The following comment by Pasi Eronen against -03 version of the draft (and a proposed alternate text – thanks Pasi):

 

=====================================================

The text in Section 10.1.1.1 is pretty good, but it still doesn't mention the vulnerabilities that arise if you try to do zero configuration.

Perhaps something like this?

 

"It should be noted that authorization and zero configuration are not fully compatible. Even if the WTPs and the ACs are shipped with manufacturer-provided certificates, the WTPs need to know who the correct AC is in this deployment (as opposed to other ACs from the same vendor, purchased and controlled by an adversary), and the AC needs to know which WTPs are part of this deployment (as opposed to WTPs purchased and controlled by an adversary).

 

The threat analysis in this document assumes that WTPs can identify the correct AC, and the AC can identify the correct WTPs. Analysis of situations where either of these assumptions is not true is beyond the scope of this document."

=====================================================

 

has been addressed in -04. This is a one-week WGLC call for this change in -04 version of the threat analysis draft.

 

If you have any comments on this response do post them before September 19, 2008.

 

Thanks,

-mani
