How can you detect if a system case cover has been removed?

1. Using a power supply monitor

2. Chassis intrusion detection

3. Power brokerage

4. Network scanning tools

The correct answer is: Chassis intrusion detection

Chassis intrusion detection is a feature implemented in many computer systems that helps monitor the physical security of the case. When the cover of the system case is removed, a switch or sensor inside the chassis is triggered, notifying the system that the cover has been taken off. This detection can be done through BIOS settings or software that logs the event, often informing the user or administrator that unauthorized access has occurred. This method of security is particularly important in environments where data security and hardware integrity are critical, as it serves as a deterrent against tampering or physical security breaches. The event may also trigger alerts or logs that can aid in further investigation or notification of potential security incidences.
