In the context of cloud security, "data at rest" specifically refers to data that is not actively moving and is not being used or processed. This includes any type of stored data, such as databases, files, and other forms of information that are saved on physical or virtual storage devices, but remain idle and stationary.

Understanding this concept is crucial for implementing effective security measures, as data at rest is often a target for unauthorized access or breaches. It can be stored in various forms, including backups, snapshot archives, or in databases where data remains until it is retrieved or manipulated.

On the contrary, data actively being processed describes data that is currently in use or being manipulated. Data stored on physical servers is a broader category that could include data at rest, but does not specifically define the state of inactivity of that data. Data transmitted over secure channels, meanwhile, refers to data actively in transit across networks, which is distinctly different from data at rest. Thus, the focus on non-active data correctly categorizes the state of data at rest in cloud security.
