Which is NOT an early indicator of a potential insider threat?

A reasonable disagreement with a U.S. Government policy does not serve as an early indicator of a potential insider threat because it reflects a normal aspect of human behavior—differing opinions and beliefs about policies and governance. Such disagreements can arise from personal values, experiences, or political views and do not inherently signify malicious intent or the potential for harm.

In contrast, the other options represent concerning behaviors that could indicate an insider threat. Abnormal mood swings, depression, and suicidal remarks suggest significant emotional distress that might lead to harmful actions. The presence of unauthorized weapons raises immediate safety concerns, as it can signal a readiness or intent to cause harm. Aggression or threats toward co-workers can indicate underlying hostility or potential for violent actions, which is a clear warning sign of a possible insider threat.

Recognizing the distinction between a difference of opinion and behaviors that indicate a risk of violence is critical for maintaining a safe environment and responding appropriately to potential insider threats.
