Re: [IPsec] Proposed work item: WESP extensibility

2009-11-29 Thread Stephen Kent
I am opposed to pursing this work at this time. The ongoing discussion on the list suggests that the arguments put forth for WESP use in the OSPFv3 context, the first concrete proposal outside of the middlebox inspection context that motivated WESP, have not been validated. The presentation

2009-11-29 Thread Stephen Kent
I think that there has been insufficient discussion of whether those who wish to make use of IPsec to enforce mandatory access controls require the facilities described by the folks who have proposed this. At the WG meeting 2 weeks ago I made two observations: - possible use of CIPSO for c

Jack, Thanks for describing the additional selection criteria that must be employed to avoid the problem I cited. Given this more complete description of the selection criteria, I am not convinced that that is a significant benefit for using WESP in this context. - Whether using WESP or j

For someone, who spent quite a lot of time working in this area, it is not difficult fo figure out what is really important and what is not. But, I think, a newcomer could be confused by a long list of all possible numbers. This answer is inconsistent, and that's the crux of the issue I have w

[IPsec] Proposed work item: IKE/IPsec high availability and load sharing

2009-11-29 Thread Yaron Sheffer
This work item will define the problem statement and requirements for a solution that allows interoperable HA/LS device groups. Mixed-vendor clusters are specifically out of scope; but single-vendor clusters should be fully interoperable with other vendors' devices or clusters. The main challeng

[IPsec] Proposed work item: WESP extensibility

2009-11-29 Thread Yaron Sheffer
This draft proposes an extensibility framework for WESP, as well as several specific extensions. Proposed starting point: http://tools.ietf.org/id/draft-montenegro-ipsecme-wesp-extensions-00.txt. Please reply to the list: - If this proposal is accepted as a WG work item, are you committi

[IPsec] Proposed work item: Labelled IPsec

2009-11-29 Thread Yaron Sheffer
This work item proposes to extend IKEv2 (and IKEv1) so as to allow IPsec to be used in environments that require Mandatory Access Control. It is envisioned that this will be used by modern high-security operating systems, that go beyond the currently supported Multilevel Security (MLS). Propose

[IPsec] Proposed work item: Failure detection in IKEv2

2009-11-29 Thread Yaron Sheffer
This work item proposes an IKEv2 extension to allow an IKE peer to quickly and securely detect that its opposite peer has lost state. This is claimed to be quicker than the current method, which is based on time outs. Proposed starting point: http://tools.ietf.org/id/draft-nir-ike-qcd-05.txt or

[IPsec] Proposed work item: IKEv2 password authentication (SPSK)

2009-11-29 Thread Yaron Sheffer
This draft proposes a particular method for mutual authentication of IKEv2 peers using a short, low quality shared secret (a.k.a. "password"). The proposal is to embed this method in the IKE exchange, rather than use EAP. Proposed starting point: http://tools.ietf.org/id/draft-harkins-ipsecme-s

[IPsec] Proposed work item: Childless IKE SA

[IPsec] Proposed work item: EAP-only authentication in IKEv2

This draft proposes an IKEv2 extension to allow mutual EAP-based authentication in IKEv2, eliminating the need for one of the peers to present a certificate. This applies to a small number of key-generating EAP methods that allow mutual authentication.   Proposed starting point: http://tools.ie
