&gt; Subject: IETF Draft on Transmission Control Protocol security

&gt;
&gt; &gt;From the Abstract:
&gt;
&gt;     TCP (RFC793 [1]) is widely deployed and one of the most often used
&gt;     reliable end to end protocols for data communication. Yet when it was
&gt;     defined over 20 years ago the internet, as we know it, was a
&gt;     different place lacking many of the threats that are now common.
&gt;     Recently several rather serious threats have been detailed that can
&gt;     pose new methods for both denial of service and possibly data
&gt;     injection by blind attackers. This document details those threats and
&gt;     also proposes some small changes to the way TCP handles inbound
&gt;     segments that either eliminate the threats or at least minimize them
&gt;     to a more acceptable level.
