Which concept in physical security mirrors the 'defense in depth' principle by using multiple layers of physical barriers?
Answer: Layered concentric zones of physical protection
Layered concentric zones (perimeter → outer building → inner areas → critical assets) ensure that an attacker must defeat multiple controls to reach a target, mirroring defense in depth.
What physical security threat does 'dumpster diving' represent?
Answer: Searching discarded materials for sensitive information such as documents or storage media
Dumpster diving involves searching through an organization's discarded trash to find sensitive information such as organizational charts, passwords, or financial data.
What is the purpose of a 'hot aisle/cold aisle' configuration in a data center?
Answer: To manage airflow and cooling efficiency by organizing equipment orientation
Hot aisle/cold aisle configurations align server racks so that cold air is drawn in from the front (cold aisle) and hot exhaust air exits from the back (hot aisle), optimizing cooling efficiency.
What is TEMPEST in the context of physical and information security?
Answer: A set of standards addressing unintentional electromagnetic emissions from electronic equipment that could reveal data
TEMPEST refers to government standards for protecting against the unintentional electromagnetic emissions from electronic devices that could be intercepted to reconstruct data being processed.
Which physical control best describes a fence, wall, or locked door used to stop unauthorized access before it occurs?
Answer: Preventive control
Fences, walls, and locked doors are preventive controls because they physically stop or deter unauthorized access before it can occur.
What environmental physical security control is critical for preventing hardware damage from electrostatic discharge (ESD) in server rooms?
Answer: Anti-static flooring and grounding straps
Anti-static flooring and grounding straps dissipate static electricity before it can discharge into sensitive electronic equipment, preventing hardware damage from ESD.
What is the security principle behind requiring employees to wear visible identification badges at all times within a facility?
Answer: Accountability and identification of authorized personnel
Requiring visible badges ensures that all individuals inside a facility can be identified as authorized or unauthorized, supporting accountability and enabling staff to challenge individuals without badges.
