The IESG has approved the following document: - 'A Security Threat Analysis for Routing Protocol for Low-power and lossy networks (RPL)' (draft-ietf-roll-security-threats-11.txt) as Informational RFC This document is the product of the Routing Over Low power and Lossy networks Working Group. The IESG contact persons are Adrian Farrel and Alia Atlas. A URL of this Internet Draft is: http://datatracker.ietf.org/doc/draft-ietf-roll-security-threats/ Technical Summary This document presents a security threat analysis for the Routing Protocol for Low-power and lossy networks (RPL, ROLL). The development builds upon previous work on routing security and adapts the assessments to the issues and constraints specific to low-power and lossy networks. A systematic approach is used in defining and evaluating the security threats. Applicable countermeasures are application specific and are addressed in relevant applicability statements. Working Group Summary: This document is based upon draft-ietf-roll-security-framework that stumbled during IESG review. It was agreed that the resolution of the IESG issues was to produce a new document in line with the ROLL WG work item: > Sep 2012: Submit first draft of RPL threat analysis to the IESG to be > considered as an Informational RFC The goal of this document is to outline threats with the expectation that applicability statements will have to cover (i.e. mitigate or solve) these threats in some way. Document Quality: The previous document (draft-ietf-roll-security-framework) on which this document is based has had thorough reviews by Rene Struik, JP Vasseur, Michael Richardson and Adrian Farrel, which ultimately contributed to the re-submission of this document. This document has had review from Stephen Kent and Sean Turner.
