Folks,

Based on the recent discussion we have had about ICMP-based DoS attacks,
we have posted an I-D which describes and suggests that network ingress
filtering be applied on ICMPv4 and ICMPv6 error messages (based on the
addresses of the embedded payload).

The I-D is available at:
<http://www.ietf.org/internet-drafts/draft-gont-opsec-icmp-ingress-filtering-00.txt>

Any feedback will be very appreciated.

Thanks!

Best regards,
Fernando

ICMP/ ICMPv6 Error Messages

Abstract:
   Over the years, a number of attack vectors that employ forged ICMP/
   ICMPv6 error messages have been disclosed and exploited in the wild.
   The aforementioned attack vectors do not require that the source
   address of the packets be forged, but do require that the addresses
   of the IP/IPv6 packet embedded in the ICMP/ICMPv6 payload be forged.
   This document discusses a simple, effective, and straightforward
   method for using ingress traffic filtering to mitigate attacks that
   use forged addresses in the IP/IPv6 packet embedded in an ICMP/ICMPv6
   payload.  This advice is in line with the recommendations in BCP38.





Please note that it may take a couple of minutes from the time of submission
until the htmlized version and diff are available at tools.ietf.org.
