PSP Access Control Systems 1 — Questions and Answers
Question 1: Which access control model grants permissions based on a subject's clearance level and the sensitivity classification of the object?
- Discretionary Access Control (DAC)
- Mandatory Access Control (MAC) (Correct answer)
- Role-Based Access Control (RBAC)
- Attribute-Based Access Control (ABAC)
Correct answer: Mandatory Access Control (MAC)
Mandatory Access Control (MAC) enforces access based on security labels assigned to subjects and objects, commonly used in government and military environments.
Question 2: What is the primary purpose of a mantrap (access control vestibule) in a physical security system?
- To provide emergency egress
- To prevent tailgating and piggybacking (Correct answer)
- To house security personnel
- To store access control credentials
Correct answer: To prevent tailgating and piggybacking
A mantrap uses two interlocking doors to ensure only one person passes through at a time, preventing unauthorized tailgating or piggybacking.
Question 3: Which card technology offers the highest level of security for access control credentials?
- Magnetic stripe
- Proximity (125 kHz)
- Smart card (contact/contactless) (Correct answer)
- Wiegand wire
Correct answer: Smart card (contact/contactless)
Smart cards use encrypted microprocessors that make them significantly more resistant to cloning and counterfeiting compared to magnetic stripe or proximity technologies.
Question 4: In access control, what does the term 'two-person integrity rule' require?
- Two guards must patrol together at all times
- Two authorized individuals must be present to access a sensitive area (Correct answer)
- Two separate authentication factors must be used
- Two supervisors must approve access requests
Correct answer: Two authorized individuals must be present to access a sensitive area
The two-person integrity rule requires at least two authorized individuals to be present simultaneously when accessing sensitive areas or materials, reducing insider threat risk.
Question 5: What is the recommended minimum door thickness for a high-security access-controlled door to resist forced entry?
- 1-3/4 inches (44mm) (Correct answer)
- 1-3/8 inches (35mm)
- 1 inch (25mm)
- 2-1/4 inches (57mm)
Correct answer: 1-3/4 inches (44mm)
ANSI/SDI standards recommend a minimum 1-3/4 inch (44mm) solid-core door for high-security applications to provide adequate forced-entry resistance.
Question 6: Which biometric identifier is considered the MOST unique and stable over time for access control purposes?
- Fingerprint
- Hand geometry
- Iris pattern (Correct answer)
- Voice recognition
Correct answer: Iris pattern
The iris pattern is considered the most unique and stable biometric identifier because it is protected inside the eye and does not change significantly with age.
