Which type of door lock is classified as 'fail-safe' in fire egress scenarios?
Answer: Electromagnetic lock that releases when power is cut
Fail-safe locks (like mag-locks) default to the unlocked/open position when power is lost, ensuring egress during fire or power failure.
The concept of 'defense in depth' applied to physical security means:
Answer: Using multiple independent security layers so that failure of one does not compromise the whole
Defense in depth uses concentric, independent security layers so an attacker who defeats one layer still faces additional barriers.
Under the NIST SP 800-116 guidelines for use of PIV credentials, Assurance Level 4 (highest) requires which authentication mechanism at a physical access point?
Answer: Card plus PIN plus biometric (three-factor)
NIST SP 800-116 Assurance Level 4 mandates three-factor authentication: PIV card, PIN, and biometric to achieve the highest identity assurance.
A security consultant recommends 'ballistic-resistant glazing' rated UL 752 Level 3. This rating is designed to stop projectiles from which weapon type?
Answer: .44 Magnum handgun
UL 752 Level 3 is rated for .44 Magnum handgun projectiles; higher levels address higher-powered rifles and submachine guns.
Which document produced during a security design project defines the owner's security objectives, performance criteria, and basis of design decisions?
Answer: Basis of Design (BOD) / Security Narrative
The Basis of Design document records design intent, performance goals, and assumptions—serving as the foundational reference for all subsequent security design decisions.
A risk assessment identifies a high-value server room as a critical asset. The MOST appropriate initial step before selecting security countermeasures is:
Answer: Determine the threat likelihood and impact to calculate risk
Countermeasure selection should be driven by a formal risk calculation (likelihood × impact) to ensure controls are proportionate to actual risk.
In physical security, 'target hardening' refers to:
Answer: Making a specific asset more difficult to attack through reinforcement and barriers
Target hardening involves physical modifications—reinforced doors, locks, bollards, glazing—that increase the effort and time required for an attacker to succeed.
