A Model Checking Based Approach for Verification of Attribute-Based Access Control Policies in Cloud Infrastructures

Attribute-Based Access Control (ABAC) model is a perspective access control model for cloud infrastructures used for automation of industrial, transport and energy systems as they include large number of users, resources and dynamical changed permissions. The paper considers the features of ABAC model and the theoretical background for verification of the ABAC policies based on the model checking. The possibility of applying the model checking is justified on the example of the ABAC policy. Implementation of the proposed approach was made using the UPPAAL verification tool. Experimental assessment shows high acceptability of the model checking not only for finding anomalies in ABAC policies but for finding decisions to eliminate them.
