1. NASA Use Cases for Secure Service Oriented Architectures to Support GEOSS Karen Moe NASA Earth Science Technology Office CEOS WGISS-28 CSIR, Pretoria, South Africa 28 September 2009

2. WGISS-27 Security Recommendations What are GEOSS security needs for interoperability? Describe levels of security needs in user scenarios, capture in ‘white paper’ from WGISS-27 session –Sensor web pilots –Grid processing pilots –Portal pilots Facilitate working session with security experts within agencies to resolve way forward POC Michael Burnett

3. page 3 Motivation As SOA and web services are new – Pro-actively work with agency office responsible for cyber-security Enable web services in systems with firewall security mechanisms Determine nature of the end users and associated risks Bottom line: Protect assets – data, processors, sensors

4. page 4 NASA Activities for Secure SOA A collaboration between NASA’s Earth Science and Constellation programs was initiated in July 2009 Each program will independently assess needs for secure access to data and web services A joint session will seek common security drivers and identify program-unique drivers (if any) Results to be presented to NASA CIO this fall

5. page 5 SOA Security Needs - Approach A small Earth science team was established to address web service and sensor web security implications for –Science data operations –Data acquisition / sensor webs Team members will develop use cases to address “80%” of the needs (more typical cases to be captured) initially focusing on –Authentication –Authorization
