Security continues to be the predominant concern for any organization that is either on the Internet now or considering it. Nary a week passes where there isn't some new report of hackers breaking into computer systems at some government agency, or trashing some Fortune 500 company's Web site, or even stealing user passwords and credit card numbers. In June 1997, this book's first edition immediately shot to the top of several computer security bestseller lists. While undoubtedly some bought the book to learn how to hack, it turns out that the book's most enthusiastic fans were computer security managers who appreciated the book's comprehensive coverage and clear, to-the-point descriptions of the most common techniques hackers use to penetrate systems. The hacking community, however, hasn't stood still. This thoroughly updated edition discusses the hundreds of new computer system holes that have been discovered over the course of the past year, and covers the latest hacker techniques.
