How a Federated ID Hub Helps You Secure Your Data and Better Serve Your Customers

Welcome back to my series on bringing identity back to IAM. Today we’re going to take a brief look at what we’ve covered so far, then surf the future of our industry, as we move beyond access to the world of relationships, where “identity management” will help us not only secure but also know our users better—and meet their needs with context-driven services.

We began by looking at how the wave of cloud services adoption is leading to a push for federation—using SAML or OpenID Connect as the technology for delivering cloud SSO. But as I stressed in this post, for most medium-to large-enterprises, deploying SAML will require more than just federating access. By federating and delegating the authentication from the cloud provider to the enterprise, your organization must act as an Identity provider (IdP)—and that’s a formidable challenge for many companies dealing with a diverse array of distributed identity stores, from AD and legacy LDAP to SQL and web services.

It’s becoming clear that you must federate your identity layer, as well. Handling all these cloud service authentication requests in a heterogeneous and distributed environment means you’ll have to invest some effort into aggregating identities and rationalizing your identity infrastructure. Now you could always create some point solution for a narrow set of sources, building what our old friend Mark Diodati called an “identity bridge.” But how many how of these ad hoc bridges can you build without a systematic approach to federating your identity? Do you really want to add yet another brittle layer to an already fragmented identity infrastructure, simply for the sake of expediency? Or do you want to seriously rationalize your infrastructure instead, making it more fluid and less fragile? If so, think hub instead of bridge.

Beyond the Identity Bridge: A Federated Identity Hub for SSO and Authorization

This identity hub gives you a federated identity system where identity is normalized—and your existing infrastructure is respected. Such a system offers the efficiency of a “logical center” without the drawbacks of inflexible modeling and centralization that we saw with, say, the metadirectory. In my last post, we looked at how the normalization process requires require some form of identity correlation that can link global IDs to local IDs, tying everything together without having to modify existing identifiers in each source. Such a hub is key for SSO, authorization, and attribute provisioning. But that’s not all the hub gives you—it’s also way to get and stay ahead of the curve, evolving your identity to meet new challenges and opportunities.

The Future’s Built In: The Hub as Application Integration Point and Much More

Another huge advantage of federating your identity? Now that you can tie back the global ID to all those local representations, the hub can act as a key integration point for all your applications. Knowing who’s who across different applications allows you to bring together all the specific aspects of a person that have been collected by those applications. So while it begins as a tool for authentication, the hub can also aggregate attributes about a given person or entity from across applications. So yes, the first win beyond authentication is also in the security space: those rich attributes are key for fine-grained authorization. But security is not our only goal. I would contend that this federated identity system is also your master identity table—yes, read CDI and MDM—which is essential for application integration. And if you follow this track to its logical conclusion, you will move toward the promised land of context-aware applications and semantic representations. I’ve covered this topic extensively, so rather than repeat myself, I will point you to this series of posts I did last spring—think of it as Michel’s Little Red Book on Context… 😉

So the way we see it here at Radiant, the emergence of the hub puts you on the path toward better data management and down the road to the shining Eldorado of semantic integration, where your structured and unstructured data comes together to serve you better. But you don’t have to wait for that great day to realize a return—your investment starts to pay off right away as you secure your devices and cloud services.
