Abstract

Standard SQL is insufficiently expressive for representing many access control policies that are needed in practice. Nevertheless, we show how rich forms of access control policies can be defined within SQL when small amounts of contextual information are available to query evaluators. Rather than the standard, relational structure perspective that has been adopted for fine-grained access control, we consider instead the representation of dynamic fine-grained access control (DFMAC) policy requirements at the access policy level. We also show how DFMAC policies may be represented in SQL and we give some performance results for an implementation of our approach.Full Text at Springer, may require registration or fee
