The IP Security Maintenance and Extensions (ipsecme) working group in the Security Area of the IETF has been rechartered. For additional information please contact the Area Directors or the WG Chairs. IP Security Maintenance and Extensions (ipsecme) ------------------------------------------------ Current Status: Active Working Group Chairs: Paul Hoffman <paul.hoffman@vpnc.org> Yaron Sheffer <yaronf.ietf@gmail.com> Assigned Area Director: Sean Turner <turners@ieca.com> Mailing list Address: ipsec@ietf.org To Subscribe: https://www.ietf.org/mailman/listinfo/ipsec Archive: http://www.ietf.org/mail-archive/web/ipsec/ Charter of Working Group: The IPsec suite of protocols includes IKEv1 (RFC 2409 and associated RFCs), IKEv2 (RFC 5996), and the IPsec security architecture (RFC 4301). IPsec is widely deployed in VPN gateways, VPN remote access clients, and as a substrate for host-to-host, host-to-network, and network-to-network security. The IPsec Maintenance and Extensions Working Group continues the work of the earlier IPsec Working Group which was concluded in 2005. Its purpose is to maintain the IPsec standard and to facilitate discussion of clarifications, improvements, and extensions to IPsec, mostly to IKEv2. The working group also serves as a focus point for other IETF Working Groups who use IPsec in their own protocols. The current work items include: In an environment with many IPsec gateways and remote clients that share an established trust infrastructure (in a single administrative domain or across multiple domains), customers want to get on-demand point-to-point IPsec capability for efficiency. However, this cannot be feasibly accomplished only with today's IPsec and IKE due to problems with address lookup, reachability, policy configuration, and so on. The IPsecME Working Group will handle this large scale VPN problem by: * Creating a problem statement document including use cases, definitions and proper requirements for discovery and updates. This document would be solution-agnostic. * Publishing a common solution for the discovery and update problems that will satisfy the requirements in the problem statement document. The working group may standardize one of the vendor solutions, a combination, an superset of such a solution, or a new protocol. * Reviewing and helping publish Informational documents describing current vendor proprietary solutions. Recently discovered incorrect behavior of ISPs poses a challenge to IKE, whose UDP messages (especially #3 and #4) sometimes get fragmented at the IP level and then dropped by these ISPs. There is interest in solving this issue by allowing transport of IKE over TCP; this is currently implemented by some vendors. The group will standardize such a solution, using draft-nir-ipsecme-ike-tcp as a starting point. This charter will expire in August 2014 (24 months from approval). If the charter is not updated before that time, the WG will be closed and any remaining documents revert back to individual Internet-Drafts.
