There is and never will be a link that can secure your DB, not 100% atleast, some steps you can take is closeing the MSSQL port, makeing sure all scripts on your website are secure, makeing sure your VPS RDP accounts have a lockout clause, ETC, just google some of these things, or as I said, give me something spesific to help you with, I won't cover everything at once, as that would be a HUGE thread..lol..
