Physical Control

B.

Physical controls are items put into place to protect facility, personnel, and resources.

Examples of physical controls are security guards, locks, fencing, and lighting.

The following answers are incorrect answers: Monitoring of system activity is considered to be administrative control.

Identification and authentication methods are considered to be a technical control.

Logical access control mechanisms is also considered to be a technical control.

The term physical controls refers to the use of tangible measures to restrict access to systems or facilities. These controls are implemented to prevent unauthorized access, theft, or damage to hardware, software, or data. Physical controls can range from simple locks to complex biometric authentication systems.

Among the given options, fencing is the best example of a physical control. Fencing is a physical barrier that is designed to restrict access to a specific area. It can be made of a variety of materials, such as wood, metal, or plastic, and can be used to create a perimeter around a building, a data center, or a restricted area within a facility. Fencing can also be combined with other physical controls, such as security cameras, lighting, and alarms.

Monitoring of system activity, identification and authentication methods, and logical access control mechanisms are all examples of technical or administrative controls, rather than physical controls.

Monitoring of system activity refers to the process of tracking and analyzing events that occur within a system. While monitoring can be used to detect security incidents, it is not a physical control as it does not physically restrict access to a system.

Identification and authentication methods are used to verify the identity of a user before granting access to a system. While authentication methods may involve physical tokens such as smart cards or biometric scanners, the process itself is not a physical control.

Logical access control mechanisms are used to manage access to computer systems by defining and enforcing user roles and permissions. Logical access control mechanisms are not physical controls because they do not restrict access to a physical location or device.

In conclusion, fencing is the best example of a physical control among the given options.
