Unauthorized computer access by employees is the most common hacking behavior in every company. Hence, it is necessary to first understand why an employee engages to commit it and then find effective methods of prevention to reduce the crime rate. Many studies on computer hacking has discussed the reasons for the behavior, for example: neutralization theory, differential association theory and containment theory. However, those theories and perspectives were adopted independently in past research. In this study, we combine those perspectives and create an integrated model to explain the employee¡¦s intention to commit unauthorized computer access. Data collected from 351employees in Taiwan confirmed our hypotheses and were tested against the research model. The results support the theoretical model in explaining how neutralization theory and containment theory may affect an employee¡¦s intention to commit unauthorized computer access. Finally, we found that neutralization is the most important factor to take into account when organizations develop and implement security policies or education which can decrease employees¡¦ intentions to commit unauthorized computer access.
