In cybersecurity, what does the term 'data at rest' refer to?

Data actively being used by applications
Data stored on devices
Data being transmitted over the network
Data being backed up

The correct answer is: Data stored on devices

The term 'data at rest' refers specifically to data that is stored on devices and is not actively moving between devices or being processed. This includes data saved on hard drives, databases, and other storage media, where it remains idle until accessed or modified. Understanding this concept is critical in cybersecurity, as data at rest is a common target for attackers who may seek to exploit vulnerabilities in storage systems or unauthorized access to sensitive information. The other options pertain to different states of data: data actively used by applications is often referred to as 'data in use,' while data being transmitted over a network would be classified as 'data in transit.' Data being backed up can overlap with data at rest, but it encompasses the process of creating copies of data for recovery purposes rather than the nature of the data itself when it is simply stored.
