What is the primary function of a tamper-resistant device?

To improve the device's processing speed

To reduce the device's power consumption

To increase the device's wireless signal strength

To detect or deter physical tampering with the device

An IoT device stores its firmware update files on a microSD card. Which practice best protects the card from unauthorized access while the device is in the field?

Disabling the device's LED indicators

Leaving the card accessible for easy replacement

Sealing the card slot with tamper-evident adhesive

A utility company is deploying smart meters in an area with a history of meter tampering to reduce reported consumption. The meters will store consumption data locally. Which device feature is most important to select to deter and detect physical manipulation of the meter's internal components?

A high-capacity battery that keeps the meter running during a power outage

A tamper-evident enclosure with a switch that triggers an alert when the cover is opened

A plastic housing that is easy to open for maintenance

A large LCD display that shows the current consumption reading

A remote oil pipeline monitoring station has an IoT gateway that is accessed via SSH for maintenance. The gateway is in a locked cabinet, but the cabinet key is held by multiple contractors. An audit found that a contractor's SSH session was left open and used to change the gateway's configuration. What is the most effective way to prevent this specific issue?

Use a stronger SSH password that is changed monthly

Change the cabinet lock and issue keys only to full-time employees

Disable SSH and require on-site console access for all maintenance

Configure SSH idle timeout and session termination after a short period of inactivity

What is the purpose of monitoring shell access on an IoT device?

To detect unauthorized access or suspicious command execution

To reduce the device's power consumption

To simplify the device's user interface

To increase the device's processing speed
