"Data at rest" specifically refers to data that is stored on a physical medium, such as hard drives, SSDs, or any other storage device. This encompasses any data that is not actively being used or processed but is instead saved for future access or reference. The concept of "data at rest" is crucial for understanding data security and compliance, as it often requires specific protection measures to safeguard the information when it is not in transit or actively engaged in processing. This includes encryption, access controls, and overall security policies to prevent unauthorized access. The other options address different states of data. For instance, data actively in use by a server refers to "data in use," indicating that this data is currently being processed or manipulated. On the other hand, data being transmitted over a network is known as "data in transit." Understanding these distinctions is key for deploying appropriate security measures based on how data is handled at any given moment.
