Check Text ( C-47955r2_chk )
If physical protections are in place for the data, this is not a finding. Ensure the data is encrypted by executing: SELECT * FROM [master].sys.databases For each user database, ensure the Is_encrypted column is set to 1. If it is not set to 1, this is a finding.

Fix Text (F-46848r2_fix)
Use encryption to protect the data where physical measures are not being utilized. 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.
