I wanted to know if there's a best practice in regards to secure a large environment of SQL Server instances (version 2000-2012).
Currently the SQL services are running with many users and I'm trying to improve the situation. I know that the best practice is to use a domain account.
But what is the best practice for a large environment ? Should I create a domain user that will be the service account for each service? For each Server? For the entire list of servers?
I would be happy to hear from your experience,
Thanks,
Roni.
