  1. Gridshell Security Master Project Akylbek Zhumabayev Rochester Institute of Technology

  2. Agenda • Problem Statement • Approach to solution • Grid and Gridshell • Web Service • Security • Standards • Solution

  3. Problem Statement Security solution for gridshell: • Easy setup and configuration of client • Integrated with grid systems • Supports all security dimensions • Can be applied to popular web platform • Scalable: nodes, layers • Optimized for better performance • Reliable: message delivery, QoS

  4. Approach to Solution • Solution – specification for developers • Examples of implementation • Based on technologies considered secure • Designed on open security standards • Web Services – solution platform • Combination of transport and message security

  5. Grid • HPC nodes • Middleware HPC HPC Server HPC Client Client

  6. Gridshell • Teragrid • Simple API • Features Client Client Gridshell Web Service Grid 1 Grid 3 Grid 2

  7. Web Service (WS) • Proved platform for distributed systems • Popular XML-based web technology WS Client SOAP Message Transport Layer

  8. Security Access Control Trust Delegation • Cryptography • Security Context Message security context Message security context WS Client Grid SOAP Transport security context Transport security context

  9. Security Standards for WS Secure Context WS-SecureConversation (IBM) Reliability WS-Reliability (OASIS) WS-Reliable Messaging (OASIS) Trust WS-Trust (OASIS) XKMS (W3C) WS-Federation (IBM) IDFF Shibboleth Policy WS-Policy (W3C) WS-Security Policy (OASIS) Resource XACML (OASIS) RBAC (NIST) EPAL (IBM) SOAP WS-Security (OASIS) WS-Addressing (W3C) U/P SAML X.509 Kerberos REL XML XML Encryption (W3C) XML Signature (W3C)

  10. Popular WS Solutions • Microsoft WCF • Sun Metro • Apache Axis2 • Apache CXF • IBM WebSphere • BEA WebLogic • WSO2 WSF

  11. WS-* Stack Secure Context WS-SecureConversation (1,2,3) Reliability WS-Reliability (2) WS-Reliable Messaging Trust WS-Trust (1,2,3) XKMS WS-Federation IDFF Shibboleth Policy WS-Policy (1,2,4) WS-Security Policy (1,2) Resource XACML RBAC EPAL SOAP WS-Security WS-Addressing U/P SAML X.509 Kerberos (1,2) REL XML XML Encryption XML Signature Implemented in all solutions Partially implemented Not implemented

  12. GSI • Grid Community did much in security field • Security standard for grid systems • Supports some open security standards

  13. Solution • Common specifications • Platform-dependent specifications • Gridshell modules • Security dimensions • Performance • Client security infrastructure • Third-party products

  14. Examples • Microsoft WCF • Sun Metro + Apache
