2.1 Physical Access Security

Question 1

What are electronic credentials in physical access control?

Answer 1

Digital access methods such as RFID-enabled badges or key fobs used to unlock doors.

These credentials enhance security and streamline access management.

Question 2

What technology is commonly used in access badges for proximity-based entry?

Answer 2

RFID (Radio Frequency Identification)

RFID technology allows for contactless access to secured areas.

Question 3

What enhancement can be added to access badges for improved security?

Answer 3

Cryptographic certificates for stronger identity verification.

This helps prevent unauthorized access by ensuring the authenticity of the badge.

Question 4

What are mobile digital keys in physical security?

Answer 4

Digital access credentials stored on smartphones used to unlock doors.

They provide convenience and can be managed remotely.

Question 5

How do mobile digital keys increase security?

Answer 5

They leverage the phone’s built-in authentication methods (e.g., device unlock via PIN, biometrics).

This adds an additional layer of security beyond just the key itself.

Question 6

Why are traditional physical keys still used in modern environments?

Answer 6

They provide fail-safe access during power outages and are used for low-traffic or high-security areas.

Physical keys are reliable and do not depend on electronic systems.

Question 7

How are physical keys typically managed in organizations?

Answer 7

Using controlled checkout systems or key cabinets to track usage.

This helps maintain accountability and security over key distribution.

Question 8

What is biometric authentication?

Answer 8

A method of verifying identity using unique physical or behavioral characteristics.

This includes methods like fingerprint, facial recognition, and iris scanning.

Question 9

What is a retina scanner used for?

Answer 9

To identify individuals based on the unique patterns of their retina.

Retina scanning is highly secure due to the uniqueness of retinal patterns.

Question 10

What is fingerprint scanning used for in access control?

Answer 10

To verify identity using unique fingerprint patterns.

Fingerprint scanners are commonly used in various security applications.

Question 11

What does a palm print scanner measure?

Answer 11

The unique patterns of veins and lines in a person’s palm.

This method is similar to fingerprint scanning but uses palm characteristics.

Question 12

What is facial recognition technology (FRT)?

Answer 12

A system that identifies individuals by analyzing facial features.

FRT is increasingly used in security systems for access control.

Question 13

What is voice recognition used for?

Answer 13

Identifying individuals based on unique vocal characteristics.

This technology can be used for secure access to systems and devices.

Question 14

Why is proper lighting important in physical security?

Answer 14

It improves surveillance camera effectiveness and helps deter unauthorized activity.

Good lighting is essential for effective monitoring and crime prevention.

Question 15

What is a magnetometer used for in physical security?

Answer 15

A metal detector used to screen individuals for concealed metallic objects.

Magnetometers are commonly used in security checkpoints.
