Furthermore, it integrates a webservice to an external user directory for local user import and remote user authentication.
  • Additionally, a Java library "Mapper Broker" has to be designed and implemented which supports the plug-and-play of backend services and the exchange of management, data, and push notifications via Kafka Broker.
  • Introduction of Attribute Based Access Control (ABAC/XACML)
