A principled approach to object deletion and garbage collection in multilevel secure object basesODBMSs). The guidelines are formally stated as security principles. We also show how to design a garbage collection mechanism in a multilevel secure ODBMS that ensures both security and referential integrity.

Compile-time Flow analysis of Transactions and Methods in Object-Oriented Databasesd policies for Methods and Inheritance. However, discretionary authorization models do not provide the high assurance required in systems where Information flow is considered a problem. Mandatory models can solve the problem but usually they are too rigid for commercial applications. Therefore discr

Capability-based primitives for access control in object-oriented systemsommon foundation for access control in object-oriented systems. This paper presents a primitive capability-based access control architecture that can model a variety of authorization policies. The architecture described is integrated at the meta-object level of the Meta-Object Operating System Envir

An execution model for multilevel secure workflowsctivities (or tasks) in a workflow, task dependencies are specified among them. In a multilevel secure (MLS) workflow, tasks may belong to different security levels. Ensuring the task dependencies from the tasks at higher security levels to those at lower security level (high-to-low dependencies) ma

Task-based authorization controls (TBAC): a family of models for active and enterprise-oriented auth access controls from a task-oriented perspective than the traditional subject-object one. Access mediation now involves authorizations at various points during the completion of tasks in accordance with some application logic. By taking a task-oriented view of access control and authorizations, TBA

Firstly, since the description of a workflow process explicitly states when which function is to be performed by . security specifications may be automatically derived from such descriptions. Secondly, the derived security specifications have to be enforced. This paper considers these

At the bottom tier, our scheme requires separate single-level indices, one for each partition of the multilevel relation; at the top tier, our scheme requires a . multilevel index consisting of only those key values from the single-level indices that
