Repairing Inconsistent XML Write-Access Control Policies
XML access control policies involving updates may contain security flaws, here called inconsistencies, in which a forbidden operation may be simulated by performing a sequence of allowed operations. This paper investigates the problem of deciding whether a policy is consistent, and if not, how its inconsistencies can be repaired. We consider policies expressed in terms of annotated DTDs definin...

The role-based access control (RBAC) model provides a flexible method for specifying such policies. Extending the RBAC model to include role parameterization addresses the problem of role proliferation which can occur in...
