Have you tested your shields lately?

The folks at GRC have created a web-based scanner that will tell you exactly how secure (or insecure) your connection to the internet is (or isn’t). Click on over and you’ll find ShieldsUP listed under Services at GRC.com

Here’s what they have to say about their scan…

This Internet Common Ports Probe attempts to establish standard TCP Internet connections with a collection of standard, well-known, and often vulnerable or troublesome Internet ports on YOUR computer. Since this is being done from our server, successful connections demonstrate which of your ports are “open” or visible and soliciting connections from passing Internet port scanners.

The ShieldsUP scan is one of the tools I use and recommend, (along with lots of other offerings from GRC.com more on those later). It takes a minute or so to run the port probe, but the satisfaction that your internet connection is secure is well worth the wait. And if your connection is insecure you will get detailed information on the open ports, what the risks are, and what you can do about it.

Head on over and run the scan. If you don’t get a “True Stealth” rating let me know and I’ll see if I can help. Here’s the results of my most recent scan…

Your system has achieved a perfect “TruStealth” rating. Not a single packet — solicited or otherwise — was received from your system as a result of our security probing tests. Your system ignored and refused to reply to repeated Pings (ICMP Echo Requests). From the standpoint of the passing probes of any hacker, this machine does not exist on the Internet. Some questionable personal security systems expose their users by attempting to “counter-probe the prober”, thus revealing themselves. But your system wisely remained silent in every way. Very nice.

As you can see, the results are written in a clear and friendly style. Gibson Research Corporation is another one of the good guys out there helping to tame the wild and woolly internet for folks like you and me. Now go check your shields.
