Internet and Internet Attacks Explained at GRC

Recommended Posts

For an interesting description of the mechanics/electronics of the Internet, have a look at the information Steve Gibson has written at http://www.grc.com. Despite his rather effusive style, he presents the clearest explanation I have yet seen complete with colour diagrams to illustrate the discussion. Most interesting is his description of various types of DOS attacks, DDOS attacks, and the latest DRDDOS attacks.

I tested my window's computers with this sight.

 

With Mc Affee personal firewall running, along with my main firewall, the report was stealth. But it took an additional program to do it. Linux of course was stealth with out any additional effort.

grc was my first exposure to 'security information'. I found it by chance when I bough BlackIce several years ago and was browsing their site. BI had a link to Gibson's 'ShieldsUp" thingy.

 

I've read most, perhaps all of his stuff. Pretty informative in a fire and brimstone kind of way. :twisted: When I first ran ShieldsUp on my old Win95 box I learned about File & Print bindings in TCP/IP. I was showing off everything. :oops: :lol:

Sure I'll change my avatar if it makes anyone uncomfortable but not for the reason that it can trigger a seizure in photosensitive epilepsy. See this site: http://www.epilepsy.org.uk/info/photofrm.html , http://www.epilepsytoronto.org/people/eaup...ate/vol9-3.html , http://dspace.dial.pipex.com/town/park/sk9...actsheet_04.htm ,

http://books.cambridge.org/1898683026.htm , ' http://www.essex.ac.uk/psychology/overlays...epsy%20POT2.htm , and the list goes on.

 

As a retired social psychologist, this topic frequenty came up as the potential sources grew from picket fences from a moving car to the current debate about disco and video games. Out of curiosity, I timed it roughly and the frequency is approximately 1 flicker/1.5 sec., far below that required to trigger a seizure. Unfortunately, this condition has been surrounded in myth in the computer age not unlike other conditions where there is not unanimity in the medical/psychiatric community. These issues have been aggravated by the arrival of some psychotropic drugs consumed by non-photosenstive epileptics causing subsequent seizures in a variety of settings.

 

I am responding to your concern on the extremely remote chance that a photosensitive epileptic might suffer a seizure viewing that avatar. It will be done this afternoon.

 

As a footnote, it should be said that flashing images may figure larger in certain migraine headache sufferers and in persons with brain damage caused by traumatic head injuries.
