SQL Server Audit Logs for Encrypted Backups
Currently you can configure auditing for Backup & Restore Operations, However the audit logs doesn't clearly show if the backup taken was encrypted or not. The backup statement of the operation is caught but it will be hard to parse for Audit Logs Monitoring.
TDE is an important security feature, that will add the value of encrypting backups, so we need to monitor and track confidential database when an unencrypted backup was taken !
my recommendation is to add a new filed in the audit logs to flag if backup generated was encrypted or not....this will greatly enhance security monitoring.
