I believe The Craft of System Security is one of the best software security books on the market today. It has not only breadth, but depth, covering topics ranging from cryptography, networking, and operating systems--to the Web, computer-human interaction, and how to improve the security of software systems by improving hardware. Bottom line, this book should be required reading for all who plan to call themselves security practitioners, and an invaluable part of every universitys computer science curriculum. --Edward Bonver, CISSP, Senior Software QA Engineer, Product Security, Symantec Corporation Heres to a fun, exciting read: a unique book chock-full of practical examples of the uses and the misuses of computer security. I expect that it will motivate a good number of college students to want to learn more about the field, at the same time that it will satisfy the more experienced professional. --L. Felipe Perrone, Department of Computer Science, Bucknell University Whether youre a security practitioner, developer, manager, or administrator, this book will give you the deep understanding necessary to meet todays security challenges--and anticipate tomorrows. Unlike most books, The Craft of System Security doesnt just review the modern security practitioners toolkit: It explains why each tool exists, and discusses how to use it to solve real problems.
