Answer 14

ACLs control the flow of traffic in and out of a network by defining which users or systems can access resources on a network.

Question 15

What is Multifactor Authentication (MFA) and its significance?

Answer 15

MFA enhances security by requiring multiple forms of verification from independent categories of credentials to authenticate a user’s identity.

Question 16

Describe the role of Mobile Device Management (MDM) in security.

Answer 16

MDM allows IT administrators to manage and secure corporate data on employees’ mobile devices, enforcing policies and securing data.

Question 17

What is the function of a domain in Active Directory?

Answer 17

It is a collection of nodes under a single security boundary within an Active Directory environment, organizing and managing a group of assets like users and computers.

Question 18

How does the Group Policy feature in Active Directory enhance security?

Answer 18

It allows for centralized management of user and computer settings in an AD environment, applying security policies across the network.

Question 19

What is the purpose of home folders in Active Directory?

Answer 19

To centralize the storage of user data on a network server, making management and backup more efficient.

Question 20

Explain the use of folder redirection in Windows environments.

Answer 20

Folder redirection helps redirect the path of a folder to a new location, typically a server, to centralize files and facilitate backups and synchronization.

Question 21

What is the role of security groups in Active Directory?

Answer 21

Security groups allow for the assignment and management of access rights to resources across a network, simplifying the administration of permissions.

Question 22

What does the login script in Active Directory do?

Answer 22

It automates tasks such as mapping network drives and connecting printers upon user login, streamlining user access to network resources.

Question 23

How does a retina scanner improve security?

Answer 23

By scanning the unique patterns of a user’s retina, it provides highly accurate biometric authentication for access control.

Question 24

Why is adequate lighting important in security?

Answer 24

It enhances visibility, deterring unauthorized access and enabling better monitoring through surveillance systems.

Question 25

What security purpose do magnetometers serve at entry points?

Answer 25

They detect metal objects on persons entering a facility, preventing weapons or other unauthorized metallic objects from being brought inside.

Question 26

Describe the role of hard tokens in authentication.

Answer 26

Hard tokens generate a code used in MFA systems, providing a physical device that a user must possess to authenticate.

Question 27

What is the purpose of soft tokens in security?

Answer 27

Soft tokens generate a secure login code through an app on a user’s device, providing a form of authentication that is tied to the user’s possession of the device.

Question 28

How does SMS-based authentication work?

Answer 28

It sends a one-time code to a user’s mobile phone via text message, which they must enter to complete authentication.

Question 29

What are the advantages and risks of voice call authentication?

Answer 29

It provides an additional layer of security by delivering a code via a phone call; however, it shares similar security vulnerabilities to SMS, such as interception or phone number hijacking.
