  1. Trygve Aspelien VTC 22.02.2007 SHIB & gJAF

  2. gJAF Overview • Provided as org.glite.security.authz Java package • Called from applications or web services via interceptor • SOAP/Axis or application specific • Presumably orthogonal to application and easy integrated • Contains a configured chain of PIP and PDP modules • PIP collects/extracts information to be sent to PDP • Each PDP evaluates its relevant attributes against its own Policy • Chain is configured to apply PDP decisions combination • Problems • Requires application specific manual chain configuration/programming • Unchanged but GT4-AuthZ has evolved

  3. Observations – AuthZ in EGEE/LCG • Wide diversity between sites • Typically based on LCAS/LCMAPS (C-based) • Foundation for gLite Java AuthZ Framework • DJRA3.1 (updated in DJRA3.3) – EGEE Security Architecture • Developer’s guide - https://edms.cern.ch/document/501718 • gJAF was developed to be compatible with Globus AuthZ framework • Version 1.0 released end 2004, some extensions later • Supports VOMS attributes (VOMS PDP), GridMapFile, BlackList • Now GT4-AuthZ significantly developed • More flexible configuration and better user creds handling

  4. gJAF interface • input: • subject (java.security) • operation (java xml qname) • message context (javax.rpc / axis) • PDP extract information through PIP -> PDP compares to a policy and make a decision. • How to do this with Shibboleth attributes?
