[Pgi-wg] Teleconference tomorrow, March 13th - Security

[m.riedel at fz-juelich.de]

Thanks for your comments Etienne,

 just note that the reference model was my input to the group - the group itself may create a larger PGI ecosystem. People at OGF have been worried calling it referenc model, so in PGI we take ecosystem instead... :-)

Take care,
Morris

Morris,

Concerning PGI, I completely agree with you :

Even if the original use case was focused on data staging,

SECURITY is the basis for everything.


Taking as input following presentations :

-  'PGI Reference Model' by yourself, in particular slides :
    - 18 'Security is orthogonal to layers,
    - 19 'Orthogonal Security: Plumbings',
    - 22 'Still work to do?'.

-  'Unicore : A European Grid Technology' by Shiraz MEMON, in particular 
slide 7 'Standards in Unicore 6'

-  'The NorduGrid/ARC perspective', in particular slides 21 and 22 
'Security capability: Wishlist'

-  'Conformance Targets for Simple PGI Communication' of GENESIS


Interoperability absolutely requires that :

1) Trust stores (for roots of trust) and Authz Repositories (like 
'gridmap' files) have exactly the same semantic content (even if syntax 
can differ), and are carefully distributed to all sites.

2) VOMS attributes specified inside X509 proxies and inside SAML 
assertions have the same semantics, in order to permit translation in 
both directions.

3) Restrictions/Constraints specified inside X509 proxies and inside 
SAML assertions have the same semantics, in order to permit translation 
in both directions.

4) Endpoints are specified in compliance with GLUE 2.


So, I suggest to use the presentation 'Conformance Targets for Simple 
PGI Communication' of GENESIS as the basis document for our work.


We have first to agree on at least the above points inside 1 or more 
Security Profiles (Semantic, Repositories, X509 syntax, SAML syntax).

Then we can successfully apply SECURITY and GLUE to improve JSDL, BES 
and Data transfer & management.


Meanwhile, I thank Johannes WATZL in advance for uploading the minutes 
of the PGI sessions  (in particular the remote speech by Duane MERRIL).

Besides, at OGF25, Joni HAHKALA of CERN (tel +41 22 76 76179) 
Joni.Hahkala at cern.ch explained to me that gLite proxy restriction 
attributes are developed by himself.


Best regards.
