Final answer:
The statement that SIPRNET removable hard drives may be stored in a fireproof, keyed file cabinet is false; they require storage in a GSA approved security container.
Step-by-step explanation:
The statement that SIPRNET removable hard drives may be stored in a fireproof, keyed file cabinet is false. SIPRNET, or Secret Internet Protocol Router Network, is a system of interconnected computer networks used by the U.S. Department of Defense and the U.S. Department of State to transmit classified information. The security protocols for handling and storing SIPRNET hardware are much more stringent than simply using a fireproof, keyed file cabinet. The storage of such sensitive materials generally requires adherence to specific governmental physical security standards, such as using a General Services Administration (GSA) approved security container and following established security procedures. These standards are designed to prevent unauthorized access to classified information and ensure the security of national security assets.
