Answer explanation

Data in motion is NOT a state in which data exists within a network. The other options - data at rest, data in transit, and data in use - are valid states of data within a network.

What is data at rest?

• Data that is actively being processed and accessed by an app or user

• Data that is actively moving/transmitted over a network

• Stored data that is not being used

• Data that is being used or transmitted

Answer explanation

Stored data that is not being used is referred to as data at rest, as it is not actively being processed or accessed.

Which of the following measures is commonly used to secure data stored on devices or servers?

• Data masking

• Full-Disk Encryption (FDE)

• Data obfuscation

• Data anonymization

Answer explanation

Full-Disk Encryption (FDE) is commonly used to secure data stored on devices or servers by encrypting the entire disk, making it inaccessible without the proper decryption key.

What does protecting data at rest involve?

• Data masking and data obfuscation

• Encryption, access controls, authentication, and physical security

• Data anonymization and data masking

• Data obfuscation and data anonymization

Answer explanation

Protecting data at rest involves encryption, access controls, authentication, and physical security.

What does "data in transit" refer to?

• Data that is actively moving or being transmitted over a network or communication channel.

• Data that is stored in a database.

• Data that is being processed by an application.

• Data that is stored on a hard drive.

What does "data in use" refer to?

• Data that is actively being processed, accessed, or utilized by an application or a user.

• Data that is stored in a database.

• Data that is being transmitted over a network.

• Data that is stored on a hard drive.

Answer explanation

Data in use refers to data that is actively being processed, accessed, or utilized by an application or a user, making it the correct choice.

Which of the following is a protective measure for data in use?

• Data encryption

• Network firewalls
