the problem today

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.
what has nu been doing about this

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.
how will this help with viruses

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).
what are the benefits

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.
eds deployment plan

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.
eds deployment plan1

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”.
