RE: Trying to summarise (was Re: DAP and security)

Hi Maciej, All,

The file under [1] is not clickable, therefore browsing the relationships between various identifiers may be difficult at the first time.
At [3,4] there is/are clickable versions of the BONDI API specs.
At [5] there are live updates of the APIs.

I hope this helps.

Thanks,
Marcin

Hi Maciej,

Thanks for your review!

The page <http://www.w3.org/2009/dap/> does not yet include the BONDI 1.1 Candidate Release at [1].
The device capabilities [2] could be regarded as a compact form of security considerations within BONDI APIs.
It should be noted that the device capabilities - although related to BONDI APIs - could be regarded as generic enough to incorporate any APIs.

Based on the BONDI policy format specification, I would propose to start with the following default policy for "the Web":

<policy-set combine="deny-overrides">
  <policy description="Default Policy for BONDI API & device capabilities within Win2K environment">

This is pretty much how I feel about the security design aspects of
many of the proposed DAP specifications. If you look at the specs
listed in the Input section here: <http://www.w3.org/2009/dap/>, they
mostly have missing or unhelpful Security Considerations sections. The
BONDI security document listed there doesn't seem to provide anything
for security other than a policy mechanism, with no hint of what might
be a safe default policy for the Web.

Apple will consider joining the DAP Working Group, but the security
direction so far is on reason we are hesitant.

Regards,
Maciej
