Determining Culpability in Investigations of Malicious E-mail Dissemination within the Organisation

Abstract

Investigating cases of e-mail misuse within an organization (e.g. sexist / racist content, offensive material, etc.) to determine culpability can be a complex process. Such investigations are less likely to result in a formal prosecution, but are more likely to end in disciplinary action. In a criminal investigation, the evidence is collected, analyzed and then presented to the court. In an internal corporate forensics investigation, management must not only assess evidence to determine culpability, but must also determine appropriate levels of corporate discipline to be applied. These range from informal verbal warnings through formal verbal and written warnings, to suspension or termination of employment. Such a process may often be conducted by management who have no experience of the investigatory process. The social network analysis approach presented in this paper can be used not only to analyze and appreciate what can be a complex sequence of events involved in e-mail misuse, but also to determine levels of culpability.
