• B. To provide physical security for COMSEC
• C. To handle materials in transit
• D. To account for all materials

Answer: (B)

The essential function of the "Safeguard" part of the RADISH acronym is to provide physical security for COMSEC materials. This involves implementing measures to protect classified information from unauthorized access, theft, or tampering. By ensuring that physical security protocols are in place, organizations can secure COMSEC materials throughout their lifecycle, from storage to transportation to disposal. This aspect of security is vital to maintain the confidentiality, integrity, and availability of sensitive communications, preventing adversaries from gaining access to critical information that could compromise national security or operational effectiveness.
