  1. Dataplane and Content Security on Optical Networkspanel

  2. Agenda Digital Media Security - Laurin Herr Data Encryption - Kim Roberts Firewall Issues - Leon Gommans Discussion.

  3. Firewall Issuesand the Grid Leon Gommans - University of Amsterdam

  4. Perspective “It would be good if grandma went to a retirement home“

  5. Perspective “It is a good thing that we have firewalls “

  6. Prevention: both good and bad Grid Application Issues Prevent Firewall Network safety! My application needs to work! Network Security Issues Act Detect Network Security Cycle

  7. Firewall Issues Research Group • Research Group at the Global Grid Forum (www.ggf.org) • Scope: Issues with firewall style functions • Functional, Control, Performance, Organizational issues • Firewalls & NATs, VPN gateways, Application gateways • First formal meeting held at june GGF meeting in Chicago. • Looking for additional participation from applications

  8. Charter items • Collect and document issues from the grid viewpoint. • Define the categories of issues. • Study existing technologies available • Identify gaps and define requirements for standards bodies. • Issue document also handy for Network Security People. • Research alternative ways to ensure network security.

  9. Contributions received so far • German Aerospace Centre • Workflow driven firewall control requirements. • Forchungs Zentrum Juelich • Authorization requirements • Argonne National Laboratory • Why Gridftp needs a firewall “garage door opener” • External clients using WS End Point References behind a firewall • University of Amsterdam • Integrate firewalls long haul optical (peer) connections. • Using EAP as garage door opener • Your contribution?

  10. Example: gridftp • Firewall administrators don’t want to open 1002 holes in their firewall. Any questions ? • Globus recommends to open ports 50.000-51.000 (1001) • Gridftp: single control channel port (2811) & multiple data ports in Globus port range. • Protocol requires that the sending side do the TCP connect. • Information which port(s) will be used is known at last moment. • 8 streams per file-transfer has proven to be reasonable. • Gridftp needs a “garage-door opener” for individual ports at time of transfer. Door must also automatically close. • Thinking about EAP style (like used in 802.1X WLANs) solution where you authenticate an application in stead of a user. Application profiles determine which holes are allowed.

  12. Future documents • Requirements towards standards bodies • IETF: NSIS, MIDCOM, EAP • Trusted Computing group: • Trusted Computing Architecture • EAP extensions for virus checking • Research into new directions • Token Based networking • High speed encryption • Workflow system integration • etc.
