Question 43

Explanation

The correct answer: Physical access controls are typically the first to be implemented for a wiring closet. This is due to the fact that a wiring closet usually contains sensitive equipment such as servers, routers, and other networking devices that are critical for the operations of an organization. Physical access controls such as door locks, security cards, biometric access control systems, etc., are employed to ensure that only authorized personnel can access these spaces. This helps to prevent unauthorized access, theft, damage, or tampering, which can lead to severe consequences including data loss, downtime, or even breaches of sensitive information. The incorrect answers: Fire suppression system: Although a fire suppression system is essential in a wiring closet to prevent damage from unexpected fire incidents, it is typically not the first security control to be implemented. Before considering fire threats, the immediate concern is usually about unauthorized access, which can cause more frequent and diverse types of threats such as theft or tampering. Physical access control is generally prioritized. Video surveillance is an important part of security but usually it is not the first line of defense for a wiring closet. It serves as a deterrent and provides a means to identify individuals in the event of security incidents. Video surveillance does not prevent unauthorized access to the wiring closet. An unauthorized person could potentially still access the equipment if there are no physical access controls in place, despite the presence of video surveillance. Access control lists for network devices: Access Control Lists (ACLs) are an important part of network security and help to control which users or systems can access network devices. This is a form of logical or digital security rather than physical security. If an unauthorized person can physically access the networking equipment, they can bypass many of the logical security controls like ACLs. Physical access controls are typically the first line of defense, followed by logical controls like ACLs.
