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

Security tokens are technical (logical) controls because they enforce authentication and access decisions through a hardware or software-based mechanism, such as OTP generators or smart cards. They operate at the system or application layer, distinguishing them from physical or administrative controls. This makes them a direct example of a logical or technical control.

Heating and air conditioning is an environmental or physical control, not a logical or technical one, as it protects hardware through climate management rather than through system-level enforcement.

Smoke and fire alarms are physical or environmental controls designed to detect and alert on physical threats, not to enforce access or system policies.

A corporate security policy is an administrative (managerial) control - it governs behavior through rules and procedures rather than through a technical or hardware mechanism.
