Which best describes an insider threat? Someone who uses ______ access, _________, to harm national security through unauthorized disclosure, data modification, espionage, terrorism, or kinetic action?

An insider threat is best described as someone who uses legitimate access and privileged information to harm national security through unauthorized disclosure, data modification, espionage, terrorism, or kinetic action.

The term "insider threat" refers to a risk that originates from within an organization. Individuals who are trusted with access to sensitive systems or information, such as employees or contractors, can potentially misuse their privileges. Such threats can be intentional or unintentional and pose significant risks to national security, company integrity, and public safety. By exploiting their legitimate access, insiders can carry out actions that lead to unauthorized data exposure, manipulation of critical information, or, in severe cases, direct threats to security itself. Awareness and mitigation strategies are essential in organizations to counteract these potential risks.
