Computer Crime

A computer crime is generally defined as one that involves the use of computers and software for illegal purposes. This doesn\'t mean that all the crimes are new types of crime. On the contrary, many of these crimes, such as embezzlement of funds, the alteration of records, theft, vandalism, sabotage, and terrorism, can be committed without a computer. But with a computer, these offenses can be carried out more quickly and with less chance that the person responsible for the crime will be discovered.

Computer crimes are on the rise and have been for the last twelve years. Just how much these computer crimes cost the American public is in dispute, but estimates range from $3 billion to $5 billion annually. Even the FBI, which attempts to keep track of the growth or decline of all kinds of crimes, is unable to say precisely how large a loss is involved; however, it estimates that the average take from a company hit by computer crime is $600,000. A number of reasons are given for the increase in computer crime: A more computers in use and, thus, more people who are familiar with basic computer operation; B more computers tied together in satellite and other data—transmission networks; and C the easy access of microcomputers to huge mainframe data bases.
