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."

    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.
