A9) Where can I get more information on viruses, etc.? There are four excellent books on computer viruses available that should cover most of the introductory and technical questions you might have: * "Computers Under Attack: Intruders, Worms and Viruses," edited by Peter J. Denning, ACM Press/Addison-Wesley, 1990. This is a book of collected readings that discuss computer viruses, computer worms, break-ins, legal and social aspects, and many other items related to computer security and malicious software. A very solid, readable collection that doesn't require a highly-technical background. Price: $20.50. * "Rogue Programs: Viruses, Worms and Trojan Horses," edited by Lance J. Hoffman, Van Nostrand Reinhold, 1990. This is a book of collected readings describing in detail how viruses work, where they come from, what they do, etc. It also has material on worms, trojan horse programs, and other malicious software programs. This book focuses more on mechanism and relatively less on social aspects than does the Denning book; however, there is an excellent piece by Anne Branscomb that covers the legal aspects. Price: $32.95. * "A Pathology of Computer Viruses," by David Ferbrache, Springer-Verlag, 1992. This is a recent, in-depth book on the history, operation, and effects of computer viruses. It is one of the most complete books on the subject, with an extensive history section, a section on Macintosh viruses, network worms, and Unix viruses (if they were to exist). * "A Short Course on Computer Viruses", by Dr. Fred B. Cohen, ASP Press, 1990. This book is by a well-known pioneer in virus research, who has also written dozens of technical papers on the subject. The book can be obtained by writing to ASP Press, P.O. Box 81270, Pittsburgh, PA 15217. Price: $24.00. A somewhat dated, but still useful, high-level description of viruses, suitable for a complete novice without extensive computer background is in "Computer Viruses: Dealing with Electronic Vandalism and Programmed Threats," by Eugene H. Spafford, Kathleen A. Heaphy, and David J. Ferbrache, ADAPSO (Arlington VA), 1989. ADAPSO is a computer industry service organization and not a publisher, so the book cannot be found in bookstores; copies can be obtained directly from ADAPSO @ +1 703-522-5055). There is a discount for ADAPSO members, educators, and law enforcement personnel. Many people have indicated they find this a very understandable reference; portions of it have been reprinted many other places, including Denning & Hoffman's books (above). It is also worth consulting various publications such as _Computers & Security_ (which, while not restricted to viruses, contains many of Cohen's papers) and the _Virus Bulletin_ (published in the UK; its technical articles are considered good, although there has been much criticism in VIRUS-L of some of its product evaluations). .
