Information
Backup and recovery of the certificate used for encryption is critical to the complete recovery of the database. Not having this key can lead to loss of data during recovery.
NOTE: Nessus has not performed this check. Please review the benchmark to ensure target compliance.
Solution
Document and implement procedures to safely back up and store the Certificate used for encryption. Include in the procedures methods to establish evidence of backup and storage, and careful, restricted access and restoration of the Certificate. Also, include provisions to store the backup off-site.
BACKUP CERTIFICATE 'CertificateName' TO FILE = 'path_to_file' WITH PRIVATE KEY (FILE = 'path_to_pvk', ENCRYPTION BY PASSWORD = 'password');
As this requires a password, ensure it is not exposed to unauthorized persons or stored as plain text.
