Soft Actor Critic (SAC) based Automatic Policy Generation and Effective Framework for Dynamic Trust Management for Securing SDN

Abstract

Abstract The Software Define Network (SDN) integrated with Internet of Things (IoT) reduces the scalability of IoT devices by managing the network, however the SDN are easily vulnerable to attacks as they used centralized controller for managing the network which can be easily manipulate by the attackers. The existing approaches focused on secure access control to the SDN controller but limits with controller scalability and trust management. By leveraging the problems in existing works, we propose SDMAC-Secure DynaMic Access Control framework which improves the security and provide efficient services to entities. Initially, all the users and applications are registered with attributes based on the registration, the authentication is performed to ensure the legitimacy. The policies are generated for the legitimate users by using Soft Actor Critic (SAC) which considers attributes, actions permitted, and temporal features to enhance network security, the conflicts between the policies are reduced by validating and storing the policies to database by the administrator. The proposed work is validated using iFog Sim tool and the performance comparisons between proposed and existing works are validated with several metrics. The simulation result shows that the proposed model work outperforms better than existing works.
