SQL Server must protect data at rest and ensure confidentiality and integrity of data.
An XCCDF Rule
Description
<VulnDiscussion>This control is intended to address the confidentiality and integrity of information at rest in non-mobile devices and covers user information and system information. Information at rest refers to the state of information when it is located on a secondary storage device (e.g., disk drive, tape drive) within an organizational information system. Applications and application users generate information throughout the course of their application use. User-generated data, as well as, application-specific configuration data, needs to be protected. Configurations and/or rule sets for firewalls, gateways, intrusion detection/prevention systems, filtering routers, and authenticator content are examples of system information likely requiring protection. Organizations may choose to employ different mechanisms to achieve confidentiality and integrity protections, as appropriate. If the confidentiality and integrity of SQL Server data is not protected, the data will be open to compromise and unauthorized modification. Protective measures include encryption, physical security of the facility where the storage devices reside, operating system file permissions, and organizational controls. Each of these should be applied as necessary and appropriate.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

Remediation - Manual Procedure
Apply appropriate controls to protect the confidentiality and integrity of data on a secondary device.
Where encryption is required, this can be done by full-disk encryption or by database encryption. To enable database encryption, create a master key, create a database encryption key, and protect it by using mechanisms tied to the master key, and then set encryption on.
Implement physical security measures, operating system access control lists and organizational controls appropriate to the sensitivity level of the data in the database(s).
