Next Generation Access Control (NGAC)

Next Generation Access Control (NGAC)

  • Standard for Attribute-based access control (ABAC)
  • Alternate to XACML

XACML vs NGAC (Similarities)

  • Both standards are different approaches to ABAC
  • Both XACML and NGAC achieve separation of access control functionality of data services from proprietary operating environments, but to different degrees
  • Both offers fine-grained authorization policy creation and management
