What About Open Source? • Several open source implementations of TNC • University of Applied Arts and Sciences in Hannover, Germany (FHH) http://tnc.inform.fh-hannover.de • libtnc https://sourceforge.net/projects/lib/tnc • OpenSEA 802.1X supplicant http://www.openseaalliance.org • FreeRADIUS http://www.freeradius.org • TCG support for these efforts • Liaison Memberships • Open source licensing of TNC header files

  21. Summary • Network Access Control provides • Strong Security and Safety • Tight Control Over Network Access • Reduced PC Administration Costs • Open Standards Clearly Needed for NAC • Many, Many Vendors Involved in a NAC System • Some Key Benefits of Open Standards • Ubiquity, Flexibility, Reduced Cost • TNC = Open Standards for NAC • Widely Supported – HP, IBM, Juniper, McAfee, Microsoft, Symantec, etc. • Can Use TPM to Detect Root Kits • TNC: Coming Soon to a Network Near You!

  43. Per-User URL Filtering Stewart Duncan Technical Manager

  44. Current URL Filtering • LGfL URL Filtering Service is based around the NetSweeper Product • Policies can currently be configured by IP address and time of day • Reporting features are available to report on IP based sessions

  45. What is required? • Schools and LAs would like to identify end users for reporting • Have the ability to setup different policies for individual users or groups of users • IT Managers and Head Teachers need the ability to track URL traffic for an individual rather than a specific IP address

  46. What are LGfL doing to help? • LGfL working with Synetrix and Atomwide to enable the platform to offer Per-User /Group level Filtering • Enabling the USO to link with the NetSweeper Platform • Allow local management of User Policies through a web based front-end

  47. Where we are so far • A trial is currently taking place in various locations across London • So far the trial is going well and bugs are being identified and cleared up

  48. What does it Look like? The new front end allows configuration of multiple groups each with a separate policy.

  49. What does it Look like? Here you can configure which users belong to which policy within the USO.

  50. What does it Look like? Users are then prompted to log in when they run Internet Explorer and try and access the web.
