NWA-PCUG 04/1999 NewsLetter Article 18861 N. Hwy 112, Springdale, AR 72762-9303 Stopping Spam: More Important Than You Might Think A Ken's Korner Book Review (Author's Note: I feel that this book and its subject are of vital interest to the entire computer community. The book's content deserves the widest possible circulation, no matter whether your platform of choice is a Mac, PC or Unix workstation. I urge you to print this review in your newsletters, post it on your web sites and relay it to your fellow computer users, not because the review itself is important but because it calls attention to an important message. Ken Fermoyle) Most of us know by now that Spam isn't just a Hormel canned meat product. Today, "spam" also means any kind of unrequested, unwanted email or newsgroup article sent in bulk over the Internet. Some people merely regard it as a nuisance. Unfortunately, Internet spam is much more than that. Spam is not something we can eliminate simply by clicking on "delete." It poses a serious problem for the cyberspace community, one we should all recognize and work to combat. The best weapon I've found so far is a new book, "Stopping Spam," from O'Reilly & Associates (www.oreilly.com). Authors Alan Schwartz and Simson Garfinkel have done an excellent job of explaining how and why spam is a major headache. More important, they describe practical ways in which individuals and organizations can use to combat this insidious menace. "Spam messages waste the Internet's two most precious resources: the bandwidth of long-distance communication links and the time of network administrators who keep the Internet working from day to day. Spam also wastes the time of countless computer users around the planet." They point out further that spammers increasingly use fraud and computer abuse to deliver their messages. They also present disturbing figures on the amount of spam jamming the Net today, and warn that the volume is increasing. The reason? Spam is probably the lowest-cost form of advertising available-to the spammer, that is. Unfortunately, it costs everyone else far more than most of us realize. One especially interesting chapter explains how messages are sent across the Internet, possibly the best and most detailed explanation of the process I've read to date. It also covers the methods spammers use to "harvest" email addresses and exploit the system in other ways. The most valuable sections of the book, however, are the strategies Schwartz and Garfunkel offer to help stop the flow of spam. Some of their solutions are technical; some are political. They tell how to use filtering and active responses to foil spammers, plus how to track down and respond to spam sources. Tools and information on web sites, programs and documents mentioned in the book are referenced in an 8-page appendix. All in all, this is a valuable book on an important subject. Well written, it includes technical material explained in such a way that you don't need a degree in computer science to get the message, but neither is it "Spam for Dummies." It will repay the thoughtful reader big dividends in useful information. I recommend it for anyone who wants to learn more about spam and Internet messaging in general. Users Groups should consider adding it to their libraries.
