Offline Expansion of XACML Policies
In the last few years XML-based access control languages like XACML have been increasingly used for specifying complex policies regulating access to network resources. Today, growing interest in Semantic-Web style metadata for describing resources and users is stimulating research on how to express access control policies based on advanced descriptions rather than on single attributes. In this ...
متن کاملFormal analysis of XACML policies using SMT
The eXtensible Access Control Markup Language (XACML) has attracted significant attention from both industry and academia, and has become the de facto standard for the specification of access control policies. However, its XML-based verbose syntax and rich set of constructs make the authoring of XACML policies difficult and error-prone. Several automated tools have been proposed to analyze XACM...
متن کاملAnalysis of XACML Policies with SMT
The eXtensible Access Control Markup Language (XACML) is an extensible and flexible XML language for the specification of access control policies. However, the richness and flexibility of the language (along with the verbose syntax of XML) come with a price: errors are easy to make and difficult to detect when policies grow in size. If these errors are not detected and rectified, they can resul...
متن کاملXACML Policies for Exclusive Resource Usage
The extensible access control markup language (XACML) is the standard access control policy specification language of the World Wide Web. XACML does not provide exclusive accesses to globally resources. We do so by enhancing the policy execution framework with locks.
متن کاملLogic-based Conflict Detection for Distributed Policies
Policies are used to describe rules that are employed to modify (often distributed) system behaviour at runtime. Typically policies are created by many different people and there are many policies leading naturally to inconsistency between the policies, a problem that has been recognised and termed policy conflict. We present a novel formal semantics for distributed policies expressed in the AP...
