This paper will examine the growing problem of computer crime in this country. Several different types of computer crime, as well as preventative measures for each, will be addressed.

Experts estimate that 80 percent of computer security breaches are internal. The second major category is external computer crime, which consists of unauthorized invasions of a system by outside persons, commonly known as hackers. With over 33 million desktop machines in use today, it is estimated that literally hundreds of thousands of people have now acquired the skills necessary to penetrate most systems.

Hardware-based crimes are basically limited to electronic eavesdropping or wiretapping. Software-based crimes, on the other hand, are much more insidious and pervasive. This subcategory includes the notorious computer "virus". A virus is a tiny bit of software hidden within a larger, seemingly innocuous, program or "Trojan horse." A virus can do anything from merely delivering a surprise message (i.e. "Gotcha!") to wiping out every shred of data in a computer's memory. Virusses are so named because they are designed to self-replicate and spread throughout a network. Destructive software that wipes out memory but does not spread is called a "worm."

Many corporations now employ a variety of security measures to prevent these four types of computer crime. As mentioned ...
