Maximum Security: Hacker's Guide to Protecting Your Internet Site and Network

Hacking and cracking are activities that generate intense public interest. Stories of hacked servers and downed Internet providers appear regularly in national news. Consequently, publishers are in a race to deliver books on these subjects. To its credit, the publishing community has not failed in this resolve. Security books appear on shelves in ever-increasing numbers. However, the public remains wary. Consumers recognize driving commercialism when they see it, and are understandably suspicious of books such as this one. They need only browse the shelves of their local bookstore to accurately assess the situation.

Books about Internet security are common (firewall technology seems to dominate the subject list). In such books, the information is often sparse, confined to a narrow range of products. Authors typically include full-text reproductions of stale, dated documents that are readily available on the Net. This poses a problem, mainly because such texts are impractical. Experienced readers are already aware of these reference sources, and inexperienced ones are poorly served by them. Hence, consumers know that they might get little bang for their buck. Because of this trend, Internet security books have sold poorly at America's neighborhood bookstores.

Another reason that such books sell poorly is this: The public erroneously believes that to hack or crack, you must first be a genius or a UNIX guru. Neither is true, though admittedly, certain exploits require advanced knowledge of the target's operating system. However, these exploits can now be simplified through utilities that are available for a wide range of platforms. Despite the availability of such programs, however, the public remains mystified by hacking and cracking, and therefore, reticent to spend forty dollars for a hacking book.

So, at the outset, Sams.net embarked on a rather unusual journey in publishing this book. The Sams.net imprint occupies a place of authority within the field. Better than two thirds of all information professionals I know have purchased at least one Sams.net product. For that reason, this book represented to them a special situation.

Hacking, cracking, and Internet security are all explosive subjects. There is a sharp difference between publishing a primer about C++ and publishing a hacking guide. A book such as this one harbors certain dangers, including

• The possibility that readers will use the information maliciously
• The possibility of angering the often-secretive Internet-security community
• 
  
  
  The possibility of angering vendors that have yet to close security holes within their software
