Fix Recommendation

Document and implement procedures to safely back up and store the Service Master Key. Include in the procedures methods to establish evidence of backup and storage, and careful, restricted access and restoration of the Service Master Key. Also, include provisions to store the key off-site.

BACKUP SERVICE MASTER KEY TO FILE = 'path_to_file'
ENCRYPTION BY PASSWORD = 'password';

As this requires a password, take care to ensure it is not exposed to unauthorized persons or stored as plain text.
