ICS Physical Security Operations 2

Question 1

Which physical security control is MOST effective at preventing tailgating into a restricted ICS control room?

Accepted Answer

Mantrap (airlock) vestibule

Answer

A mantrap vestibule enforces one-person-at-a-time entry, physically preventing tailgating regardless of social engineering.

Question 2

An ICS facility wants to detect unauthorized excavation near buried pipeline control cables. Which technology is BEST suited for this?

Accepted Answer

Fiber-optic distributed acoustic sensing (DAS)

Answer

Distributed acoustic sensing detects vibration and mechanical disturbance along buried fiber-optic cable, alerting to unauthorized digging.

Question 3

What is the PRIMARY purpose of a CIKR (Critical Infrastructure and Key Resources) site's visitor management system?

Accepted Answer

Maintain an auditable log of all non-employee access

Answer

Visitor management systems create an auditable record of who entered, when, and under whose escort, supporting accountability and incident investigation.

Question 4

During an ICS security assessment, auditors find that substation doors use padlocks from multiple vendors with varying key grades. What is the BEST remediation?

Accepted Answer

Replace all padlocks with a standardized high-security keyed-alike system

Answer

Standardizing to high-security, keyed-alike padlocks reduces key management complexity and ensures uniform resistance to picking and forced entry.

Question 5

A control room operator notices an unknown person photographing HMI screens through a window. Which immediate response action is MOST appropriate?
