TNC 2006, Catania2 Credits Working group supported by Internet2 Kevin Miller (Duke University) Chris Misra (U. Massachusetts) Andy Rosenzweig (Merit Network) John Vollbrecht (Merit Network) Jessica Bibbee (Internet2) Steve Olshansky (Internet2) Renee Frost (Internet2) and all the brave semimonthly participants

TNC 2006, Catania3 History of edu-roaming  RADIUS proxy used by Merit Network for modem pools  IEEE 802.1x ratified in June 2001 RADIUS proxy for WLAN at University of Utah TERENA creates TF-Mobility in 2003 First eduroam enabled Access-Point in Zagreb (Croatia), May 2003 Internet2 creates FWNA in December 2004 eduroam.us, first International test in April 06 at Internet2 member meeting

TNC 2006, Catania4 What is FWNA? An Internet2 working group evaluating: -how 802.1x can be used to roam between institutions (local/global) -the implications of roaming (technology, policies,…)  An experiment that has Root RADIUS servers connected to US based schools as well as Europe and Asian-Pacific R&E networks.  Another name for eduroam.us

TNC 2006, Catania5 Why FWNA/eduroam.us ? We had open wireless networks We have been asked to secure those networks  We are now asked to open them again while maintaining an adequate security (visitors)  Somehow guest accounts are not good enough

TNC 2006, Catania6 Where is FWNA today Architecture RADIUS hierarchy modeled after eduroam.eu 802.1x only Experimental service in place Top-level servers at UTK and Merit Servers connected to Europe, Asia-Pacific A few US based institutions have joined Top-level tools being developed Web-based registration for connectors RADIUS proxy blocking mechanisms (realm, MAC)

TNC 2006, Catania7 The State of EDUROAM

TNC 2006, Catania8 Challenges of FWNA (…or challenges of 802.1x!)  No easy method of communication with users (layer2, no portal)  Decentralized and complex troubleshooting, lack of control (no adequate blocking)  AP roaming requires long distance re-auth (partially solved in i)  Policies are limited (but network control knobs are limited too!)  Low adoption rate of 802.1x in the USA

TNC 2006, Catania9 FWNA next steps  Operational:  explore other architectures (RADSec, Diameter, DNSSec)  Improve 802.1x controls from RADIUS (local/global) to NAS (Switch, Wireless AP, …)  Policies:  Stature (Trusted Network Connect (TNC), NAC, NAP)  User Privileges (when in Rome do as the Romans?)

TNC 2006, Catania10 Other uses of FWNA Sensornets Sensors may be more “mobile” than people not a EDU-person, but a EDU-gear! What EAP could be used? How additional facts can be provided? the other AAA (Availability, Ability, Authentication)

TNC 2006, Catania11 How to join FWNA? Must be willing to experiment; nothing is plug and play Important for experimenters to give feedback by way of pointers, local cookbooks, EAP trial info, etc. If you want to be an experiment site, send to: also visit to registerhttp://fwna.ns.utk.edu
