Just revoke sysadmin from that user role.
Grant revoke on all db's except the required database.

Grant appropriate SELECT, INSERT, UPDATE, DELETE, EXECUTE,... privileges as required on the objects as required.

This should suffice..

The vendor really need sysadmin as the role of the user. He needs to run some special scripts. We have a lot of databases on our production server. How to prevent the vendor with sysadmin role from accessing other databases?
Thanks!

<<The vendor really need sysadmin as the role of the user. He needs to run some special scripts>>

Just out of curiosity what scripts does the vendor run that require sysadmin permissions?

Some scripts about replication server setting. How to prevent them to access other databases and bounce the instance?

 

by: SireesPosted on 2009-08-11 at 13:29:29ID: 25073039

Those scripts will change the settings on the entire server. In a production environment where you have mutilple databases on a server, you should not give the vendors sysadmin permisions.

If I were you, I would ask the vendors to send the scripts so the DBA can run those on the server and remove them from sysadmin permisisons.

>> The vendor really need sysadmin as the role of the user. He needs to run some special scripts. We have a lot of databases on our production server.

If that user belongs to sysadmin, then that user will have system admin ( meaning administrating the entire system). So no way you can revoke access for that user to other databases...
