I just did a port test on grc.com Discovered that I had many many ports opened.
However, I am not sure how to close the ports... I am running SBS2003. Also, I do not know whether I will be needing the services.
I intend to install ZoneAlarm, but will it block incoming connections? (am a small-scale web server)
so can someone help:
1) tell me how to close the ports
2) tell me which ports is needed for service relevant to me
3) suggest ways to fortify my security features?
