With the threats of cyber terrorism and corporate espionage increasing, the need for trained network security professionals continues to grow. This book describes penetration-testing tools and techniques that ethical hackers and security testers use to protect computer networks. This book offers a structured knowledge base for preparing security professionals to discover vulnerabilities and recommend solutions for tightening network security and protecting data from potential attackers.
Given the content of the text, I would expect this to be an introductory book, not a "hands-on" guide. Over half of the so-called hands-on activities are simply reading and summarizing articles. There are better free resources online than this book that costs nearly $100.
Out of date and pretty much useless. You would learn more network security by studying network protocols and generic 'best practices'. The only redeeming fact about the book is that it mentions, albeit briefly, how to port scan and enumerate hosts.
