Explanation

Security controls are classified along two axes: function (preventive, detective, corrective) and layer (administrative/physical/technical). Technical controls-also called logical controls-are implemented in hardware or software (e.g., encryption, access control lists, firewalls, authentication systems). Their primary function is preventive: they are designed to stop unauthorized access or data exposure before it occurs. Therefore, encryption and access control represent a Preventive/Technical pairing. (A) Administrative controls involve policies and procedures, not software. (C) Physical controls involve locks, fences, and hardware barriers. (D) Detective/Technical controls detect incidents after they occur (e.g., IDS, audit logs), which does not describe encryption or access control whose purpose is prevention.
