Hi I have SQL Express 2014

Is it possible to limit process access to a signed program with a digital certificate.
I know you can have login triggers and check for application name, but can you check for the accessing application if it is digitally signed to a company or identity?


Also what is the best way to encrypt the backup from a DB (as with encryption) is not available on SQL Express

Thanks

1. You probably can check encrypt_option
SELECT *
FROM sys.dm_exec_connections
WHERE encrypt_option = 'TRUE'

2. You probably need 3rd Backup tool to encrypt backup for SQL Express.

For the backup encryption if you cannot go to a version/edition that supports backup encryption or TDE you can try encryption from another angle. Things like whole disk encryption of the disks you are writing to, or file-based encryption, like EFS of the directory your backups are going to. Probably depends on what you are trying to accomplish though.
