We have setup a PC with Windows Server 2003 SP2. It is connected to the internet and runs an SVN server.
Since we are no Windows Server people, we do not know how secure an out-of-the-box Windows 2003 SP2 is. The IP is not public. However if the IP is revealed to public by accident, it can be attacked. We are concerned about somebody getting access to the SVN somehow.
What are the most important security measures on a Windows Server ?
Additionally, are there any ways of getting notified when somebody other than us tries to login to the server ?
