The authors, therefore, are well aware that data security becomes more complex with each passing week. This is, after all, the second edition of what was originally published under the title "Web Security and Commerce," and, while it is still recognizable as such, the work is essentially completely re- written. The authors note, in the Preface, that the book cannot hope to cover all aspects of Web security, and therefore they concentrate on those topics that are absolutely central to the concept, and/or not widely available elsewhere. Works on related issues are suggested both at the beginning and end of the book. A greatly expanded part one introduces the topic, and the various factors involved in Web security. Chapter one is a very brief overview of Web security considerations and requirements, with some material on general security concepts and risk analysis. The underlying architecture of the Web is examined in chapter two, although this is basically limited to Internet structures. (While the material is quite informative, perhaps some examples of HTTP [HyperText Transfer Protocol] would add value.) Cryptography is explained reasonably well in chapter three: there is no in-depth discussion of cryptographic algorithms, but these details can be readily found in other works. Chapter four deals with cryptographic uses, and also with legal restrictions. The concepts and limitations of SSL (Secure Sockets Layer) and TLS (Transport Layer Security) are given in chapter five, although the operational details are not covered. Chapter six starts out with a general discussion of identification and authentication,but then gets bogged down in the details of using PGP (Pretty Good Privacy). The coverage of digital certificates, in chapter seven, is likewise constricted by a dependence upon system technicalities. Part two concerns the user. Chapter two looks at the various possible problems with browsers, not all of which are related to Web page programming. Chapter eight looks analytically at the possible invasions of privacy that can occur on the Web. Some non-technical techniques of protecting your privacy, such as good password choice, are described in chapter nine, with various technical means listed in chapter ten. Chapter eleven reviews backups and some physical protection systems. ActiveX and the limitations of authentication certificates, as well as plugins and Visual Basic, are thoroughly explored in chapter twelve. Java security is only marginally understood by many "experts," and not at all by users, so the coverage in chapter thirteen is careful to point out the difference between safety, security, and the kind of security risks that can occur even if the sandbox *is* secure. Part three details technical aspects of securing Web servers. Chapter fourteen looks at physical security and disaster recovery measures. Traditional host security weaknesses are reviewed in chapter fifteen. Rules for secure CGI (Common Gateway Interface) and API (Application Programmer Interface) programming are promulgated in chapter sixteen, along with tips for various languages. More details on the server- side use of SSL is given in chapter seventeen. Chapter eighteen looks at specific strengthening measures for Web servers. You legal options for prosecuting a computer crime is reviewed in chapter nineteen. Commercial and societal concerns in regard to content are major areas in Web security, so part six reviews a number of topics related to commerce, as well as other social factors. Chapter twenty discusses a number of technical access control technologies, by system. Obtaining a client-side certificate is described in chapter twenty one. Microsoft's Authenticode system is reviewed yet again in chapter twenty two. Censorship and site blocking are carefully examined in chapter twenty three. Privacy policies, systems, and legislation are reviewed in chapter twenty four. Chapter twenty five looks at current non-cash payment systems, and the various existing, and proposed, digital payment systems for online commerce. Having already studied criminal problems earlier, the book now turns to civil and intellectual property issues, such as copyright, in chapter twenty six. Although it has almost nothing to do with Web security as such, I very much enjoyed Appendix A, Garfinkel's recounting of the lessons learned in setting up a small ISP (Internet Service Provider). (I suppose that this could be considered valid coverage of Web commerce.) The other appendices are more directly related to the topic, including the SSL protocol, the PICS (Platform for Internet Content Selection) specification, and references. Although the material has been valuably expanded and updated, some of the new content is less worthwhile. The extensive space given to specific products will probably date quickly, although the surrounding conceptual text will continue to provide helpful guidance. Certainly for anyone dealing with Web servers or running ISPs, this is a reference to consider seriously. copyright Robert M. Slade, 1998, 2002 BKWBSPCM.RVW 20021106
