Re: [802SEC] +++ SEC EMAIL BLLOT +++ MOTION: Authorize the Link Security Exec SG to become an 802.1 SG




Ken -

I think it is high time to inject a bit of reality into this discussion.

Firstly, it is not at all clear to me what you mean when you describe 802.1 
as a MAC-oriented working group. Our charter is 802's architecture, 
interworking, and higher (than MAC) layer issues. I would certainly agree 
that the link security activity should not be buried within one of the 
MAC-specific groups (.3, .11, ...etc.), but I see nothing about the 
existing charter of 802.1 that doesn't make it a good fit for us.

Secondly, you talk about 802.10 and its charter being the best fit for this 
activity. If 802.10 existed in any meaningful way right now, I would 
perhaps agree with you; however, as you have acknowledged, active 
participation by 802.10 members is a problem for them in these 
funding-challenged times, and they have been conspicuous by their absence 
at meetings of the link sec study group to date. Having said that, the 
meetings we have held do not seem to have suffered from a lack of security 
expertise - just not expertise that used to be in 802.10.

Thirdly, 802.1 is not without its own track record, however small, in 
developing security standards. In fact, it is arguably the case that 802.1 
is, to date, the only 802 working group that has developed a successful 
security standard for LANs; unlike the 802.10 standards, 802.1X has been 
implemented, and found to be useful, by a significant number of vendors. As 
a consequence, we now have participants in 802.1 that are there 
specifically to work on security issues; this is, in fact, one of the 
reasons that 802.1 made the offer to host the link sec SG, as these 
particular experts wanted to avoid the potential for conflicting meeting 
times if the two activities were kept separate.

A final point. Strictly speaking, as 802.10 is a hibernating group, the 
charter of 802.10 is restricted to exactly one thing right now; performing 
any maintenance that is required for the standards that they developed when 
they were an active WG. It has no charter with regard to any new work. That 
being the case, whatever new work comes out of this activity will, of 
necessity, result in the creation of a new charter, either by extending the 
charter of an existing (active) working group, or re-chartering hibernating 
group, or chartering a new working group altogether. When making that 
decision, it would make absolutely no sense to me to place the work within 
802 in a way that conflicts with existing non MAC-specific activity in the 
security area, all of which currently resides in 802.1.

Regards,
Tony
