Use OCS for FIPS authorization (only): Leave an OCS card in HSM slot. Same passphrase for all cards (2) Leave an OCS card in slot of every HSM in cluster. Same passphrase for all cards (2) Leave an OCS card in HSM slot. Use OCS for credential authorization: (1) Use 1/N quorum. The following table describes the authorization recovery behavior of the nCipher Security World after a temporary outage. The Security World folder permits easy back up or transfer to other legitimate clients that may use the authorized mechanisms to access the encryption keys. Using an Entrust HSM allows the master encryption keys to be kept physically separate from the database it is protecting, and also provides a hardware protected boundary from which encryption keys can never leave in plaintext.Īdditionally, the encryption keys are held in a Security World folder which is also encrypted and is useless to anyone who does not possess the authorized means to access them. The encryption keys that are used to encrypt the database are typically held as part of the database, but these keys are themselves encrypted using a master encryption key in order to protect them. When using TDE, data is not protected by encryption whilst in memory. The database is encrypted again when saved to disk storage. Transparent Data Encryption (TDE) is used to encrypt an entire database in a way that does not require changes to existing queries and applications.Ī database encrypted with TDE is automatically decrypted when the database loads it into memory from disk storage, which means that a client can query theĭatabase within the server environment without having to perform any decryption operations.
