2.1 Physical Security

Question 1

What are perimeter security controls used for in physical security?

Answer 1

To prevent unauthorized vehicle and pedestrian access to a facility and protect the outer boundary.

These controls are essential for safeguarding the premises.

Question 2

What are examples of perimeter barriers used in physical security?

Answer 2

• Bollards
• Steel or concrete barricades
• Canals/moats
• High metal fences (sometimes with razor wire)

These barriers help deter unauthorized access.

Question 3

What is the purpose of access control vestibules (man-traps)?

Answer 3

To allow only one person or group to enter a secure area at a time using interlocking doors.

This design enhances security by controlling entry.

Question 4

How do access control vestibules (man-traps) improve security?

Answer 4

They prevent tailgating and ensure controlled, sequential entry into secure areas.

This method is effective in maintaining security protocols.

Question 5

What technologies are commonly used in modern badge-based authentication systems?

Answer 5

• RFID badges
• NFC badges
• Often combined with PINs or biometrics

These technologies enhance access control security.

Question 6

What is the role of multi-factor authentication in physical access control?

Answer 6

It increases security by requiring multiple forms of verification such as a badge plus a PIN or biometric scan.

This method significantly reduces unauthorized access risks.

Question 7

What are examples of biometric authentication methods used in physical security?

Answer 7

• Fingerprint scans
• Retina/iris scans

Biometric methods provide a high level of security.

Question 8

What is CCTV used for in physical security?

Answer 8

Video surveillance to monitor environments and detect suspicious activity.

CCTV systems are crucial for real-time monitoring.

Question 9

What advanced features can modern surveillance cameras include?

Answer 9

• Infrared capability
• Motion detection
• Real-time alerting

These features enhance the effectiveness of surveillance.

Question 10

What are additional sensors often integrated with surveillance systems?

Answer 10

• Door/window sensors
• Other circuit-based intrusion detection devices

These sensors provide comprehensive security coverage.

Question 11

What is the purpose of a duress button?

Answer 11

To allow a user to silently signal an emergency or threat situation.

This feature is vital for personal safety in critical situations.

Question 12

How are server rooms physically secured in data centers?

Answer 12

Using locked cabinets or racks with perforated doors to allow airflow while maintaining security.

This design balances security and equipment functionality.

Question 13

Why do server racks often have perforated doors?

Answer 13

To ensure proper airflow and cooling while still providing physical security.

Maintaining optimal temperature is crucial for server performance.

Question 14

What role do personnel like security guards and receptionists play in physical security?

Answer 14

They verify identities, check access credentials, and monitor entry points.

Human oversight is essential for effective security management.

Question 15

What is an audit trail in physical security?

Answer 15

A recorded log of who enters and exits a facility, including timestamps and access events.

Audit trails are important for accountability and security reviews.
