Read the first 7 Physical Security flashcards as text

  1. Which fire suppression agent is MOST appropriate for a server room to minimize equipment damage?

    Answer: Clean agent (e.g., FM-200)

    Clean agents like FM-200 suppress fire without leaving residue or causing electrical damage, making them ideal for data centers.

  2. A security audit finds that terminated employees' access badges are not being deactivated promptly. Which process addresses this?

    Answer: Establishing an offboarding procedure that includes immediate badge deactivation

    A formal offboarding process that immediately revokes physical access credentials prevents unauthorized entry by former employees.

  3. What is the MAIN security advantage of using a biometric system over a PIN-based access system?

    Answer: Biometric credentials cannot be shared or stolen as easily as PINs

    Biometric credentials are tied to an individual's unique physical traits, making them far harder to share, guess, or steal than PINs.

  4. An organization wants to protect its perimeter from vehicle ramming attacks. Which control is MOST effective?

    Answer: Bollards or concrete barriers

    Bollards and reinforced concrete barriers physically stop vehicles and are specifically rated to withstand ramming attacks.

  5. Which environmental control is CRITICAL to preventing hardware failures in a data center?

    Answer: Proper temperature and humidity control (HVAC)

    Maintaining proper temperature and humidity prevents overheating and static discharge, the primary environmental causes of hardware failure.

  6. A visitor arrives at a secure facility and is escorted to a meeting room. Which physical security principle does escorting visitors implement?

    Answer: Least privilege through physical supervision

    Escorting visitors ensures they only access areas necessary for their purpose and cannot roam unsupervised, enforcing least privilege physically.

  7. What does the term 'dead man's door' refer to in physical security?

    Answer: A mantrap that traps an intruder once unauthorized entry is detected

    A dead man's door (or mantrap) captures a person between two interlocked doors when unauthorized access is detected, preventing entry or exit.
