E-mail Defense System(a.k.a. Junk mail & Virus Filtering at the Server level)
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?• 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?• 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?• 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.
How does it work?
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 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”.
