What is a Security Clearance?

A Security Clearance is fundamentally defined as a determination that a person is eligible for access to classified information. This involves a thorough background investigation and evaluation process that assesses an individual's trustworthiness, reliability, and loyalty to the United States, ensuring they can be granted access to sensitive national security information.

Possessing a Security Clearance means the individual has met specific standards set by the government, allowing them to work with information that requires protection from unauthorized disclosure. This level of scrutiny ensures that only individuals deemed suitable based on criteria like criminal history, financial responsibility, and personal conduct are given access to classified materials, thereby safeguarding national security interests.

While other choices pertain to security and access, they do not capture the full scope and critical importance of what a Security Clearance represents in relation to classified information.
