A vibration sensor can detect attacks against which of the following?

A vibration sensor is designed to detect physical disturbances such as tapping, drilling, or any other vibrations that may occur when an unauthorized attempt to access a secured area or object is made. This technology can be applied to various security contexts, making it versatile when it comes to protecting valuable assets.

In the context of ATMs, these sensors can detect vibrations caused by tampering attempts, such as drilling into the machine or trying to pry it open. Similarly, for vaults, vibration sensors are effective at picking up on attempts to break through the heavy and reinforced materials typically used in vault construction. Lastly, metal cabinets that might contain sensitive information or valuables can also be monitored for similar physical intrusion attempts.

Since vibration sensors can be effectively employed to monitor all these scenarios, the option indicating that they can detect attacks against ATMs, vaults, and metal cabinets collectively provides the most comprehensive understanding of their capability. This versatility in application justifies choosing a response that encompasses all listed scenarios.
