TCP/IP Sequence Number Analysis

Posted by michael on from the you-don't-have-to-be-a-kreskin-to-predict-this dept.

johnwbyrd writes "Upon connection via TCP/IP to a host, the host generates an Initial Sequence Number (ISN). It's important to design ISN generation sequences so remote attackers can't predict an ISN (this is called a "blind spoofing" attack). Using phase space analysis you can check the quality of ISNs generated on various OSes. Windows 98's graph is quite pretty."

    I think that's a new record low.

      Why doesn't Slashdot cache pages, images and linked pages (and their images) 1 level deep before posting a link?

      I know this isn't really quite on (this) topic, and it has been said before, but the /. effect is getting stronger than ever. I just hope none of these sites pay for bandwidth.

      This /.ing fix could be easily done, just put the code into slash, do it on the fly.
