[ogsa-wg] Questions on OGSA WSRF Basic Profile 1.0

[Mark McKeown]

Hi folks,
         Sorry if these are dumb questions...

         I was looking through WSRF Basic Profile 1.0,
(Revised: Friday, June 10, 2005).

> Section 9.1.1 Mandated Secure Transport

"All messages are subject to interference and corruption during
transmission. The Profile mandates secure transmission of
messages."

Is there a reference that makes this case?

I have looked at the WS-I document "Security Challenges, Threats
and Countermeasures"
http://www.ws-i.org/Profiles/BasicSecurity/SecurityChallenges-1.0.pdf
which indicates that message level security is OK for many threats.


WSRF & ACID

Section 7 of Web Service Resource Properties 1.2 discusses
ACID and WSRF - a WSRF implementor can choose a concurrency
policy with regard to updating and retrieving resource properties,
so two implementations of a WS-Resource with the same operations
and PropertiesDocument could actually have different behaviour
leading to interoperability issues for clients - is this any area
for a WSRF profile to address?

thanks
Mark
