How does physical security relate to the Protect function?

• A.Only data centers need physical security, and it presupposes that roles and responsibilities belong only to Protect and that the Protect function excludes physical and environmental safeguards
• B.Physical security only protects against natural disasters, because facility power and HVAC resilience are outside the Framework's PROTECT outcomes; beyond that, underspending against the action plan triggers removal from NIST's adopter listing
• C.Physical security controls (locks, cameras, access badges, environmental controls) protect hardware, facilities, and physical assets from unauthorized access, theft, and environmental damage
• D.Physical security is not part of the NIST CSF
