XACML is the standard for attribute-based & policy-based access control and fine-grained authorization.
At the Cloud Identity Summit 2013, CIS Napa, last week, I had the privilege to be part of one of the sessions Hans Zandbelt was leading on advanced identity concepts. I chose to dive deeper into XACML and to provide updates for the developer community.
My slides are available from slideshare and below. Learn how developers can benefit from XACML.
