Which of the fallowing security controls does an iris scanner provide?

Logical controls restrict access to computer systems, networks, or data through software-based mechanisms like passwords, encryption, or access control lists.

Administrative controls are policies, procedures, and guidelines established by an organization to manage security risks and dictate behavior.

Corrective controls are implemented after a security incident to minimize damage, restore systems, and prevent recurrence.

An iris scanner provides physical security control because it directly regulates access to a tangible location or resource, such as a server room or building, by verifying an individual's unique biometric data at the point of entry. It acts as a barrier that prevents unauthorized persons from physically accessing a protected area.

Detective controls identify and alert about security incidents *after* they have occurred, such as intrusion detection systems or security logs.

Deterrent controls discourage potential attackers from attempting to breach security, often by making the target seem less appealing or harder to compromise through visible security measures.
