Dear all,

We are using DBSec to enrypt the database data but the ecrypted database data are owned by one user.

As we think that DBA can change the password of the user, then the DBA can also access these sensitive data.

Is there any method to prevent this case ?

Please advice.

Denise

If the data are encrypted what is the problem?
Is this not the purpose of encryption to prevent from knowing what are the data even if they are stealed?

Hi,

The purpose of guarding the DBA from changing the password of the user account controlling the encrypted data in order to prevent the DBA to access the sensitive information.

Thanks.

You repeat the same sentence, I repeat mine:
Which sensitive information? If the data are encrypted then no one has access to sensitive information just to encrypted data which can't be considered as sensitive unless you have a poor encryption algorithm.

By the way, DBA does not need access to a user to get data in any of his tables.
