Which of the following examples best represents a logical or technical control?

Security tokens are hardware or software devices that generate or store authentication credentials, making them a logical/technical control because they operate through electronic and cryptographic mechanisms rather than physical barriers or policy documents. They directly enforce access control at the system level by requiring possession of a valid token before granting entry to a resource.

Heating and air conditioning are physical/environmental controls that protect infrastructure from temperature extremes, not logical access mechanisms.

Smoke and fire alarms are physical/environmental controls designed to detect and respond to physical hazards, not to enforce information security policies.

A corporate security policy is an administrative or managerial control because it governs behavior through documented rules rather than technical enforcement.
