Abstract. We present a modelling language, called X-Policy, for webbased collaborative systems with dynamic access control policies. The access to resources in these systems depend...
—Managing access control policies is a complex task. We argue that much of the complexity is unnecessary and mostly due to historical reasons. There are number of legacy policy s...
Abstract. Managing access control policies in modern computer systems can be challenging and error-prone. Combining multiple disparate access policies can introduce unintended cons...
We present a formal, tool-supported approach to the design and maintenance of access control policies expressed in the eXtensible Access Control Markup Language (XACML). Our aim is...
Role-based access control has been a focal area for many security researchers over the last decade. There have been a large number of models, and many rich specification language...
