Written for Web site administrators, developers, and end users, this book is a readable, real-world guide to securing your Web site with the latest in security technology, techniques, and tools. Lincoln D. Stein, keeper of the official World Wide Web Security FAQ, addresses your most pressing concerns and tells you exactly what you need to know to make your site more secure. He offers concise explanations of essential theory; helps you analyze and evaluate the risks and that threaten your site and the privacy of your clients; and provides concrete, step-by-step solutions, checklists of dos and don'ts, on-line and off-line resources, and hardware and software tools that guard your site against security breaches. Web Security approaches to topic from three different points of view - protecting the end user's confidentiality and the integrity of his or her machine, protecting the Web site from intrusion and sabotage and protecting both from third-party eavesdropping and tampering.
