I wrote this last week, and passed it around for obvious objections. https://github.com/mcr/iotwg-charter/blob/master/iotwg-charter.md You can use the crayon/edit button on github to suggest changes, or email. Charter for Working Group The words "Internet of Things" or IoT have come to mean anything and everything to a wide group of technology players. The IETF has been working on a wide variety of protocols for use by machine to machine communication. This include CoAP, CBOR, 6TISCH, ROLL, SUIT, NETCONF SZTP, T2TRG, ANIMA's BRSKI onboarding protocol, and most recently RFC8520, the Manufacturer Usage Description. The IETF has tried to focus on categories of what limited things can do, and this has resulted in a number of useful documents from the Light-Weight Implementation Guide (LWIG). RFC7228 is a key product, having provided terminology and scaling understanding to the entire industry. All of this has been about scaling the Internet technologies to small devices and constrained networks. In aggregate, these devices on small networks present a significant operational risk to the Internet as a whole, and even to individual Enterprise, simply due to their numbers, and lack of opportunity for regular human supervision. IoT devices already exist today in vast numbers. Most devices that people are personally familiar with are in the BlueTooth Connected devices, or Web-Connected devices that use WiFi to reach servers on the Internet ("the Cloud"). Increasingly, the IETF view of machine to machine communications are colinizing new greenfield situations. The IETF notion of autonomous networks of devices is still a minority view compared to the market IoT industry of cloud-only connected devices, but the transition is occuring. RFC8520 was created to bridge the gap between devices wholly controlled by a local operator (such as Enterprise IT), and devices which can not assume any infrastructure at all, and must rely entirely on cloud communications for command and control. This working group concerns itself with Operational Security of IoT systems. This includes: * factory provisioning of devices * onboarding of devices * access control of devices to network resources * administrative control of devices * asset management of devices, as it pertains to software/firmware versions * isolation/quarantine of devices * remediation of broken devices * end of life management of devices The WG is chartered explicitely to work on MUD (RFC8520) and extensions to it. The WG is chartered to work on onboarding protocols, specifically including derivaties of BRSKI (RFC-tbd), but not limited to just that protocol. The WG is not expected to pick a winner, and is encouraged to work on a multitude of use-case specific protocols: better to get one use case right, than to be too-complex jack of all trades. The WG is expected to articulate clear applicability statements for each protocol. The WG is expected to produce concise Roadmap documents that explain how a variety of IETF (and other) protocols can work together to satisfy the Operational needs of specific IoT areas. These roadmap documents needn’t result in RFCs. Neither the WG nor the IETF has exclusivity here, and an ideal document would be one that the WG helps to start, but a specific industry alliance becomes the lead editor for. There will be coordination with many other WGs beyond the list above, and this WG may accept applicability statement work from other WGs about specific ways to deploy their protocols. The WG will operate through a series of virtual interim meetings. This is driven by a need to interact regularly with other industry grouops, and due to the variety of topics which will not always be able to get quorum as a committee of the whole. {unusual, maybe not charter appropriate, but rather saag-like} During in-person meetings, the WG will deal with typical status and document progress issues during one hour (or less) of the time, and during another hour, will be open to slideware presentations and tutorials on current IETF or other-SDO IoT efforts. The goal of these presentations is to quickly communicate current IoT systems state to the rest of the IETF. It is acknowledged that part of the value is in YouTube content, and some content should be done at IAB tech plenaries rather than at the WG. The initial set of work items is included below as milestones, which only require AD approval. Milestones * adopt the constrained-voucher/constrained-BRSKI work from ANIMA. * adopt the dtsecurity-zero-touch work from 6tisch, which can not finish before a LAKE finishes. * create a list of a series of MUD extensions, and revise this milestone * adopt a cloud-less (MASA-less, AAA-less) onboarding mechanism (possibly a version of EAP-NOOB), that can be used at the retail level. * negotiate with EMU WG on how to proceed with TEAP-BRSKI, and revise this milestone. * adopt a cloud-driven onboarding mechanism that can be used in completely offline situations without requiring renewals (perhaps revising RFC8366). ... -- Michael Richardson <mcr+IETF@sandelman.ca>, Sandelman Software Works -= IPv6 IoT consulting =-
