Microsoft announced during last week's RSA conference that it would not be shipping Windows CardSpace 2.0. A lot of design imperatives weighed on that one deliverable: security, privacy, usability, bridging the enterprise and consumer identity worlds – and being the standard-bearer of the "identity metasystem" and the "laws of identity" to boot. Something had to give. What are the implications for security and risk professionals?
The CardSpace model had nice phishing resistance properties that cloud-based identity selectors will find hard to replicate, alas. But without wide adoption on the open Web, that wasn't going to make a dent anyway. We'll have to look for other native-app solutions over time for that.
If you're a security and risk professional in charge of protecting consumer-facing applications, you may have heard that OpenID is a “toy,” or it's an insecure protocol, or other critiques. And then here comes the recent news by former early adopter 37signals to drop its OpenID login support, which has occasioned some soul-searching in the Web 2.0 identity community. Check out commentary from Scott Gilbertson of Wired's WebMonkey, Dare Obasanjo, and reaction from “social login” vendor JanRain
When OpenID appeared on the scene, more robust solutions based on SAML were well under way for many years and seeing adoption, but only in scenarios involving limited circles of trust — typically point-to-point enterprise outsourcing scenarios and specialized higher-education communities — rather than in broad-based consumer populations.
