            Current Challenges
• IT Security approach today is reactive, one-off,
  labor intensive and lacking useful data
• Most incident detection re: MIT computers
  comes from 3rd parties
• We have sparse data on MITnet’s uses
• Computers are not adequately protected from
  attack – from both inside and outside
• Compromises reduce productivity, put sensitive
  data and IP at risk, and lead to legal, financial and
  reputational harm

                                     Traditional View
       The Public Internet is wonderful, we should do everything possible to ENABLE
       computers on MITnet to access anything and everything on the Public Internet, and
       vice versa, and to think of MIT and MITnet as if they were simply a subset of the
       Public Internet, particularly from a policy point of view.




                                 The Public Internet


                                                       MITnet

                  Examples
• MIT does not comply with all provisions of MA
  Data Breach Law/Regulations, particularly in
  incident detection/response and forensics
• MIT complies with HEOA, but DMCA Notification
  volumes are soaring, so the measures used may
  not be enough, and we may need additional
  technological measures
• Isolating/protecting PCI computers (as well as
  other devices requiring VERY high protection)
  remains difficult.

            Guiding Principles
• Provide for standards in a decentralized
  environment
• Academic freedom, privacy and choice
• Technically sound, providing high reliability
• Improve visibility of network needs and issues
• Granularity – no more “one size fits all”
• Protect intellectual property
• Comply with laws and regulations
• Safer computing experience
• Fiscally prudent

                                     Future View
       By providing a more managed connection at the border between MITnet and the Public
       Internet, we increase the visibility of – and our understanding of – the threats and risks
       that are present, and then how to protect MIT computers and work areas on a very
       granular level.
