paperback) This book introduces the tools and techniques used for evaluating the security of networks and services. It aims to provide the readers with tactical and technical knowledge to determine how secure a network is by attempting to probe and exploit it. It serves as an excellent in-depth technical resource for those who continuously strive to protect their networks. The first chapter sets the scene and gives an overview of the network security assessment methodology. The following chapter familiarises the reader with tools and software that are used at various stages of the book. The author then takes the reader on an extensive technical journey, tackling every aspect of a network to highlight potential weaknesses and vulnerabilities that may exist and ways to determine them. From chapter to chapter, the author covers it all, including network enumeration, web services and applications, database and email services, VPNs, various Windows and Unix specific services and more. At the end of every chapter, a section on appropriate countermeasures is added to discuss means to protect systems from the vulnerabilities uncovered in the chapter. A few chapters worthy of mention include chapter 4, which is one of the best surveys on network scanning and probing techniques I have come across. It covers the various characteristics of IP, ICMP, TCP and UDP protocols used to gather information about networked hosts and services. Scans and probes are discussed in relevant and clear detail along with the various tools available to launch them. Chapter 14 provides a very thorough examination of memory manipulation attacks that are launched at the application level. Chapter 15 introduces Nessus, a popular vulnerability scanning tool, and serves as a good user guide to install and effectively use the tool. What I really miss in this book is a final concluding chapter. A discussion on the overall strategy needed to carry out a rigorous and effective assessment, particularly for medium to large corporate networks where such an exercise is most needed, could have been very useful. Network security assessment requires a considerable depth of technical knowledge and an aptitude for such activity. This book allows the reader to gain both. It is up-to-date and detail oriented, and is good value for money. Comment Comment | Permalink | Was this review helpful to you?
