Answer :
Final answer:
In SCIF construction, walls indeed have to extend from the true floor to the true ceiling to prevent data leakage, according to specifications by entities like the DoD and the ICD.
Explanation:
The question pertains to the construction and security requirements of a Sensitive Compartmented Information Facility (SCIF), specifically whether the walls must extend from the true floor to the true ceiling. SCIFs are designed to prevent the leakage of sensitive information, and as such, their construction adheres to stringent security specifications. Yes, in the context of SCIF construction, walls must indeed extend from the true floor to the true ceiling. This design requirement is pivotal to prevent sound transmission and secure communication lines from being compromised. The integrity of a SCIF's walls, ceiling, and floor ensures a fully enclosed, secure environment that mitigates the risk of eavesdropping or electronic surveillance. The standards for SCIF construction are detailed in specifications provided by entities such as the Department of Defense (DoD) and the Intelligence Community Directive (ICD) which outline numerous requirements to ensure the security of sensitive compartmented information.
