Recertification in dynamic authorization systems

Access Governance tools are becoming standard in IAM infrastructures. However, they mainly focus on "static" access controls, e.g. the entitlements granted to a user based on roles and other paradigms. Recertification is supported by these tools, and the solutions are maturing quickly. Thus, that part of Access Governance is easy to solve.

However, the next wave is coming with the increasing success of tools which are commonly called Entitlement Servers or Policy Servers. I tend to call them Dynamic Authorization Systems because they authorize based on rule sets and attributes at runtime. While the rules are set, the attributes are changing. I'm a strong believer in these tools and in XACML als the underlying standard for communication between the different modules and in heterogeneous environments.

But: What about Access Governance for these environments? Some of the Access Governance tools support that to some degree, allowing to pre-evaluate some business rules which use defined roles or attributes. However, many rules - especially business rules like "users of the life insurance backoffice with the role xxx and the defined constraint for signing payments up to 50,000 € are allowed to sign that type of claim" are out of scope. There is some support for testing such rules for example provided by Axiomatics.

However, I don't see a solution which provides integrated Access Governance for all types of entitlements. Given that Dynamic Authorization Systems gain momentum, its just a matter of time until auditors will ask for such solutions. These solutions should, like modern Access Governance tools, support the lifecycle management for the policies including approvals, auditing and analysis, and the recertification of such rules. That is more complex than what is done today. But, without any doubt, we will need this soon.

It will be interesting to observe who becomes the leader in that market. The vendors in the market of Dynamic Authorization Systems themselves? The Access Governance vendors? New startups?

By the way: The topic isn't that new - look here.
