Who must approve "interim" personnel security clearances according to DoD regulations?

The approval of "interim" personnel security clearances in accordance with DoD regulations is the responsibility of the Cognizant Security Office. This office plays a crucial role in the personnel security process, ensuring that individuals who require access to classified information meet the necessary security standards. The Cognizant Security Office evaluates the circumstances surrounding the need for an interim clearance and assesses the available information to make an informed decision.

Interim clearances are typically granted to allow individuals to begin work on classified contracts while their full security clearance investigations are ongoing. This process includes reviewing various factors that indicate the individual's trustworthiness and reliability. The involvement of the Cognizant Security Office is vital since they have the authority and necessary insight into the security procedures and requirements outlined in the DoD's policies.

In contrast, while the other entities like the Defense Intelligence Agency, Industrial Clearance Office, and Contracting Officer play important roles in broader security or contractual processes, they do not hold the direct authority to approve interim clearances. The focus on the Cognizant Security Office reflects the specific requirements and regulations governing personnel security within the Department of Defense.
