Improving the Self-adaptive Authorization Framework and solve its cold start problem using the concept of trust and I-sharing

Authorization systems are an important part of security systems that are responsible for protecting resources. With the increasing number of users in organizations, managing the authorization infrastructure has become increasingly time-consuming and error-prone and misconfiguration of policies has reduced the effectiveness of these systems. Researchers recommend dynamic access control methods as an effective way to issue licenses in these systems. Since the sources of decision making in these methods are the defined policies and user records, there are no special restrictions for new users and these methods face the problem of cold start. In this paper, to solve this limitation, the concepts of trust and I-sharing are used, and a new method for improving the Self-Aaptive Authorization Framework (SAAF) called ISAAF is presented. ISAAF is a framework for self-adaptive control of authorization systems using the MAPE-K autonomous reference model, which estimates the trust of new users using the trust of users with whom they have common features.
