In Halting the Hacker, a leading Fortune 500 security consultant shows you the approaches and techniques hackers use to gain access, privileges and control of your UNIX system -- and what to do about it. You'll learn to look at your system the way a hacker does, identifying potential vulnerabilities. Discover specific countermeasures you can take now. Even more important, this book shows how to recognize and respond to future security concerns -- before they become catastrophes. Halting the Hacker explains how hackers transform minor oversights into major security breaches; how they cover their tracks while leaving back doors into your system; and how to protect your system against disgruntled or dishonest insiders. You'll also learn how to detect break-ins -- and what to do if one occurs. Halting the Hacker even includes an exclusive CD-ROM software library of tools to detect and eliminate security problems, and a comprehensive information archive on security and hacker-related topics. This is an invaluable resource for all system administrators, managers and IS professionals.
