Instigating Again – XACML 3.0 Interop
One of the points I made during my vendor lightning round session at Burton Catalyst last week was that the industry should be looking ahead to an XACML 3.0 interop in 2011, perhaps at the next Catalyst conference. Catalyst was the site of the first ever XACML interop demonstration back in 2007 and would be a great venue again next year. It is expected that more vendors will adopt version 3.0 once OASIS completes formal standardization (currently a committee draft and will shortly be voted on as committee standard).
There are some basic usage scenarios that can be tested, such as implementing policies authored in one vendors PAP in another vendor’s PDP. Another scenario that is frequently mentioned is integrating a PDP with other vendor’s PEPs. What scenarios are most important to you?
Another item to consider is whether the industry needs certified conformance testing of XACML products. This capability has been very valuable to the federation market, but there is a lot of ambiguity today for externalized authorization manager products. If vendor products were certified as conformant by independent party, would that be valuable to you?
Finally, interoperability and standards conformance are more important than ever for the externalized authorization manager market. Demand is increasing from enterprises, SaaS vendors, cloud service providers, and others. These prospective implementers of XACML-based solutions must be confident of the functionality supported in commercial products and they should have a clear understanding of interoperability capabilities. That is why we are calling on other XACML vendors to join us in planning for the next interop event and also to seriously consider sponsoring a certification process.
