How to identify inbound traffic for Windows 7 and block ports as nessecary.
Greetings,
I'm running Windows 7 on an Acer laptop. I'm trying to become knowledgeable of network security. In the process I downloaded CurrPorts to identify and kill 'Unknown' connections. Long story short, CurrPorts is about good for nothing in this regard. Each and every attempt to kill a connection fails with a line that says I must be running it as Administrator when I am running as Administrator.
At anyone time I can have 30+ 'Unknown' connections. This is frustrating. Yes, I do get the IP or domain name and see who the connection is from. Yes, many are from Google or AOL etc but many are not. I find some connections are from all over the world and have nothing to do with what I'm using the browser for.
How can a manage these connections better? How can I reduce the amount of unknown connections? For instance, if I'm using Google or AOL or G mail, these are the only unknowns I want connecting to my computer.
I did use Windows Firewall with Advanced Security to set a few rules but these rules appear to be good for nothing seeing how there are so many potential Unknown connections.
Thanks for the help!

Thank you Mr. Hurst.
I'm guessing both of these are free-ware? Back in 2006 (my last IT days) a sniffer was in the thousands of dollars.
Given they are free, would you be so kind as to provide what you call a 'safe' download site/link. Sometimes 90 % of the battle in obtaining good free ware is getting it from a site that doesn't find a means to installing a Trojan.

Thanks guys!!
You are very welcome and good luck with Network Security.
For instance, if I'm using Google or AOL or G mail, these are the only unknowns I want connecting to my computer.Can you post a useful sample of the "unknown" connections? Using any of those three is likely to give a fair number of "unknown" connections in order for them to work well (or perhaps at all).
Also, are you asking about any connections or only in-bound? Also, what router/modem equipment is under your control?
I use Comm View (Tamosoft) but Wire Shark also works.
Comm View will show you the ports uses with the IP address.
