Final answer:
A deadbolt door lock is an example of physical security control, which is a tangible form of protection to restrict access to assets.
Correct option is a) Physical
Step-by-step explanation:
A deadbolt door lock exemplifies a physical security control, constituting a tangible and robust measure to safeguard organizational assets. In the realm of security controls, which encompass diverse forms like physical, technical, administrative, and biometric measures, the deadbolt stands out as a physical barrier. Its purpose is to physically restrict or control access to assets, adding a layer of defense against unauthorized entry. Unlike virtual or electronic security measures, the deadbolt requires direct, hands-on interaction to enable or disable, underscoring its classification as a physical control.
This tangible manifestation of security not only fortifies the protection of assets but also symbolizes the importance of a multi-faceted security strategy that addresses various aspects of safeguarding organizational interests, including the physical realm where assets physically reside.
