Context-based confidentiality analysis: Context-based confidentiality analysisin dynamic Industry 4.0 scenarios - Tapa blanda

Sinopsis

In Industry 4.0 environments highly dynamic and flexible access control strategies are needed. The confidentiality analysis of the Trust 4.0 framework tries to solve the problem of analysing the security properties of a system using a context-based approach. Thus, there is a security model named “context metamodel”. Another important problem is that the transformation of an instance of a security model to a wide-spread access control standard is often not possible. This is also the case for the context metamodel. That is why, this book considers the transformation to the XACML standard. Moreover, another transformation which is very interesting to consider is one to an ensemble based component system which is also presented in the Trust 4.0 project. This book introduces an extension to the beforementioned context metamodel in order to add more extensibility to it. Furthermore, the thesis deals with the creation of a concept and an implementation of the transformations mentioned above. The thesis also contains an evaluation of the presented extensions to the metamodel and an evaluation of the transformations.
