Semantics-based approach for detecting flaws, conflicts and redundancies in XACML policies ?
We provide policy analysis scheme to detect access contradictions among web services. We propose semantic-based policy analysis through deductive logic and inference rules. We present flaw, conflict and redundancy detection algorithms for XACML policy analysis. We show through experiments that SBA-XACML provides efficient detection mechanisms.
