XACML eXtensible Access Control Markup Language XML World September San Francisco, CA Simon Y. Blackwell Chairperson, XACML Technical Committee OASIS CTO, Psoom, Inc.

Simon Y. Blackwell, CTO XACML An XML specification for the expression of access control policies that can: –Be applied to anything referenced from XML –Refer to the content of the target of control –Be based on request context variables

Simon Y. Blackwell, CTO XACML Participants Authentify CrossLogic Entitlenet Entrust HP IBM Jamcracker Netegrity Oblix Psoom Reuters Tivoli University of Milan Verisign

Simon Y. Blackwell, CTO Cross Committee Representation SAML ebXML

Simon Y. Blackwell, CTO Why XACML? Promote Interoperability Ensure Uniformity Ease Development Control XML Fragments

Simon Y. Blackwell, CTO Promote Interoperability Multiple vendor security solutions in one enterprise Shared policy in business partnerships

Simon Y. Blackwell, CTO Ensure Uniformity Distributed, heterogeneous security systems with inconsistent policy –Multiple data base vendors –Custom applications –Firewalls –Operating systems

Simon Y. Blackwell, CTO Ease Development Separate policy from applications Standard means for policy to refer to the content of its target and the context of a request

Simon Y. Blackwell, CTO Control XML Fragments XML documents are frequently used to store information with different security needs –Health records –Contracts

Simon Y. Blackwell, CTO Features Layered architecture, e.g. –Users -> Groups -> Roles –Targets -> Target Security Levels –Standard Rights -> User Defined Rights XPATH Provisional Actions
