Sources of Insider Threats

Employees

Employees of an organization are amongst the greatest risk in terms of access to and potential harm with an organization’s sensitive material. Organizations typically assume that they can trust their employees. They believe that their employees are primarily interested in the productivity and successfulness of the organization. Therefore they are not considered to be of any possible danger and are considered last when a leak of sensitive material has occurred.

Contractors

Info

Former Employees

Former employees who pose a threat to their former organization are typically disgruntled employees. They believe that the organization has “done them wrong” and feel that revenge is justified. They are able to gain access to sensitive material either:

• Directly: Through a back door. If an employee fears termination, he or she may prepare a backdoor access or alternative usernames and passwords in order to gain entry. They may also begin collecting proprietary data for later use.
• Indirectly: Through former associates. A former associate may create a back door access for the former employee or may provide him or her with proprietary information.

Preventions

Background Checks

Several organizations do not perform adequate background verification on their new employees. Screening new employees properly, such as reference checks or inspecting criminal records, can reduce the probability of an organization hiring individuals that may be an insider threat. Background checks should be performed for all individuals who are given access to an organization's sensitive materials even if they are not directly employed by the organizations (e.g.: Contractors).
