You can use Sysinternals TCPView application which gives you a nice graphical view of all of the network connections on your system.

I prefer this one to Sysinternals TCPView because it have filters and logs features

Comodo Firewall

In "Custom Policy Mode" you will be prompted for authorization each time a program create a connection...
