Internet of Things (IoT)

Correct Answer: Segment the network and implement bandwidth management techniques

Segmenting the network and implementing bandwidth management techniques is the most practical approach to manage and maintain the IoT network more efficiently in the hospital. Network segmentation helps isolate different types of devices and traffic, ensuring that critical devices receive priority and sufficient bandwidth. Bandwidth management techniques, such as Quality of Service (QoS), can prioritize traffic based on importance, ensuring that essential devices and applications have the necessary network resources. Disconnecting non-essential devices may disrupt hospital operations and is not a viable long-term solution. Manually adjusting network settings for each device is time-consuming and prone to errors, especially with a large number of IoT devices. Replacing IoT devices with non-networked ones would negate the benefits of connected devices and hinder the hospital's ability to monitor and manage patient care effectively.

Correct Answer: Decrease the distance between the IoT device and the wireless access point.

Decreasing the distance between the IoT device and the wireless access point is the best solution. In a wireless network, the signal strength and quality degrade as the distance between devices increases. By placing the IoT device closer to the access point, the connection will be more stable and reliable. Switching to a wired connection is not always feasible for IoT devices designed for wireless use. Replacing the access point may not be necessary if the issue is related to distance. Purchasing a new IoT device does not address the root cause of the connectivity problem.

Correct Answer: Change the passwords, update firmware, and ensure proper network security

The best answer is to change the passwords, update firmware, and ensure proper network security. Changing passwords will prevent the hacker from continuing to access the devices using compromised credentials. Updating firmware will patch any known vulnerabilities that may have been exploited. Ensuring proper network security, such as using a firewall and securing the Wi-Fi network, will help prevent future attacks. Replacing all devices is unnecessary and costly. Completely disconnecting the devices from the internet would make them unusable for their intended purposes. Covering the devices with protective sleeves does not address the underlying security issues.
