Unfortunately for the author, this analysis is rooted in a faulty conclusion:<p>&quot;Asking around, people assume the TCP handshake verifies the IP addresses on both sides.&quot;<p>Not true - in firewall and security circles this was long ago observed and addressed in many different ways - it is now standard in at least the major Enterprise Firewall Vendors.<p>Still though; the analysis is good, and clearly determined through work, observation, and sound logic. I would work alongside a person like this anytime.<p>If the author can find a venue to assert his findings he&#x2F;she should, but I wouldn&#x27;t expend too much time on it.
