From the query prompt: SELECT name FROM [master].sys.databases WHERE state = 0 Repeat for each database: From the query prompt: USE [database name] SELECT s.name, k.crypt_type_desc FROM sys.symmetric_keys s, sys.key_encryptions k WHERE s.symmetric_key_id = k.key_id AND k.crypt_type IN ('KSKP', 'ESKS') AND s.principal_id <> 1 ORDER BY s.name, k.crypt_type_desc Review any symmetric keys that have been defined against the System Security Plan. If any keys are defined that are not documented in the System Security Plan, this is a finding. Review the System Security Plan to review the encryption mechanism specified for each symmetric key. If the method does not indicate use of certificates, this is a finding. If the certificate specified is not a DoD PKI certificate, this is a finding. |

Configure or alter symmetric keys to encrypt keys with certificates or authorized asymmetric keys: From the query prompt: ALTER SYMMETRIC KEY [key name] ADD ENCRYPTION BY CERTIFICATE [certificate name] ALTER SYMMETRIC KEY [key name] DROP ENCRYPTION BY [password, symmetric key or asymmetric key] The symmetric key must specify a certificate or asymmetric key for encryption. |
