1 NIST NwHIN Testbed
2 What's NwHIN The nationwide health information network is a set of standards, services and policies that enable secure health information exchange over the internet.
3 Purpose To provide testing tools for NwHIN Specifications.
4 Specifications Authorization Framework Production Specification V1.0 – SAML, CERTS Messaging Platform Production Specification V2.0 – SAML Patient Discovery Production Specification V1.0 – IHE_XCPD Query for Documents Production Specification V2.0 – IHE_XCA Retrieve Documents Production Specification V2.0 – IHE_XCA
5 Tool Support for Specs Make NIST tools available for testing Started with the 3 distinct tools XD* tools Pix/Pdq tool CDA Validator
6 Support for Specs Our tools worked at document and message level Tooling failed because of soap header requirements Lack of SAML support. Validated messages from Log files
7 Initial Approach to Improving theTools Add SAML to the IHE Pix/Pdq and XD* tools Keep them as separate tools. Some Problems Difficulty with maintaining tools in two locations. Need to modify some of the tools for gateway testing.
8 NIST XD* Tools Strengths Query Support Retrieve Support HTTP, SOAP support Weakness Missing SAML NIST IHE Pix/Pdq Tool Weakness Missing SAML, Fragile Soap Handler Strengths XCPD MessageType Support PRPA_IN201305UV02 PRPA_IN201306UV02 Tool Review
9 Current Approach Combine what we have into one testbed. Expanding the XD* tooling framework into a NHIN tooling testbed. Use What We Have Using the message validator from IHE Pix/Pdq tool. Take advantage of the XD* infrastructure
10 What's Done Now
11 Next area of focus is xcpd simulators
12 Find Patients Simulator
13 SAML Tool Tool being developed by a contractor, Metrix Technologies Message Validator with SAML option Simulator with SAML option.
14 SAML Tool Tool being developed by Contractor Matrix
15 SAML Validator Output
16 Initial Focus is Validation Insert assertion graphic as example of whats tested. Keep it focused
17 Rampart used in Simulators Rampart work is just starting. Rampart handles the digital signatures but the assertion Rules need to be done by hand.
18 Benefits For NIST Leverage what we have Reduce development time Better tool support Benefits For Users One place for security checks Unified look and feel XD* tool currently used by NwHIN
