Data at Rest

　　Data at rest is a term that is sometimes used to refer to all data in computer storage while excluding data that is traversing a.network or temporarily residing in computer memory to be read or updated. Data at rest can be archival or reference files that are changed rarely or never; data at rest can also be data that is subject to regular but not constant change. Examples include vital corporate files stored on the hard drive of an employee’s notebook computer, files on an external backup medium, files on the servers of a storage area network (SAN), or files on the servers of an offsite backup service provider. Businesses, government agencies, and other institutions are concerned about the threat posed by hackers to data at rest. In order to keep data at rest from being accessed, stolen, or altered by unauthorized people, security measures such as data encryption and hierarchical password protection are commonly used.

靜止數據

　　靜止數據這個術語有時用來指除正在網絡上傳送的或暫時駐留在計算機內存中準備讀出或更新的數據以外的計算機存儲設備中的所有數據。靜止數據可以是很少或者從來不改變的存檔或參考文件，它們也可以是定期但不是經常更改的數據。（靜止數據的）例子包括儲存在雇員筆記本電腦硬盤上的公司重要文件、外接備份存儲介質上的文件、存儲區域網（SAN）服務器中的文件、或者異地備份服務提供商服務器上的文件。企事業單位、政府部門和其他機構對黑客給靜止數據帶來的威脅十分擔憂。為了防止靜止數據被不法人士存取、竊取或修改，通常采取一些安全措施，如數據加密和分等級的口令保護。
