  1. E-mail Defense System(a.k.a. Junk mail & Virus Filtering at the Server level)

  2. The problem today • 15 million virus messages go across NU’s network annually. • University constituents & NUIT are very concerned about the increase of junk mail & viruses, & the effect on productivity. • Webmail & handheld devices cannot benefit from desktop e-mail client junk mail filtering tools.

  3. What has NU been doing about this? • Information about client side filtering has been made available on the NUIT web site. • Conversations with NU Legal have been in process to ensure that server level filtering does not violate the pursuit of academic freedom. • NUIT has been monitoring the marketplace. It wasn’t until recently that a clear leader emerged at a price point that is acceptable to the University. • NUIT has conferred with peer institutions to learn from their experience. • Trial, purchase and deployment of Sophos PureMessage (a.k.a. NU’s E-mail Defense System) on our central e-mail servers.

  4. How will this help with viruses? • Stops an infected embedded message from getting to the desktop. • Automatically downloads the latest enterprise level virus definitions (versus current home grown system).

  5. What are the benefits? • Productivity increases (less time spent going through junk e-mail). • Webmail becomes a more useful tool. • Less chance of a user hitting the 50MB quota on the e-mail server. • Increased network security.

  6. How does it work?

  7. EDS Deployment plan • Virus filtering started May 2005. • Phase 1: Further refine system set up parameters with input from “key early adopters” (July 2005) • Three groups: • Faculty/Staff/Graduate students: 48%-100% probability quarantined. • Undergraduates: 48%-94% probability quarantined, 95%+ rejected. • Alumni: 50%+ probability rejected, no quarantine. • Quarantine kept 7 days (can increase to 120 days). • Digest of junk sent to users overnight. • Individual “approved” and “unapproved” lists. • Users may need to continue to use client side junk mail filters.

  8. EDS Deployment plan • Phase 2: Expand early adopters list to include technical support staff throughout the University. (August 2005) • Implement campus wide education plan (including how to easily opt out of the service and how to use client side filters with server side filters). • October 3rd, 2005 “full launch”.
