Segment the Staff WiFi Network from Environmental Systems Network

The facilities supervisor for a government agency is concerned about unauthorized access to environmental systems in the event the staff WiFi network is breached.

Which of the following would BEST address this security concern?

A.

Install a smart meter on the staff WiFi.

B.

Place the environmental systems in the same DHCP scope as the staff WiFi.

C.

Implement Zigbee on the staff WiFi access points.

D.

Segment the staff WiFi network from the environmental systems network.

D.

The best way to address the security concern of unauthorized access to environmental systems in the event of a staff WiFi network breach is to segment the staff WiFi network from the environmental systems network.

Segmentation is the process of dividing a network into smaller subnetworks or segments, each with its own security controls and access policies. By segmenting the staff WiFi network from the environmental systems network, unauthorized access to the staff WiFi network will not grant access to the environmental systems network, and vice versa.

Installing a smart meter on the staff WiFi (option A) would not address the security concern of unauthorized access to environmental systems. A smart meter is a device used to measure energy consumption and does not offer any security benefits.

Placing the environmental systems in the same DHCP scope as the staff WiFi (option B) would also not address the security concern as DHCP (Dynamic Host Configuration Protocol) is a network management protocol used to automatically assign IP addresses to devices on a network. This option does not provide any security measures for protecting the environmental systems network.

Implementing Zigbee on the staff WiFi access points (option C) is a wireless protocol used for low-power, low-data-rate IoT devices. This option also does not address the security concern of unauthorized access to environmental systems.

Therefore, segmenting the staff WiFi network from the environmental systems network (option D) is the best solution to address the security concern of unauthorized access to environmental systems in the event of a staff WiFi network breach.
