Most computer security books assume that readers are full-time security specialists, or at least system administrators with a strong interest in keeping their networks safe. These books tend to require prior knowledge and are oriented toward corporation-size systems. PC Confidential, thankfully, takes an alternate approach. It explains how you, with your average Windows-based PC and modem, can protect yourself from all sorts of computer-centric unpleasantness. Whether you"re worried about viruses, file thieves, or Internet snoops, this book has some good advice. It does make some controversial points, among them a recommendation that you turn off your browser"s cookie-storage feature completely (although some sites won"t work if you do that). You might want to think twice before disabling cookies altogether. Generally, however, the advice is worth heeding. As is always the case with security books, the recommendations sometimes seem too common-sensical (change your password frequently, don"t give your telephone number to people you don"t know well, and so on); but, even so, there"s enough clever material here to make the book a decent value. Author Michael A. Banks works as a computer-security consultant to police agencies, and his stories of electronic shenanigans make great reading. Future editions ought to include information about personal firewalls, such as BlackIce Defender (essential on home networks that are hooked to cable modems and other connections that are always on) and Windows utilities, such as TweakUI and its Paranoia features. --David Wall Topics covered: Computer security for the Windows-based PC, operating as a stand-alone unit in a home or small office and contacting the Internet via a dialup connection. How to use antivirus software, encryption tools, authentication techniques, and some sneaky ways to increase security through file concealment.
