Title

SQL Server must implement cryptographic mechanisms to prevent unauthorized modification of organization-defined information at rest (to include, at a minimum, PII and classified information) on organization-defined information system components.

Description

<VulnDiscussion>Database management systems (DBMSs) handling data requiring "data at rest" protections must employ cryptographic mechanisms to prevent unauthorized disclosure and modification of the information at rest. These cryptographic mechanisms may be native to SQL Server or implemented via additional software or operating system/file system settings, as appropriate to the situation. Selection of a cryptographic mechanism is based on the need to protect the integrity of organizational inf...

Where full-disk encryption is required, configure Windows and/or the storage system to provide this. Where transparent data encryption (TDE) is required, create a master key, obtain a certificate protected by the master key, create a database encryption key and protect it by the certificate, and then set the database to use encryption. For guidance from MSDN on how to do this: https://msdn.microsoft.com/en-us/library/bb934049.aspx. Where table/column encryption is required, enable encryption on the tables/columns in question.
