A city deploys IoT parking sensors that are embedded in the pavement. The sensors store configuration data and are powered by a battery. The city is concerned about vandals digging up the sensors and attempting to extract configuration data. Which feature is most important for the sensors to have?

A bright LED indicator that flashes when the sensor is active

A tamper-resistant housing that erases cryptographic keys if the enclosure is breached

A long-range wireless antenna for better connectivity

A replaceable battery that extends the sensor's operational life

Which measure is most effective for preventing unauthorized data exfiltration through a USB port on an IoT device?

Placing a sticker over the USB port

Disabling unused USB ports in firmware or via configuration

Increasing the USB port's power output

A research lab stores sensitive experimental data on portable USB drives used with IoT sensors. A drive was lost during transport. The lab's policy requires that the data remain confidential even if the drive is lost or stolen. Which measure directly satisfies this policy?

Label the drive with 'Confidential' and instruct staff to keep it in a locked drawer when not in use

Store the data on a cloud service instead of a USB drive

Encrypt the entire USB drive with a strong passphrase and enforce a policy that the passphrase is not stored with the drive

Use a ruggedized USB drive that is resistant to physical damage

Which measure is most effective for limiting physical access to critical IoT components in a facility?

Using a standard office space without any locks

Publishing the location of the components on a public map

Placing components in a locked server room with access control

Labeling the components as 'critical infrastructure'

A water treatment facility uses USB ports on its pump controllers for firmware updates. After an audit revealed that a cleaning contractor plugged a personal USB drive into one controller, the facility manager wants to prevent unauthorized device connections while still allowing authorized maintenance. What should you implement?

Enable USB port access control that only permits connections from vendor-authorized USB devices with valid certificates

Install a USB data blocker on each controller and rely on the existing antivirus software to detect malware

Apply epoxy to the USB ports and require physical removal of the controller for any firmware update

Disable the USB ports in the controller firmware and require a hardware programmer for all updates
