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. For guidance from the Microsoft Developer Network on how to do this with Always Encrypted: https://msdn.microsoft.com/en-us/library/mt163865.aspx.
Review the system documentation to determine whether the organization has defined the information at rest that is to be protected from modification, which must include, at a minimum, PII and classified information.
If no information is identified as requiring such protection, this is not a finding.
Review the configuration of SQL Server, Windows, and additional software as relevant.
If full-disk encryption is required, and Windows or the storage system is not configured for this, this is a finding.
If database transparent data encryption (TDE) is called for, check whether it is enabled:
SELECT
DB_NAME(database_id) AS [Database Name], CASE encryption_state WHEN 0 THEN 'No database encryption key present, no encryption'
WHEN 1 THEN 'Unencrypted'
WHEN 2 THEN 'Encryption in progress'
WHEN 3 THEN 'Encrypted'
WHEN 4 THEN 'Key change in progress'
WHEN 5 THEN 'Decryption in progress'
WHEN 6 THEN 'Protection change in progress'
END AS [Encryption State]
FROM sys.dm_database_encryption_keys
For each user database for which encryption is called for and it is marked Unencrypted, this is a finding.
If table/column encryption and/or a separation between those who own the data (and can view it) and those who manage the data (but should have no access) is required for PII or similar types of data, use Always Encrypted. The details for configuring Always Encrypted are located here: https://msdn.microsoft.com/en-us/library/mt163865.aspx.
Review the definitions and contents of the relevant tables/columns for the Always Encryption settings, if any of the information defined as requiring cryptographic protection is not encrypted this is a finding.
