Since the first edition of this classic reference was published, World Wide Web use has exploded and e-commerce has become a daily part of business and personal life. As Web use has grown, so have the threats to our security and privacy--from credit card fraud to routine invasions of privacy by marketers to web site defacements to attacks that shut down popular web sites. Web Security, Privacy & Commerce goes behind the headlines, examines the major security risks facing us today, and explains how we can minimize them. It describes risks for Windows and Unix, Microsoft Internet Explorer and Netscape Navigator, and a wide range of current programs and products. In vast detail, the book covers:
Web technology--The technological underpinnings of the modern Internet and the cryptographic foundations of e-commerce are discussed, along with SSL (the Secure Sockets Layer), the significance of the PKI (Public Key Infrastructure), and digital identification, including passwords, digital signatures, and biometrics.
Web server security--Administrators and service providers discover how to secure their systems and web services. Topics include CGI, PHP, SSL certificates, law enforcement issues, and more.
Web content security--Zero in on web publishing issues for content providers, including intellectual property, copyright and trademark issues, P3P and privacy policies, digital payments, client-side digital signatures, code signing, pornography filtering and PICS, and other controls on web content.
Nearly double the size of the first edition, this completely updated volume is destined to be the definitive reference on Web security risks and the techniques and technologies you can use to protect your privacy, your organization, your system, and your network.
