Exploring New Methods for Protecting and Distributing Confidential Research Data Exploring New Methods for Protecting and Distributing Confidential Research Data Presentation Transcript

  • Exploring New Methods for Protecting and Distributing Confidential Research Data Bryan Beecher Felicia LeClere ICPSR/University of Michigan
  • Today’s Talk
    • What’s ICPSR?
    • How do organizations distribute confidential research data today?
    • What are the problems?
    • What can we improve?
  • What’s ICPSR?
    • Inter-university Consortium for Political and Social Research
      • JSTOR for social science data
    • Serving billions since 1962
    View slide
  • Who does ICPSR serve?
    • Research universities
      • Discover and download data
    • Teaching universities and colleges
      • On-line analysis
    • Federal agencies
      • Data management, preservation, and dissemination
    View slide
  • Distributing data
  • Distributing data
    • Most of our content is public-use
      • Anonymized public opinion
      • Aggregate government data
    • Little risk of disclosure
    • But what about the good stuff?
  • Distributing sensitive data
  • Distributing sensitive data
    • Higher risk of breech of confidentiality
      • Variables that give geographic information that might be combined with other data sources to identify a respondent
    • Requires special handling
  • Distributing sensitive data
    • Researcher agrees to protect the data and identities
    • Delivered securely
    • Harsh penalty deterrent

  • National Longitudinal Study of Adolescent Health
    • Add Health
      • Highly used and cited study
    • Very frank questions
      • Kids in 7 th through 12 th grade
    • Carolina Population Center
    • Gold standard in data protection
  • Traditional Approach http://www.flickr.com/photos/videolux/2389320345/ http://www.flickr.com/photos/curiousexpeditions/3767246490/
  • Traditional Approach Confidential research data Apply for access Write security plan Repeat
  • Can we improve upon it?
    • Paperwork
      • How do we speed the application process?
    • Security
      • How do we ensure the data are going to a good home?
  • Paperwork
    • Web portal
      • Research plan
      • IRB approval
      • CVs
      • Confidentiality agreements
  • Paperwork
    • Web portal
      • Behavioral questionnaire
      • Electronic copy of contract (HTML, PDF)
      • Database back-end to drive workflow systems
  • Restricted data Contracting System
    • Integrated with ICPSR’s existing Web download mechanism
    • Collects information that would ordinarily be provided through paper
    • “ Tickler” system to send reminders, nag about missing items
  • Security
    • Current system relies on…
      • The data provider to maintain security templates
      • The researcher to write an IT security plan
      • The data provider to read and understand the plan
      • The researcher to execute the plan
  • Current access model Researcher Workstation ICPSR
  • A new access model? Secure Area Researcher Workstation ICPSR
  • Secure area = the cloud?
    • Cloud-based access
      • Convenient
      • Scalable
      • Economical
      • Perfect?

  • What could go wrong?
  • Almost everything
    • Is the cloud reliable?
    • Will the data be safe?
    • We are building an analytic environment for a researcher, how will we know what to provide?
    • Will this perform well for the researcher?
    • This is the main story…
  • Cloud reliability
    • Already using the cloud for DR purposes since January 2009
    • The Merit Network Operations Center monitors all of our stuff
    • Ping, http GET every minute 24 x 7
    • Results?
  • Local v. cloud – CY 2009
  • Conclusion
    • Cloud has been more reliable than local environment
    • If local power was better, cloud would still be better, but only a little better
    • Certainly seems to be good enough
  • Cloud security
    • Absolute security?
      • Who cares?
    • More secure than the typical WinTel desktop of a social science researcher?
      • That’s the goal

  • Current practice
    • Data archive maintains per-platform guidelines on IT security
    • Researcher downloads a template and writes his/her own IT security plan
    • Data provider reviews plan; approves or iterates until approved or rejected
  • Sample items
      • I secured the computer on which the Add Health data resides in a locked room, or secured the computer to a table with a lock and cable (locking the case so the battery cannot be removed).
      • I turned off all unneeded services and disabled unneeded network protocols.
  • Brutal facts
    • Data providers are
    • not IT experts
    • Researchers are not
    • experts in IT security
    • Even if the system is secure on Day One, what assurance is there that it continues to be secure?

  • Our approach to security
    • Leverage tools from the cloud provider (AWS access control lists)
    • Leverage tools from UMich (regular Retina and Nessus scans)
    • Engage a white hat hacker to probe and evaluate the system
  • Conclusion
    • Expecting researchers to build and maintain secure IT environments is not reasonable
    • We think we can build something at least as secure in the cloud
    • We’ll evaluate our environment using outside evaluators
  • What to deploy?
    • Model means we need to distribute a working analytic environment, not just the data
    • Also gives the researcher the opportunity to limit access to only a subset of contractees
  • May I Take Your Order?
    • Operating system?
    • Analysis software?
    • Who’s allowed to use the system?
    • Anything else?

  • The ACI Chooser
    • Analytic Cloud Instance
      • Cumulus
    • The ACI Chooser
    • Takes your order
    • Brings your ACI to your table (in the cloud)
  • Conclusion
    • We’re building this now
    • Issues to resolve
      • How do we get passwords to people?
      • Remote access mechanism?
        • Citrix? Terminal Services?
      • Should we encrypt the data?
  • Performance
    • Will a cloud-based analysis system meet the expectations of a researcher?
    • Will one size fit all?
  • Amazon EC2
    • Regular
      • S (1 CPU, 2GB, $0.12)
      • L (4 CPU, 7GB, $0.48)
      • XL (8 CPU, 15GB, $0.96)
    • High memory
      • XXL (13 CPU, 34GB, $1.44)
      • XXXXL (26 CPU, 68GB, $2.88)
    • High CPU
      • M (5 CPU, 2GB, $0.29)
      • XL (20 CPU, 7GB, $1.16)
  • Strategy
    • Balance cost and performance
    • Start small, but give opportunity to grow
      • Easy to move an image from one instance size to another
    • Measure performance via researcher’s experience
  • Conclusion
    • Partners
      • Panel Study of Income Dynamics (PSID)
      • Los Angeles Family and Neighborhood Study (LA FANS)
    • Start small; re-launch larger
    • Ask how well it works
  • Thanks and Final Thoughts
    • Could preserve machine image + data + software + “program” for replication purposes
