Because of its nature data at rest is of increasing concern to businesses, government agencies and other institutions. [4] Mobile devices are often subject to specific security protocols to protect data at rest from unauthorized access when lost or stolen [7] and there is an increasing recognition that database management systems and file servers should also be considered as at risk; [8] the ...
Encryption scrambles and unscrambles your data to keep it protected. • A public key scrambles the data. • A private key unscrambles the data. Credit card security. When you make a purchase on AOL, we'll only finish the transaction if your browser supports SSL.
Sending backups off-site also ensures that there is a copy of pertinent data that is not stored on-site. Although some organizations manage and store their own off-site backups, many choose to have their backups managed and stored by third parties who specialize in the commercial protection of off-site data.
The backup data needs to be stored, requiring a backup rotation scheme, [4] which is a system of backing up data to computer media that limits the number of backups of different dates retained separately, by appropriate re-use of the data storage media by overwriting of backups no longer needed. The scheme determines how and when each piece of ...

Encryption should be at least 256 bits, and the user should have the option of using his own encryption key, which should never be sent to the server. Network backup A backup service supporting network backup can back up multiple computers, servers or Network Attached Storage appliances on a local area network from a single computer or device ...
The data on the disk should remain confidential. Data retrieval and storage should both be fast operations, no matter where on the disk the data is stored. The encryption method should not waste disk space (i.e., the amount of storage used for encrypted data should not be significantly larger than the size of plaintext).
Note that this does not imply that the encrypted disk can be used as the boot disk itself; refer to pre-boot authentication in the features comparison table. Partition: Whether individual disk partitions can be encrypted. File: Whether the encrypted container can be stored in a file (usually implemented as encrypted loop devices).
