I have been amazed recently by the amount of home and corporate firewalls that actually allow rogue traffic through, most of you will have a decent hardware firewall in your router. You also need a software firewall.
Here is a good way to test how secure you are behind your firewall
go to this website https://www.grc.com/x/ne.dll?bh0bkyd2
click on proceed, when the sheildsup page comes up, click on the All Service Ports
tab and the service will attempt to test all major ports on your computer for access.
your computer should pass with all green stealthed ports, if there are any red you have either opened the ports yourself or you do not have sufficient protection, blue means the port is blocked but visible to hacking.
just thought this might be usefull, somr of you may already have other ays of testing.
