Many of the high-profile attacks on prominent Web sites of the last couple years are a direct result of poor Web site or Web application security.
With more than 65 percent of Web sites using the Apache Web server and the Apache-based open source Web development environment and with the risk of sabotage greater than ever Apache administrators and developers need to know how to build and maintain secure Web servers and Web applications.
Yet most of the currently available Apache books lack detailed information on important Web administration topics like security. Maximum Apache Security details the complex security weaknesses and risks of Apache, and provides hands-on solutions for keeping a Web site secure and buttressed against intruders. It includes up-to-date coverage of both Apache 2.0 as well as Apache 1.3.
(NOTE: Each chapter concludes with a Summary.)
