InformationThe backup files will contain all data in the databases. Filesystem permissions and/or encryption should be used to prevent non authorized users from gaining access to the backups.
Backups should be considered sensitive information. If an unauthorized user can access backups then they have access to all the data that is in the database. This is true for unencrypted backups and for encrypted backups if the encryption key is stored along with the backup.
NOTE: Nessus has not performed this check. Please review the benchmark to ensure target compliance.
SolutionImplement encryption, properly restrict filesystem permissions, protect and backup encryption keys.
