Physical Security

Question 1

What is the primary purpose of Physical Security?

Answer 1

Measures to protect tangible assets (buildings, equipment, people) from harm or unauthorized access

Physical security encompasses various strategies and tools to safeguard physical assets.

Question 2

Name two types of Security Controls.

Answer 2

• Fencing
• Bollards

These controls are fundamental tools used to protect physical assets.

Question 3

What are Bollards?

Answer 3

Short, sturdy vertical posts controlling or preventing vehicle access

Bollards are typically made of steel or concrete.

Question 4

What is the function of Fences in physical security?

Answer 4

Barriers made of posts and wire or boards to enclose or separate areas

Fences provide a visual deterrent and establish a physical barrier against unauthorized entry.

Question 5

What is a Brute Force Attack?

Answer 5

Type of attack where access to a system is gained by trying all possibilities until successful

In physical security, this can involve forcible entry or tampering with security devices.

Question 6

What are the components of a Surveillance System?

Answer 6

• Video surveillance
• Security guards
• Lighting
• Sensors

Surveillance systems are organized strategies to observe and report activities.

Question 7

What is an Access Control Vestibule?

Answer 7

Double-door system electronically controlled to allow only one door open at a time

This system helps prevent piggybacking and tailgating.

Question 8

What types of Door Locks are commonly used?

Answer 8

• Padlocks
• Pin and tumbler locks
• Numeric locks
• Wireless locks
• Biometric locks
• Cipher locks
• Electronic access control systems

Each type serves to restrict access and enhance security.

Question 9

What is Access Badge Cloning?

Answer 9

Copying the data from an RFID or NFC card or badge onto another card or device

This can lead to unauthorized access if not properly secured.

Question 10

Fill in the blank: ________ is a method of bypassing surveillance systems by blocking the camera’s line of sight.

Answer 10

Visual Obstruction

This can involve spraying paint or placing objects in front of the camera.

Question 11

True or false: Tampering with security devices involves manipulating them to create vulnerabilities.

Answer 11

TRUE

This can lead to security breaches if not addressed.

Question 12

What are the four categories of sensors used in security?

Answer 12

• Infrared Sensors
• Pressure Sensors
• Microwave Sensors
• Ultrasonic Sensors

Sensors detect and respond to changes in the environment.

Question 13

What is the difference between Piggybacking and Tailgating?

Answer 13

Piggybacking involves consent from the person with legitimate access; Tailgating does not

Both are security risks in access control situations.

Question 14

What is a Cipher Lock?

Answer 14

Mechanical locks with numbered push buttons, requiring a correct combination to open

Commonly used in high-security areas like server rooms.

Question 15

What are the authentication methods used in modern electronic door locks?

Answer 15

• Identification Numbers
• Wireless Signals
• Biometrics

These methods enhance security by requiring specific credentials for access.

Question 16

What is the Crossover Error Rate (CER)?

Answer 16

A balance between False Acceptance Rate (FAR) and False Rejection Rate (FRR) for optimal authentication effectiveness

It is crucial for evaluating biometric systems.

Question 17

What is the purpose of Lighting in surveillance?

Answer 17

Enhances the quality of video recordings and deters criminals

Well-lit areas reduce shadows and hiding spots.

Question 18

What is Interfering with Acoustics in the context of surveillance systems?

Answer 18

Jamming or playing loud music to disrupt the microphone’s functionality

This can prevent effective monitoring of conversations.

Question 19

What is the role of Security Guards in surveillance?

Answer 19

Provide flexible and adaptable forms of surveillance, reassuring staff and customers

They also assist in monitoring and responding to incidents.
