What is security data at rest?
Security data at rest is data that is stored on a computer system or storage device instead of actively being used or transmitted. It is the data that is stored in a system or device and is not actively in use. This can include data stored on physical media such as disks tapes or USB drives as well as data stored on virtual media such as cloud services applications or databases.
