Educause Annual 2007

  1. 1. <ul><li>Chaos to Clarity: Consolidate Your Security Information into a Knowledge Base </li></ul><ul><li>Joshua Drummond, Security Architect </li></ul><ul><li>Neil Matatall, Security Programmer/Analyst </li></ul><ul><li>Marina Arseniev, Associate Director of Enterprise Architecture </li></ul><ul><li>University of California, Irvine </li></ul>
  2. 2. About us… <ul><li>Located in Southern California </li></ul><ul><li>Year Founded:  1965 </li></ul><ul><li>Enrollment: over 24K students </li></ul><ul><li>1,400 Faculty (Academic Senate) </li></ul><ul><li>8,300 Staff </li></ul><ul><li>6,000 degrees awarded annually </li></ul><ul><li>Carnegie Classification:  Doctoral/Research – Extensive </li></ul><ul><li>Extramural Funding - 311M in 2005-2006 </li></ul><ul><li>Undergoing significant enrollment growth </li></ul>
  3. 3. Security Status Across Higher Ed? http://www.privacyrights.org <ul><ul><li>800,000 in November, 2006: Hacker(s) gained access to a database containing personal information on current and former students, current and former faculty and staff, parents of financial aid applicants, and student applicants. </li></ul></ul><ul><ul><li>5,800 in August, 2007: Computer with the SSNs of students was discarded before its hard drive was erased, forcing the school to warn students about potential identify theft. </li></ul></ul><ul><ul><li>4,375 on September, 2007: Former students at risk for identity fraud after an instructor's laptop computer was stolen. </li></ul></ul><ul><ul><li>3,100 on September, 2007: A technical problem in the way student bills are printed possibly allowed student SSNs to be sent to another student's address. </li></ul></ul>
  4. 4. Security is Multi-layer
  5. 5. We do a lot… SDLC and Change Management <ul><li>Security requirements and design reviews from get-go. </li></ul><ul><li>Code reviews </li></ul><ul><li>Developers reuse security components </li></ul><ul><li>Automated nightly code and application security scanning </li></ul><ul><li>Scheduled network & configuration vulnerability scanning </li></ul><ul><li>Consolidated storage of sensitive data, database model reviews of personal identity data </li></ul><ul><li>Concurrency and stress testing to detect thread security </li></ul>
  6. 6. Still had problems <ul><li>Urgent call from our director: </li></ul><ul><ul><li>Have you patched server X? </li></ul></ul><ul><ul><li>Is Server Y behind a firewall? </li></ul></ul><ul><ul><li>Did Server Y have any Credit Card information stored? </li></ul></ul><ul><ul><li>Is the database encrypted? </li></ul></ul><ul><ul><li>When was the last time a security review of Application X was done? </li></ul></ul><ul><li>Peter The Anteater is on vacation! </li></ul><ul><li>Peter is now at Google! </li></ul><ul><li>Different answers from different people. </li></ul><ul><li>Little confidence that information is current. </li></ul>
  7. 7. Not enough… <ul><ul><li>Many security layers meant many documents owned by many people </li></ul></ul><ul><ul><li>Scattered checklists, spreadsheets, and diagrams not accessible </li></ul></ul><ul><ul><li>Host IP change = document update nightmare. </li></ul></ul><ul><ul><li>New server?

  8. 8. What we learned … <ul><li>Maintaining separate spreadsheets on server configurations, firewalls, and personal identity data, each with redundant and inconsistent information, is inappropriate in today's security climate . </li></ul><ul><li>Explored different approaches and tools – both vendor and open source. </li></ul><ul><li>Merged with the Enterprise Architecture approach to use Stanford’s Protégé Knowledgebase. </li></ul><ul><ul><li>Open source ontology and knowledge-based tool, to intelligently capture and maintain comprehensive enterprise security information in a single repository. </li></ul></ul>

  11. 11. Background <ul><li>What is an Ontology? </li></ul><ul><ul><li>“ An ontology describes the concepts and relationships that are important in a particular domain, providing a vocabulary for that domain as well as a computerized specification of the meaning of terms used in the vocabulary. In recent years, ontologies have been adopted in many business and scientific communities as a way to share, reuse and process domain knowledge . Ontologies are now central to many applications such as scientific knowledge portals, information management systems, and electronic commerce. “ </li></ul></ul><ul><ul><li>Supports inheritable properties (is-a) </li></ul></ul><ul><ul><li>Attributes of an object can be complex objects themselves (rich). Nestable… </li></ul></ul>Writing Short Story Historical Novel Classic Medieval Modern Book Ontology
