Define "insider threat program" in the context of personnel security.

The definition of an "insider threat program" in the context of personnel security is centered around the need to protect sensitive information and assets from individuals who have legitimate access to them. The correct answer identifies this focus on detecting, deterring, and mitigating risks posed by insiders—such as employees, contractors, or other personnel—who might misuse their access either intentionally (malicious insiders) or unintentionally (negligent insiders).

This program is essential for safeguarding classified or sensitive data, as insiders can leverage their positions to cause significant harm without the same level of scrutiny that external threats might face. By implementing an insider threat program, organizations can proactively monitor behavior, establish a culture of security awareness, and foster reporting mechanisms to handle potential threats before they escalate.

The other options do not align with the purpose of an insider threat program. Managing external security risks, focusing on workplace injuries, or specializing solely in physical security measures does not address the unique challenges posed by individuals within the organization who can access confidential information. Therefore, they are not relevant in defining what an insider threat program entails.
