Title: Insider Threat Awareness

Practice:
Provide security awareness training on recognizing and reporting potential indicators of insider threat.

Further Discussion:
An insider threat is the threat that an insider will use their authorized access, wittingly or unwittingly, to do harm. Insider threat security awareness training focuses on recognizing employee behaviors and characteristics that might be indicators of an insider threat and the guidelines and procedures to handle and report it. Training for managers will provide guidance on observing team members to identify all potential threat indicators, while training for general employees will provide guidance for focusing on a smaller number of indicators. Employee behaviors will vary depending on roles, team membership, and associated information needs. The person responsible for specifying insider threat indicators must be cognizant of these factors. Because of this, organizations may choose to tailor the training for specific roles. This requirement does not require separate training regarding insider threat. Organizations may choose to integrate these topics into their standard security awareness training programs.

Example
You are responsible for training all employees on the awareness of high-risk behaviors that can indicate a potential insider threat [b]. You educate yourself on the latest research on insider threat indicators by reviewing a number of law enforcement bulletins [a]. You then add the following example to the training package: A baseline of normal behavior for work schedules has been created. One employee’s normal work schedule is 8:00 AM–5:00 PM, but another employee noticed that the employee has been working until 9:00 PM every day even though no projects requiring additional hours have been assigned [b]. The observing employee reports the abnormal work schedule using the established reporting guidelines.

Potential Assessment Considerations
• Do training materials include potential indicators associated with insider threats (e.g., repeated security violations, unusual work hours, unexpected significant transfers of data, suspicious contacts, concerning behaviors outside the workplace) [a,b]?
• Do training materials include methods of reporting potential indicators of insider threats to management or responsible security personnel [b]?
