A. B. C. D. E. F.D.
An iris scanner is a type of biometric authentication system that uses the unique patterns of the iris (the colored part of the eye surrounding the pupil) to identify individuals.
Out of the security controls listed in the question, an iris scanner provides a Physical control. Physical controls are security measures implemented to protect the physical assets of an organization, such as buildings, equipment, and people.
In the case of an iris scanner, it is a physical control because it is a device that is physically installed at a specific location (e.g., a doorway or entrance) to control access to a physical space or resource. Only authorized individuals with registered iris patterns will be allowed to enter the secured area, while unauthorized individuals will be denied entry.
Therefore, the correct answer is D. Physical. Logical controls refer to security measures implemented through software or logical means, administrative controls refer to security measures implemented through policies and procedures, corrective controls refer to security measures that address an incident after it has occurred, detective controls refer to security measures that detect and alert to security incidents or breaches, and deterrent controls refer to security measures that discourage or prevent potential attackers from attempting to breach security measures.
