EAR-ABAC: An Extended AR-ABAC Access Control Model for SDN-Integrated Cloud Computing

Due to the distinguished nature of cloud computing, it needs an effective access control model, that can cope with its broad net-work access, on-demand self-service, and so on. When thinking in integrating the Software-defined Networking (SDN) with the cloud computing environment, to let SDN serve, secure, and con-trol the cloud environment. The authors must think about a per-fect access control model to secure access to the SDN-integrated cloud environment. This paper proposes an extended access con-trol model for the SDN-integrated cloud computing. Where the author’s AR-ABAC access control model [15] is extended to suit the SDN-integrated cloud environment distinguished nature. The extended model can make the election process about the num-ber of attributes considered for making access decisions. In ad-dition it can perfectly deal with the SDN software controllers (OpenDaylight controller). Finally the model ensures secure re-source sharing among potential untrusted tenants and supports dif-ferent access permissions to the same user at the same session
