A wastewater treatment facility has a perimeter fence and a single gate. The security team wants to detect an intruder climbing over the fence at night. Which monitoring and surveillance control is most effective for this specific threat?

Install a motion-activated light at the gate only

Install a fence-mounted vibration sensor that triggers an alarm when the fence is disturbed

Increase the height of the fence by one meter

Add a sign that warns of prosecution for trespassing

A remote pumping station is located in a desert area with extreme heat. The station houses a PLC and a small network switch. The station has no air conditioning. Which environmental control is most critical to prevent equipment failure?

Paint the station exterior a dark color to absorb heat

Install a cooling system such as an air conditioner or heat exchanger rated for the ambient temperature range

Add a backup battery to the PLC

Install a motion sensor to detect intruders

Which of the following is a surveillance control commonly used for physical security in ICS environments?

An antivirus software on engineering workstations

Closed-circuit television (CCTV) cameras

A network-based intrusion prevention system (IPS)

A virtual private network (VPN) for remote access

A security guard at a power plant discovers that a server cabinet in the control room has been opened and a USB drive is plugged into a critical HMI. The guard is not trained in cyber incident response. What should the guard do?

Remove the USB drive and place it in a secure envelope for evidence

Disconnect the HMI from the network to contain the incident

Do not touch the USB drive, secure the area, and immediately notify the cyber incident response team

Reboot the HMI to clear any potential malware
