Insider Threat Study [Moore07]
- Analyzed 150 insider cyber crimes, focusing on detailed modeling of 30 cases.
- Seven key observations for insider IT sabotage include:
- Personal predisposition
- Unmet expectations
- Stressful events
- Behavioral precursors
- Technical precursors
- Unknown access paths
- Lack of controls
Personal Predisposition
- Insiders often had existing characteristics tied to a tendency for malicious behavior.
Unmet Expectations
- Disgruntlement stemming from unmet work-related expectations often led to IT sabotage.
Stressful Events
- High-stress situations increased the likelihood of insider IT sabotage occurring.
Behavioral Precursors
- Actions or conditions observable before malicious insider activities serve as indicators of potential threats.
Technical Precursors
- Organizations frequently overlook individual actions or conditions involving technology related to insider threats, such as password sharing or persistent system access.
Unknown Access Paths
- Insiders may exploit hidden access paths to unauthorized systems, like creating backdoors.
Lack of Controls
- Insufficient physical and electronic controls can enable IT sabotage activities.
Business Dynamics Notations
- Visual representation of the seven observations: solid arrows indicate positive influence, while dashed arrows indicate negative influence.
- Balancing loops drive organizational variables toward stability, while reinforcing loops lead to consistent upward or downward trends.
How to Address Insider Threats
- Mitigation strategies include setting clear expectations, proactive handling of disgruntlement, targeted monitoring, closing unknown access paths, and implementing measures upon employee demotion or termination.
