The article focuses on the effectiveness of computer misuse policies among university students. A study of Midwestern college students found that more than a third of business students, (undergraduate and graduate), had misused computer system resources or software in their lifetimes. Paradoxically, the study found that students who had read the computer misuse policy of the university committed more abuse. Greater familiarity with computers was also an indicator of greater levels of computer misuse; in general, undergraduate misuse was lower than graduate student misuse. The study's implications for corporate computer use policies are discussed.
