Semantic role-based access control
… this thesis we propose two semantic ontological role-based access control (RBAC) reasoning processes. These processes infer user authorisations according to a set of role permission and denial assignments, together with user role assignments. The first process, SO-RBAC (Semantic Ontological …

Model-Based Analysis of Role-Based Access Control
… been made to give security, and in particular access control, a more prominent place in MDE, but most of these approaches require advanced knowledge in security, programming (often declarative), or both, making them difficult to use by less technically trained stakeholders. In this thesis, we …

Secure Access to Service-based Collaborative Workflow Across Organisations
… Computing, service-oriented architecture and role-based access control. Grid Computing has been developed to provide middleware for collaborative access to distributed processing services and distributed data sources, supporting distributed users that form Virtual Organisations. Some …

Insider threat simulation and performance analysis of insider detection algorithms with role based models
… which can simulate the insiders and generate access information in the form of logs. Currently there are many methods which use data mining algorithms to detect insider attacks. Role based detection is a well known mechanism to accurately distinguish insider behavior from the normal behavior. …

Categorization of Security Design Patterns
… a two-level characterization of system security based on work by Chung et. al., to elicit precise requirements. Part 2 uses a novel framework for relating this characterization to previously published strategies, or patterns, for secure software development. Included case studies suggest the …

An Access Control Model for NoSQL Databases
… concern. This research presents a context based abstract model by extending traditional role based access control for access control in NoSQL databases. The said model evaluates and executes security policies which contain versatile access conditions against the dynamic nature of data. The …

Agentic AI systems in professional domains: A probabilistic framework for role suitability and legal accountability
… and enterprise domains, with a focus on role suitability, orchestration maturity, and legal accountability. It introduces the Bounded Agentic Suitability Envelope, a dual-bound scoring framework that evaluates deployment viability using weighted assessments of agent capability and …

Distributed RBAC for subscription-based remote network services
… management inherent in distributed subscription-based resource sharing are investigated in this thesis. The thesis introduces a concept of authentication delegation and distributed RBAC (DRBAC) to support fine granular access control across multiple autonomous resource sites and subscribing …

Model driven security from UML models to access control architectures
… a security modeling language for formalizing <br>access control requirements. From models in these languages, we automatically <br>generate access control architectures for distributed applications. The <br>modeling languages and generation process are semantically well-founded and <br>are based …

Dynamic Role Lease Authorization Protocol for a Distributed Computing System
… potentially very large) in a Grid. Therefore, an access control mechanism that provides users appropriate access to the resources in a dynamic environment is required. Role Based Access Control (RBAC) models have been demonstrated to be an effective and efficient approach for an administrator to …

Digital Vehicle Inspection
… replace paper inspection checklists with a web-based system where vehicle inspections can be completed, stored, reviewed, and traced digitally. The system has two main parts. The mobile interface is used by inspectors while they are working around a vehicle. They can open an inspection, go …

Towards Collaborative Scientific Workflow Management System
… monitoring, seamless integration and access control of the workflow components among collaborators and so on. In this thesis, we propose a locking scheme to facilitate consistency management in collaborative SWfMSs. The proposed method works by locking workflow components at a granular …

Privacy, Access Control, and Integrity for Large Graph Databases
… guard against information breaches. In addition, access control mechanisms can be used to allow controlled sharing of data. Provision of privacy-protection, access control, and data integrity for graph data require a holistic approach for data management and secure query processing. This thesis …

Efficient Automated Security Analysis of Complex Authorization Policies
Access Control is becoming increasingly important for today's ubiquitous systems. Sophisticated security requirements need to be ensured by authorization policies for increasingly complex and large applications. As a consequence, designers need to understand such policies and ensure that they meet …

Privacy Preserving Enforcement of Sensitive Policies in Outsourced and Distributed Environments
… is still an open challenge for policy-based systems. On the one hand, taking any appropriate security decision requires access to these policies. On the other hand, if such access is allowed in an untrusted environment then confidential information might be leaked by the policies. The …

Exploring Dynamic Constraint Enforcement and Efficiency in Access Control
… are enforced in various ways depending on the access control model and the application. Role based access control (RBAC) employs restrictions on the activation of roles and the exercise of permissions by individuals for enforcing the constraints. However, whether a constraint specification …
