Introduction to the security components used in FIWARE architecture. What is the standard communication of the oAuth2.0 standard. What about the fine grane access to the information using XACML standard. How to use JWT with FIWARE Secure components. What are the different types of accessing support are allowed. How to offer security access to your applications using these components. What is eIDAS and eID and how to integrate them in the FIWARE Security architecture. Finally an overview of the Data Usage Control using FIWARE Security components
