PS to previous reply:
 
If the WSDL says that certain security is always applied then that will
happen even if the Choreography description does not mention it.  If the
Choreography description contains conflicting requirements that the
engine can not resolve then there will be an error.  If the WSDL allows
certain security as an option then whether it is actually applied or not
can depend on the Choreography description.  Also my previous message
was actually only about the requirements not about how those
requirements are met.  It may well be that we agree that certain
requirements on Choreography description abilities are met in other ways
than CDL features.

Hi Tony,
 
Assuming that our final CDL will be based on WSDL (which might be an
incorrect assumption, given the fact that we currently have no stable
spec), it's very likely that WSDL 2.0 will contain policy assertions
including security-related ones.
 
Would it still make sense, under that scenario, to replicate those
security policies at the CDL level?
 
Ugo

Dear Colleagues,
 
On the teleconference last night I kind of agreed to kick the ball into
play on drafting some security requirements.  So here goes.
 
It seems to me that the CDL can be declarative with regard to security.
In other words it should support notation for flagging that certain
security requirements have to be met at this point but can then rely on
the 'stack' below the Choreography language layer to 'make it so'.
 
It should be possible to flag that a certain policy applies from this
point in the choreography until the choreography ends or another flag is
encountered.
 
Should be able to refer out to standard policy sets or state specific
requirements explicitly.  These should include ability to require:
 
authentication of the partner and or the message content source
 
that a secure audit log is made
 
that a message is protected from change (integrity)
 
that the contents of a message are hidden (confidentiality)
 
that the sending of a message is non-repudiable
 
that the receipt of a message is non-repudiable
 
that the message or message exchange is protected against replay
 
that the time of sending of a message is recorded
 

that the time of receiving of a message is recorded
 
that a time (/date) stamp is attached to a message when sent.
 
I am sure I have missed various things, but I hope that will encourage
others to add / correct / rephrase.
 

Best Regards,

Tony
