Dynamic risk-based decision methods for access control systems
In traditional multi-level security systems, trust and risk values are pre-computed. Any change in these values requires manual intervention of an administrator. In many dynamic environments, however, these values should be auto-adaptive, and auto-tunable according to the usage history of the users. Moreover, occasional exceptions on resource needs, which are common in dynamic environments like...
متن کاملAttribute-based Access Control for Cloud-based Electronic Health Record (EHR) Systems
Electronic health record (EHR) system facilitates integrating patients' medical information and improves service productivity. However, user access to patient data in a privacy-preserving manner is still challenging problem. Many studies concerned with security and privacy in EHR systems. Rezaeibagha and Mu [1] have proposed a hybrid architecture for privacy-preserving accessing patient records...
متن کاملA context-sensitive dynamic role-based access control model for pervasive computing environments
Resources and services are accessible in pervasive computing environments from anywhere and at any time. Also, due to ever-changing nature of such environments, the identity of users is unknown. However, users must be able to access the required resources based on their contexts. These and other similar complexities necessitate dynamic and context-aware access control models for such environmen...
متن کاملModelling Dynamic Access Control Policies for Web-Based Collaborative Systems
We present a modelling language, called X-Policy , for web-based collaborative systems with dynamic access control policies. The access to resources in these systems depends on the state of the system and its configuration. The X-Policy language models systems as a set of actions. These actions can model system operations which are executed by users. The X-Policy language allows us to specify e...
متن کاملPrivacy Preserving Dynamic Access Control Model with Access Delegation for eHealth
eHealth is the concept of using the stored digital data to achieve clinical, educational, and administrative goals and meet the needs of patients, experts, and medical care providers. Expansion of the utilization of information technology and in particular, the Internet of Things (IoT) in eHealth, raises various challenges, where the most important one is security and access control. In this re...
