Which guideline deals specifically with criminal behavior that may affect security clearance?

The guideline that deals specifically with criminal behavior affecting security clearance is Guideline J. This guideline is focused on the potential security risks associated with an individual's criminal conduct. It encompasses various aspects of criminal behavior, including arrests and convictions, and evaluates how these factors may indicate a person's reliability, trustworthiness, and ability to protect classified information.

By examining an individual's criminal history, Guideline J aims to determine if past behaviors suggest a likelihood of future misconduct that could jeopardize national security. An important element of this guideline is the consideration of the severity and frequency of offenses, whether they demonstrate poor judgment, and if the individual has taken steps towards rehabilitation or change.

In the context of personnel security, criminal behavior is a critical area of concern because it can indicate underlying issues such as dishonesty, irresponsibility, or an inability to follow the law, all of which could pose risks in roles requiring access to sensitive information.
