In an expeditionary environment, what does the term insider threat describe?

The term insider threat in an expeditionary environment specifically refers to individuals who have been entrusted with access to sensitive information or structures and subsequently misuse that trust to carry out harmful actions. This can include active attacks against DOD service members or efforts to compromise security, often motivated by various personal or ideological grievances.

This definition aligns well with the concept of insider threats, which emphasizes the danger posed by individuals who, due to their position, can exploit their knowledge or access to cause harm. It underscores the critical need for vigilance and robust security measures to identify and mitigate such risks, especially in sensitive operational environments.

The other options focus on different types of threats or actions that, while potentially dangerous, do not capture the specific essence of an 'insider threat' as it pertains to the focused context of someone who is trusted within the organization.
