Descrição

Ensure Database Backups are Encrypted Counts recorded backups in msdb history that were neither backup-encrypted nor taken from a TDE database. Runs one sqlcmd query with its defaults (Windows authentication to the local default instance); set SQLCMDSERVER, SQLCMDUSER and SQLCMDPASSWORD for another instance or SQL authentication. Needs VIEW SERVER STATE / sysadmin-level read access.

Como é verificado

Método de auditoria: Consulta SQL

sql_query

sqlcmd -b -h -1 -W -Q "SET NOCOUNT ON; SELECT COUNT(*) FROM msdb.dbo.backupset b INNER JOIN sys.databases d ON b.database_name = d.name WHERE b.key_algorithm IS NULL AND b.encryptor_type IS NULL AND d.is_encrypted = 0;"

Saída esperada: 0

Como é corrigido

Método de correção: Orientação ou patch de infraestrutura

SQL Server backups need to 'Back up to a new media set', not 'Back up to the existing media set' in order to allow for encryption. The backup option to Encrypt Backup can be implemented after a Certificate or Asymmetric key has been applied to the SQL Server for this purpose. Alternatively, encrypt the database with TDE. This automatically encrypts the backups as well. See 7.5
