Many security issues are handled by the Adaptive Server Enterprise authentication and access control mechanisms, ensuring that only properly identified and authorized users can access data. Adaptive Server allows you to mark a column as encrypted and create an encryption key.
An encryption key sets a sequence of data that is required in encrypting other data. The key is also needed when decrypting data.
Encryption functionality in the server versus encryption functionality in the middle tier or any other tier is easier to use, does not require purchase of third-party software, and can be employed with no application changes.
Encrypted columns provide a convenient and robust way to encrypt user data at the column level. Table owners can use the existing Adaptive Server permissions features and password protection to restrict access to data.
To use encryption in Adaptive Server Enterprise requires the license option ASE_ENCRYPTION.
The system security officer enables encryption in Adaptive Server by using:
sp_configure 'enable encrypted columns', 0|1
0 (zero) turns encryption off on the server.
1 (one) turns encryption on for the server.
