Abstract-Service-Oriented Architecture (SOA) and Web Services (WS) offer advanced flexibility and interoperability capabilities. However they imply significant performance overheads that need to be carefully considered. Supply Chain Management (SCM) and Traceability systems are an interesting domain for the use of WS technologies that are usually deemed to be too complex and unnecessary in practical applications, especially regarding security. This paper presents an externalized security architecture that uses the eXtensible Access Control Markup Language (XACML) authorization standard to enforce visibility restrictions on traceability data in a supply chain where multiple companies collaborate; the performance overheads are assessed by comparing 'raw' authorization implementations -Access Control Lists, Tokens, and RDF Assertions -with their XACML-equivalents.
REF showed the utilization of XACML authorization for the traceability of supply chain activities.
