Why Did We Write This Book? The Maximum Security series, which debuted in 1997, has thus far enjoyed relative success. I use the term "relative success," because security title sales have historically trickled, rather than gushed. For altering this and fostering a new market, the editors at Sams deserve kudos. Their insights have proven providential: Today, Maximum Security titles sell in five countries, five languages, and on four continents. Furthermore, the Maximum Security series has inspired many fine similar books from seasoned security professionals here and abroad. The success of the Maximum Security series is no mystery. Security has never before been so sensitive an issue, nor an issue so vital to business. Many firms have now evolved well beyond mere Web presences and incorporate sophisticated e-commerce functionality into their systems. These developments have increased the demand for books that help administrators shield their enterprises from crackers, and Maximum Security titles have—in varying degrees—satisfied that need.
