Detailed NanoProbe Test Descrptions


The Connection Profile determines and displays several non-obvious aspects of your Internet connection.



What does a "reverse lookup" of your computer's IP address reveal about your identity? Are you statically trackable in this way through your ISP's DNS servers? (Probably so.) What information is being leaked about you? Is your Internet connection being transparently cached and, perhaps, monitored? (Reports are that ISPs are getting in on the profiling act.) Are your secure connections also being proxied and filtered? If you have more than one IP and entered this page with the NanoProbe RSVP Client, how do those multiple connections compare, and which one would you like to use for the other tests? Exactly what sort of IP and port translation (NAT) is being performed by your local network or your ISP? This test answers these questions and more.


This high-speed test checks the standard set of 12 TCP ports probed by the traditional ShieldsUP! test.



It is useful as a quick check-up of any computer's public Internet connection. It checks several ports that any Windows machine will have open to the Internet so it can be used to quickly verify the presence and proper operation of a personal firewall and/or NAT router.


BYOP allows more advanced users to specify which TCP and UDP ports they wish to have remotely checked.



There are many reasons for needing to quickly check the public accessibility of one or more ports that are not checked by our Quick Port Probe. This test reports on the status of any TCP and UDP ports specified by the user. And, as a further convenience to users, their custom port assignments can also (optionally) be saved for repeated use if they choose to accept a benign cookie from this page.


A careful analysis of your machine's received-data acknowledgements allows it to be tuned to achieve maximum Internet performance.



It has long been known that several user-configurable parameters dramatically affect any machine's Internet connection performance. But until now, the determination of their optimal settings has been a time consuming, hit-or-miss proposition. This advanced Internet bandwidth optimizer changes that forever.


This unique test produces a detailed characterization of the Internet packet flow between your computer and the public Internet.



Our NanoProbe Technology is used to insert short-lived, rapidly expiring, (and completely benign) TCP ACK packets into a previously established Internet TCP connection. This allows our Tachyon TraceRoute to silently and undetectably penetrate personal NAT routers and firewalls — and even to trace deeply into private networks — by hijacking the established TCP connection's NAT routing and firewall permissions.



(Note that due to the potency and abuse-prone nature of this test, the use of our spoof-proof RSVP Agent technology will be a prerequisite.)


This test thoroughly exercises and remotely characterizes the capabilities of a machine's Internet firewall.



Standard remote TCP connection tests yield useful first-pass information about a personal firewall, but they determine little more than whether or not the firewall is working. Compared to what's possible, these simple tests fall far short of being comprehensive. This Advanced Firewall Test checks such things as a firewall's connection "statefulness", whether it allows simple ACK tunnelling exploits, how or if it handles fragmented packet reassembly and administrative ICMP traffic, how intelligently it handles IDENT probes, and even whether the connection's nearby upstream routers may be exposing undetected vulnerabilities.



(Note that due to the potency and abuse-prone nature of this test, the use of our spoof-proof RSVP Agent technology will be a prerequisite.)


This reveals the "HTTP headers" your browser is submitting to remote web servers. It also demonstrates the operation of web browser "cookies".



Exactly what information is your web browser giving out with each remote web request? Since a web user's browser headers are invisible, it is difficult to know for sure. This test shows the headers your browser is sending out with web requests.


Quarantine a web page's content for safe examination with your browser.



Have you ever wanted to examine a suspicious or questionable web page URL without clicking on it and taking the risk of actually "going there"? This facility allows you to instruct our server to safely pull the page for you. It is then safely displayed as "dead text" for your examination. From there it may be copied to your own machine for further research.


View several aspects of your web browser's secure connection certificate.



Anonymity is a cherished but increasingly endangered feature of the Internet. Its inevitable loss will bring many benefits, but at a privacy cost that many people may find distressing. This test page currently shows the features of the (currently anonymous) Secure Sockets Layer (SSL) security certificate used to negotiate connections with remote web sites. In the future, as the use of personal digital certificates becomes more prevalent, it will detail the aspects of your identity that are being divulged to any certificating-using secure site.

This NanoProbe Remote Internet Security Analysis Suite is a growing collection of free Internet security-related web based tests. Subscribers to our free GRC Corporate News Blog will be notified when tests are enhanced or added.
