9. „Conclusions“ from Observation NASA NEX does not allow straight OpenID login! NASA NEX is accepting OpenID login, but only if your identity was checked by NASA before So essentially, NASA has applied their on extra security to lift OpenID identity assurance level 0 to their own level Problem: –You will end up in one NEX account for each of your OpenID accounts –Not interoperable if each „federation“ service provider uses on selection of OpenID providers 2012 (c) Secure Dimensions9NASA NEX & OpenID

10. This fits the SAML2 / OpenID proposal SAML 2 as the standard for exchanging user assertions and establishing identity assurance throught trusted Identity Providers Users from trusted IdPs are directly accepted Users from OpenId IdPs require extra checking Advantage of SAML2 base vs. NASA approach –Not each Service Provider must create accounts themselves – trusted Identity Providers would do that –Guarantee to the user that once accredited at the SAML2 / OpenID IdP, the account would work with all Service Providers and not only NEX from NASA 2012 (c) Secure Dimensions10NASA NEX & OpenID
