Protocol gut check. That's how someone recently described some research I've got under way for a report we're calling the "TechRadar™ for Security Pros: Zero Trust Identity Standards," wherein we'll assess the business value-add of more than a dozen identity-related standards and open protocols. But it's also a great name for an episode of angst that recently hit the IAM blogging world, beginning with Eran Hammer's public declaration that OAuth 2.0 -- for which he served as a spec editor -- is "bad."
As you might imagine, our TechRadar examination will include OAuth; I take a lot of inquiries and briefings in which it figures prominently, and I've been bullish on it for a long time. In this post, I'd like to share some thoughts on this episode with respect to OAuth 2.0's value to security and risk pros. As always, if you have further thoughts, please share them with me in the comments or on Twitter.
Back in July, I wrote about a new RESTful API that cloud providers and provisioning vendors are working on for doing identity provisioning and synching: Simple Cloud Identity Management, or SCIM (like the milk). At last week's Internet Identity Workshop -- only five months after this draft spec made its formal debut! -- I had a chance to see the SCIM developers' live interop session in action. The interop saw successful participation by the likes of Cisco, Ping Identity, Sailpoint, salesforce.com, Technology Nexus, and UnboundID, with user accounts being securely created and torn down rapid-fire over the ether.
What's more, in talking with a more traditional on-premises identity vendor later in the week, I discovered that they loved how SCIM was shaping up, and planned to check it out ASAP as a way they could expose their own provisioning functionality.
In this Zero Trust world, with perimeters melting all over the place, I'm seeing signs that this lightweight API trend for IdM functionality is only going to accelerate. What do you think? If you're coming to Forrester Security Forum in a couple of weeks, I hope you'll grab me for a conversation about how this trend impacts your plans.
