I just launched my first server with go-grid (cloud). Its a 2GB instance running Windows Server 2008 (64-bit) version. I've installed the IIS components that I'll need along with SQL Express 2008 for the websites that I'll be hosting on there.
I'm a developer by trade and server hardening/security are completely foreign to me. What are the things that I should do next to improve the security on the server?
