Web Security eschews lengthy discussions of security theory in favor of a practical step-by-step approach. Each section is built around a "checklist" of items that readers can use to evaluate the security of their existing Web site and take action to improve it. In addition to protecting against intruders, readers will learn how to protect a Web site from other hostile Web sites. Readers will learn which resources require protection, and how they may currently be at risk. Stein explains basic strategies for protecting an existing Web site with as little cost and disruption as possible. Also covered are the risks and security solutions associated with implementing Internet services on a Web site - including http, conferencing, email, ftp, and news gateways.
