  1. Firewall Issues Research Group Chairs: Inder Monga, Leon Gommans

  2. FI-RG Goals • Study barriers and propose solutions to inter-organization grid deployment due to mid-boxes managed by varied administrative domains • Firewalls • NATs • VPN gateways • Application-level gateways … • Collect use-cases, classify issues, existing and new solutions, gap-analysis, research... Enthuse standards, explore grid-friendly solutions and influence vendor implementations 2

  3. Group Progress vs Charter • An inventory of the type of issues when Grid jobs have to deal with middle-box functions, application level gateways, VPN style gateways, etc. Describe and classify the issues in document #1 • Published as GFD-I.083 • An evaluation of existing middle-box (signaling-) protocols and functions. Recognize possible limitations and produce a list of requirements • What is the deployment story? Reasons why these are not well deployed • Formal document not started, presentation last OGF • An evaluation of approaches and solutions such as application level gateways, host based firewalls, VPN style gateways etc. Capture results in document #3 • Intent is to apply solutions to use-cases and do a “gap-analysis” 3

  4. Document Relationships Vendor Community Existing Solutions Description & Analyses Grid community Grid Firewall Issues & Analyses Documents 2&3 Emerging New Solutions Description & Analyses  Document #1 Vendor Community Research & Vendor Community 4

  5. Modified Group Milestones • GGF13: Charter discussion and group volunteers (done). • GGF14: Collection of existing documents with Group discussions (done) • GGF15: First draft of document #1 and Group discussions. (done) • GGF 16: RG-last call and submission of document #1. • GGF 17: RG last-call for use-cases document. Discussion on solutions document. (done) • GGF 18: Submit use-case document for public comment. Form and initiate solutions draft team (done) • GGF 19: Use-cases document published. Continue discussions and contributions to solutions draft • GGF 20: First draft of solutions and requirements draft • GGF21: Finalize solutions for public comment, initiate gap analysis and standardization opportunities • GGF 22: Publish solutions drafts, Gap analysis between standards and solution requirements • GGF 23: Publish gap analysis and start standardization activity (in OGF or other) 5

  6. Current recognition • Grid applications, its administrators and its user groups have to deal with security services not under their direct control (ex. The Firewall) • Multiple solutions are proposed and implemented in research community, which provides dynamic firewall brokering such as: • CODO - Cooperative On-Demand Opening (UoW/ANL) • Dyna-fire - Port knocking (U at Buffalo) • Token mechanisms for Optical connections (UvA) • See FI-RG Wiki pages for more details • Will firewalls move to one implementation model even if standardized? • At least not in the next 3 years 6

  7. New Approach • Separate firewall requirements from firewall control mechanisms, ie make the firewall simple and put complexity outside. • Abstract the dynamic nature and security considerations into service access methods using either a provisioning approach or signaling approach. 7
