Can anyone here please share some steps or process to create secure access for the 3rd party support team ?
I have created the support account called DOMAIN\AS-Support in my AD domain with the member of Domain user only.
I also have placed the support account above as the Local Administrator group in each domain joined application server (about 120 servers)
The support team is then connect with SSL VPN using Juniper SSG, which means after the session authenticated, the support team is using the DOMAIN\AS-Support account to RDP to each of the application server they need to restart & update the software from their own PC at home or office.
However, there is a security problem that my manager don't like, is that the DOMAIN\AS-Support domain account is capable of browsing and enumerating the shared folders in the File server and access them easily.
We do not want this to happens and would like to restrict DOMAIN\AS-Support only to RDP to the allocated server with no other access to any network resources.
How can I do that securely and the best way ?
I have tried to create local account in some of the Application server, so far with the Local account that is put into Local Adminisstrator group in each server, they can do their job properly, but the problem is that I must create the local account in all of the 120 server manually one by one ?
