Detection of Employees’ Carelessness Leading to Cause Insider Threats through Analyzing Email RDF Data

Abstract

In recent years, many businesses have been put in a great deal of effort to develop ways to fight
against threats posed by insiders of them. Insider threats can be perpetrated for the purpose of doing
harm to a business, but in some cases, they are done by mistake. And those mistakes also can be
made by carelessness of employees who do not have any malicious purpose to harm their company.
In this paper, we suggest the need to watch those employees’ actions that might be a clue about their
carelessness. Email messages are one of the useful resources to watch because it is the media employees
use on a daily basis at work and each message can reflect the writer’s feeling or what they
are doing at work by words. In this paper, with an experiment, we suggest closely waching some of
email behaviors can tell us about clues to which employee is carelessness now and has the potential
danger to make mistakes that might lead to a serious damage to the business.
