Synopsis

KEY BENEFIT: This text provides a practical survey of both the principles and practice of cryptography and network security. First, the basic issues to be addressed by a network security capability are explored through a tutorial and survey of cryptography and network security technology. Then, the practice of network security is explored via practical applications that have been implemented and are in use today. The book is suitable for self-study and so provides a solid and up-to-date tutorial. The book is also a comprehensive treatment of cryptography and network security and so is suitable as a reference.

Biography

William Stallings has made a unique contribution to understanding the broad sweep of technical developments in computer networking and computer architecture. He has authored 18 titles, and counting revised editions, a total of 35 books on various aspects of these subjects. In over 20 years in the field, he has been a technical contributor, technical manager, and an executive with several high-technology firms. Currently he is an independent consultant whose clients have included computer and networking manufacturers and customers, software development firms, and leading-edge government research institutions.

He has six times received the prize for best Computer Science and Engineering textbook of the year from the Textbook and Academic Authors Association.

Bill has designed and implemented both TCP/IP-based and OSI-based protocol suites on a variety of computers and operating systems, ranging from microcomputers to mainframes. As a consultant, he has advised government agencies, computer and software vendors, and major users on the design, selection, and use of networking software and products.

Dr. Stallings holds a Ph.D. from M.I.T. in Computer Science and a B.S. from Notre Dame in Electrical Engineering.

Cryptography and Network Securityby Anonymous

August 26, 2006: Stallings presents an updated education on cryptography. With a secondary emphasis on network security. In the cryptographic sections, there is a strong mathematical flavour. The narrative is not a high level, management-type discussion. It favours the professional mathematician and programmer, and ideally the intersection of these two skill sets. Unlike some other books on cryptography, here considerable space is also given to hash functions. These can sometimes be used as an alternative to a full encrypt/decrypt approach. If you are designing a system, you should ponder carefully whether a hashing approach might suffice. Usually if you only need to authenticate a message or item. Since, as the book relates, for all the complexity of the various hash algorithms, hashing is far simpler and faster than public key encryption. And there is no problem with key revocation. Another great simplification. One surprising feature of this 4th edition is that PKI is mentioned here, unlike earlier editions. PKI has been around long enough and is important enough that I would've thought the 3rd edition of the book would have covered it. The last sections of the book, on network and system security, are less mathematical. But to offset this, as it were, they require somewhat of a background in understanding the Internet Protocol and in the systems administration of a subnet of computers. Maybe the simplest advice to understand and implement is for a sysadmin to install and regularly run a password checker against your users' passwords.
