What is the first step in responding to a physical security incident at an ICS facility?

Restore all systems to normal operation

Contain the incident to prevent further damage or unauthorized access

Conduct a full forensic investigation

A small water utility has a SCADA system with a control room located in the same building as the administrative offices. The utility wants to improve physical security without major renovation. Which approach is most aligned with the principle of defense-in-depth?

Move the control room to a different building with no windows

Rely on the existing building alarm system that covers the entire facility

Add a lock to the control room door and install a CCTV camera in the hallway

Install a keypad lock on the control room door only

A SCADA control center has a motion sensor in the server room that triggers an alarm. One night, the alarm activates, but the CCTV camera in that room is not recording. The security team finds no sign of entry. What is the most likely cause of this gap?

The alarm was a false positive caused by a small animal

The motion sensor is faulty and should be replaced immediately

The CCTV system was not integrated with the alarm system to start recording on alarm

The security team did not respond quickly enough to the alarm

A food processing plant has a large warehouse where the PLCs for the conveyor system are located. The warehouse is dark and has many blind spots. The security team wants to detect an intruder entering the warehouse at night. Which surveillance system is most appropriate?

Install a loudspeaker that plays a recording of a barking dog

Install a single visible-light CCTV camera at the entrance

Use a guard to patrol the warehouse once per hour

Install infrared (IR) motion sensors and CCTV cameras with night vision

A water treatment facility has a control room with a single entrance that also serves as the emergency exit. The facility manager wants to prevent tailgating while still allowing rapid evacuation during an alarm. Which physical control best meets both requirements?

Install a mantrap with interlocking doors that only opens both doors during a fire alarm

Use a high-security lock with a keypad and require all staff to memorize the code

Install a CCTV camera above the door and post a guard to monitor entry

Add a biometric reader on the inside of the door to require authentication for exit
