NGAC is a fundamental reworking of traditional access control into a form suited to the needs of the modern, distributed, interconnected enterprise. NGAC is based on a flexible infrastructure that can provide access control services for a number of different types of resources, accessed by a number of different types of applications and users.
In this joint talk with David Ferraiolo from NIST we introduced NGAC and did a live demo showing how it can be applied to augment traditional RBAC with high level concepts such as time and location in an efficient and scalable way.
