Large Number of Blocked Inbound TCP connections

Greetings.

 

I was checking through my Securuity History, and noticed that there have been a high number of attempted inbound TCP connections to a variety of unused ports.  (Sample below)

 

Category: Firewall - Activities
Date & Time,Risk,Activity,Status,Recommended Action,Category
12/26/2011 10:57 AM,Info,"Unused port blocking has blocked communications. Inbound TCP connection from 222.186.25.148, local service  Port (9415) .",Detected,No Action Required,Firewall - Activities

 

Checking the IP addresses involved, they seem to originate primarily in China, with a few coming out of Europe.

 

I understand that these log entries are showing that Norton is doing its job (kudos!), but how do I know that there aren't successful attempts on ports in use?  Is there a way to see or log port activity?

 

Thanks for any reassurance/assistance.
