BitLocker does not have the same performance concerns associated with EFS so it is rmended that you use BitLocker with TDE for defense in depth. As discussed previously, situations exist where memory can be written to disk, such as hibernation or crash dumps. Additionally, other features may write to the disk outside of TDE. BitLocker can be used to mitigate these scenarios. Buy Microsoft SQL Server 2008 Enterprise The primary disadvantages of cell-level encryption are the application changes needed to use it, the performance penalties, and the administration cost. As noted previously, encryption and decryption requires that you use built-ins. This is an entirely manual process and requires the varbinary data type; this means columns must be changed from their original data type to varbinary . For security, the encryption is always salted so the same data will have a different value after encryption. As a result, referential constraints such as foreign keys, and candidate keys such as primary keys do not provide any benefit on these encrypted columns. This also affects query optimization—indexes on the encrypted columns offer no advantage so range and equality searches turn into full table scans. TDE allows full use of indexes and other traditional query optimization tools as well as performing the encryption in bulk. At the root of encryption tree is the Windows Data Protection API (DPAPI), which secures the key hierarchy at the machine level and is used to protect the service master key (SMK) for the database server instance. The SMK protects the database master key (DMK), which is stored at the user database level and which in turn protects certificates and asymmetric keys. These in turn protect symmetric keys, which protect the data. TDE uses a similar hierarchy down to the certificate. The primary difference is that when you use TDE, the DMK and certificate must be stored in the master database rather than in the user database. A new key, used only for TDE and referred to as the database encryption key (DEK) . is created and stored in the user database.

WITH PRIVATE KEY ( Stap 8 Je maakt je wensen en eisen duidelijk en krijgt een persoonlijk advies over jouw mogelijkheden TDE operates at the I/O level through the buffer pool. Thus, any data that is written into the database file (*.mdf) is encrypted. Snapshots and backups are also designed to take advantage of the encryption provided by TDE so these are encrypted on disk as well. Data that is in use, however, is not encrypted because TDE does not provide protection at the memory or transit level. The transaction log is also protected, but additional caveats apply. Exclusieve vacatures All replies TDE See the SQL Server marketing page for descriptions of new features,parison of editions, links to case studies, resources for planning, data sheets, virtual labs, and more. The transaction log is moreplicated. Because the transaction log is designed as a write-once fail safe, TDE does not attempt to encrypt portions of the logs that are already written to disk. Similarly, the log header cannot be re-written because of this write-once principle so there is no guarantee that data that is written to the log even after TDE is enabled will be encrypted. The TDE background scan forces the log to roll over to the next VLF boundary, which allows for the key to be stored in the header. At this point, if the file scan is alsoplete, the DEK state changes to Encrypted and all subsequent writes to the log are encrypted. POSE has core limit of 20.
