内容説明

62820-6 The complete Webmaster's guide to Website security. Whether you have a Website, an intranet, or both, Protecting Your Website with Firewalls is your end-to-end resource for maximizing security. This highly readable, hands-on book covers all the security choices associated with virtually every Internet resource, including: *WWW/HTTP. *Conferencing. *E-mail. *FTP. *News gateways/NNTP. *Telnet. Learn how firewalls, packet filtering, and proxy servers work-and how you can use them to protect your site with minimum cost, disruption, and complexity. Explore the leading HTTP security protocols, Secure-HTTP, and Secure Sockets Layer (SSL), as well as today's advanced authentication and encryption solutions. Then, walk step-by-step through planning, implementing, and maintaining your firewall and related security technologies. Protecting Your Website with Firewalls includes detailed checklists, step-by-step instructions, and case studies to help you identify common security gaps at your site-and systematically close them. Learn how to decide which resources are worth protecting-and which may not be worth the trouble.Finally, if you do have a break-in, the book shows you what to do next-both to improve security and to pursue the intruder. The accompanying CD-ROM includes the comprehensive TIS security toolkit for Windows NT servers. Protecting Your Website with Firewalls also contains comprehensive, up-to-date resource listings for: *Tools that can identify weaknesses and improve authentication and passwords. *Firewall products, resellers, and consultants. *Software patches to enhance security. Your Internet connection places your most critical business secrets at risk. With this conversational, thorough guide, you can dramatically reduce those risks now -and for years to come.
