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."
