The IESG has approved the following document: - 'Remote Triggered Black Hole filtering with uRPF ' <draft-ietf-opsec-blackhole-urpf-04.txt> as an Informational RFC
This document is the product of the Operational Security Capabilities for IP Network Infrastructure Working Group. The IESG contact persons are Ron Bonica and Dan Romascanu. A URL of this Internet-Draft is: http://www.ietf.org/internet-drafts/draft-ietf-opsec-blackhole-urpf-04.txt Document Announcement Write-Up for draft-ietf-opsec-blackhole-urpf currently in draft 04 having completed WG last call and AD Evaluation. Technical Summary Remote Triggered Black Hole (RTBH) filtering is a popular and effective technique for the mitigation of denial-of-service attacks. This document expands upon destination-based RTBH filtering by outlining a method to enable filtering by source address as well. Working Group Summary The WG last call period for draft-ietf-opsec-blackhole-urpf-03 was completed without opposition. Commentary on the draft in the current and prior revision at IETF 74 and before would indicate that the WG believes that the document is in suitable form to advance. AD Review revealed insufficient warning on the implications of using strict RPF. 04 revision is believed to satisfy both AD concerns and WG participants. Document Quality As it documents existing current practice both in router implementation and in operational practice and expands upon but does not obsolete rfc 3882 we believe that it is suitable to advance towards the goal of BCP status. Personnel Review by both industry peers (NANOG security BOF), and one of the originators of the method (Barry Greene) was solicited, and their input is noted in the contributions section. Joel Jaeggli Shepherded this document through the working group process. AD review was provide by R. Bonica. _______________________________________________ IETF-Announce mailing list [email protected] https://www.ietf.org/mailman/listinfo/ietf-announce
