Title: On-line tracing of XACML-based policy coverage criteria,
Abstract: Currently, eXtensible Access Control Markup Language (XACML) has becoming the
standard for implementing access control policies and consequently more
attention is dedicated to testing the correctness of XACML policies. In
particular, coverage measures can be adopted for assessing test strategy
effectiveness in exercising the policy elements. This study introduces a set of
XACML coverage criteria and describes the access control infrastructure, based
on a monitor engine, enabling the coverage criterion selection and the on-line
tracing of the testing activity. Examples of infrastructure usage and of
assessment of different test strategies are provided.
