A pipeline control center has a badge reader at the entrance to the operations floor. An employee forgets their badge and asks a colleague to 'buzz them in' by holding the door open. What is the best way to prevent this behavior?

Post a sign that says 'No Tailgating' and rely on employee awareness

Implement a policy that requires employees to report lost or forgotten badges and use a temporary badge from security

Install a second badge reader inside the door to require authentication for exit

Use a heavier door that closes more slowly

A remote pumping station is located in a rural area with no permanent staff. The station is vulnerable to theft of copper wiring and vandalism of equipment. Which combination of physical controls is most cost-effective for this location?

Deploy a full-time security guard on-site 24/7

Use only CCTV cameras with no recording or monitoring

Rely on the local police to patrol the area regularly

Install a perimeter fence, motion-activated lighting, and tamper alarms on enclosures

A SCADA control center has a video surveillance system that records 24/7, but the recordings are stored locally on a DVR in the same room. During a break-in, the DVR is stolen. What is the most effective improvement?

Increase the resolution of the cameras

Stream video to a remote, secure storage location in real time

Use a hidden DVR in a different part of the building

Which environmental control is essential for protecting ICS equipment from overheating?

Uninterruptible power supply (UPS)

A water treatment plant has a single entrance to the control room. The operator wants to ensure that only authorized personnel can enter, and that tailgating is prevented. The facility already has a badge reader at the door. Which additional control should be implemented to directly address tailgating?

Require all personnel to wear visible ID badges at all times

Increase the number of CCTV cameras in the hallway leading to the control room

Install a mantrap with interlocking doors and a badge reader on the inner door

Add a second badge reader inside the control room to require re-authentication every 30 minutes
