Sorry to interrupt the v6 chaos discussion, but I figured that this might be of some interest to folks on the list. Since the IESG, IAB, etc. has forward this to the RFC Editor queue to be published as an Informational RFC, I think is a good thing. One thing, however, that troubles me, is the title -- which I think is somewhat misleading. While I think it is a fine and thorough document, it is really not about mitigating TCP SYN flooding attacks, really, but more about lowering the threshold of pain. In any event... it's a nice document. :-) FYI, - ferg [forwarded message] From: The IESG <iesg-secretary@ietf.org> To: IETF-Announce <ietf-announce@ietf.org> Date: Thu, 31 May 2007 10:07:00 -0400 The IESG has approved the following document: - 'TCP SYN Flooding Attacks and Common Mitigations ' <draft-ietf-tcpm-syn-flood-05.txt> as an Informational RFC This document is the product of the TCP Maintenance and Minor Extensions Working Group. The IESG contact persons are Lars Eggert and Magnus Westerlund. A URL of this Internet-Draft is: http://www.ietf.org/internet-drafts/draft-ietf-tcpm-syn-flood-05.txt Technical Summary This document describes TCP SYN flooding attacks, which have been well-known to the community for several years. Various countermeasures against these attacks, and the trade-offs of each, are described. This document archives explanations of the attack and common defense techniques for the benefit of TCP implementers and administrators of TCP servers or networks. Working Group Summary The consensus within the TCPM WG to publish this document as an informational RFC is strong. Protocol Quality This document details several techniques that have been used in TCP implementations for many years. The technology discussed in this document is not new, but rather this document is helping the RFC-series "catch up" with common practice and details experience with several mechanisms. Personnel The document shepherd for this document is Mark Allman (TCPM co-chair). The responsible AD is Lars Eggert. _______________________________________________ IETF-Announce mailing list IETF-Announce@ietf.org https://www1.ietf.org/mailman/listinfo/ietf-announce [end] -- "Fergie", a.k.a.
