Read the first 7 Physical Security Operations flashcards as text

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

    Answer: Mantrap (airlock) vestibule

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

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

    Answer: Fiber-optic distributed acoustic sensing (DAS)

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

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

    Answer: Maintain an auditable log of all non-employee access

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

  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?

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

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

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

    Answer: Contact security personnel and document the incident

    Contacting security and documenting the incident ensures a trained response while preserving evidence without personal risk to the operator.

  6. Which lighting standard is MOST commonly referenced for securing the perimeter of US critical infrastructure facilities at night?

    Answer: IESNA RP-33 Security Lighting

    IESNA RP-33 provides recommended practices for security lighting, including lux levels for perimeters, parking areas, and building entrances.

  7. What is 'crime prevention through environmental design' (CPTED) and how does it apply to ICS facilities?

    Answer: Designing the physical environment to deter unauthorized access and criminal behavior

    CPTED uses natural surveillance, access control, and territorial reinforcement through facility design to deter threats before they reach ICS assets.
