Which elements contribute to reducing insider threats in storage facilities?

• A. Increased outside surveillance without internal controls.
• B. Reducing training to minimal.
• C. Isolating operations from audits.
• D. Strong access controls, role-based duties, audits, ongoing training, and a culture of safety and security.

Answer: (D)

Insider threats are best prevented with a layered approach that limits what any one person can do, keeps activities visible, and reinforces safe behavior through training and culture. Strong access controls restrict who can handle sensitive materials and what operations they can perform, using principles like least privilege and need-to-know. Role-based duties ensure tasks are divided so no single person has end-to-end control, reducing opportunities for misuse. Regular audits provide ongoing oversight and the ability to detect anomalies, while ongoing training keeps everyone aware of procedures, security expectations, and the consequences of violations. A culture of safety and security makes security everyone’s responsibility, encouraging vigilance and timely reporting. The other options fall short because they either rely on external monitoring without internal safeguards, reduce personnel training (which erodes awareness and compliance), or remove accountability by isolating operations from audits. None of those create the same robust, multi-layered protection that integrates access, duties, monitoring, training, and culture.
