I really know nothing about securing or configuring a ‘live’ internet facing web server and that’s exactly what I have been assigned to do by management. Aside from the operating system being installed (and windows update), I haven’t done a thing. I have read some guides from Microsoft and on the web, but none of them seem to be very comprehensive/ up to date. Google has failed me.
We will be deploying a MVC ASP.NET site.
What is your personal check when you are getting ready to deploy a application on a new windows server?
This is all we do:
Make sure Windows Firewall is enabled. It has an ‘off by default’ policy, so the out of box rule setup is fairly safe. But it never hurts to turn additional rules off, if you know you’re never going to need them. We disable almost everything except for HTTP on the public internet interface, but we like Ping (who doesn’t love Ping?) so we enable it manually, like so:
netsh firewall set icmpsetting 8Disable the Administrator account. Once you’re set up and going, give your own named account admin rights. Disabling the default Administrator account helps reduce the chance (however slight) of someone hacking it. (The other common default account, Guest, is already disabled by default.)
Avoid running services under accounts with administrator rights. Most reputable software is pretty good about this nowadays, but it never hurts to check. For example, in our original server setup the Cruise Control service had admin rights. When we rebuilt on the new servers, we used a regular account. It’s a bit more work (you have to grant just the rights necessary to do the work, instead of everything at once) but much more secure.
