  5. 5. Conjectures <ul><li>Organizations reduce preservation risk by: </li></ul><ul><ul><li>Providing systematic redundancy across diverse … </li></ul></ul><ul><ul><ul><li>Technical approaches: software, hardware, formats </li></ul></ul></ul><ul><ul><ul><li>Institutional environments: funding models, legal regime </li></ul></ul></ul><ul><ul><ul><li>Institutional control: curation, deaccessioning </li></ul></ul></ul><ul><ul><li>Enhancing preservation readiness: </li></ul></ul><ul><ul><ul><li>Awareness of risks and risk management approaches </li></ul></ul></ul><ul><ul><ul><li>Awareness & use of best practices </li></ul></ul></ul><ul><ul><ul><li>Active exercise of cataloging information, licensing terms, API’s </li></ul></ul></ul><ul><li>Trust and evaluation should be based on: </li></ul><ul><ul><li>Linking policy objectives to explicitly-defined roles, actions, and expected outcomes </li></ul></ul><ul><ul><li>Continuous evaluation and monitoring based on organizational incentives, capacity, & commitments </li></ul></ul>Building Communities of “Trust”
  6. 6. One tool… SAFE-Archive Policy-Based Replication & Auditing <ul><li>Facilitating collaborative replication and preservation with technology… </li></ul><ul><li>Collaborators declare explicit non-uniform resource commitments </li></ul><ul><li>Policy records commitments, storage network properties </li></ul><ul><li>Storage layer provides replication, integrity, freshness, versioning </li></ul><ul><li>SAFE-Archive software provides monitoring, auditing, and provisioning </li></ul><ul><li>Content is harvested through HTTP (LOCKSS) or OAI-PMH </li></ul><ul><li>Integration of LOCKSS, The Dataverse Network, TRAC </li></ul>Building Communities of “Trust”
  7. 7. Storage Layers Other than LOCKSS Building Communities of “Trust” System Risks Advantages LOCKSS <ul><li>Single implementation </li></ul><ul><li>Small installed base </li></ul><ul><li>Small development community </li></ul><ul><li>Scalability </li></ul><ul><li>Designed for preservation </li></ul><ul><li>Fault-tolerant </li></ul><ul><li>Minimal trust model </li></ul><ul><li>Harvesting functions </li></ul>IRODS <ul><li>Single implementation </li></ul><ul><li>Small installed base </li></ul><ul><li>-Small development community </li></ul><ul><li>-Complexity of rules system </li></ul><ul><li>-No integrity built in (use ACE?) </li></ul><ul><li>Flexible rules </li></ul><ul><li>Scaleable </li></ul>GnuNet, Freenet, Tahoe-LAFS <ul><li>Complexity of integration </li></ul><ul><li>No support for versioning </li></ul><ul><li>Fault tolerant </li></ul><ul><li>Moderate installed base </li></ul><ul><li>Multiple implementations </li></ul>CrashPlan SpiderOak Mozy <ul><li>Closed source </li></ul><ul><li>Difficult to integrate with </li></ul><ul><li>Licensing fees </li></ul><ul><li>Multiple implementations </li></ul><ul><li>Extensive target storage support </li></ul><ul><li>Extensive reporting </li></ul><ul><li>Commercial support </li></ul>
  8. 8. Why this tool? <ul><li>To facilitate institutions in making commitments aligned with their policies and incentives, and </li></ul><ul><li>Automatically execute and monitor those commitments and policies </li></ul><ul><li>Support Data-PASS partnership agreements and transfer protocols </li></ul><ul><li>This tool provides a thin slice of functionality through the entire policy stack… </li></ul>Building Communities of “Trust”

  14. 14. Evaluation Levels <ul><li>Do documented policies & procedures exist? SAS 70 Type I : point-in-time; controls in operation; documented/presented; suitable for control objective </li></ul><ul><li>Are operations consistent with policies and procedures? SAS 70 Type II: tests of control effectiveness over time </li></ul><ul><li>Do policies and procedures reflect appropriate/good/best practices in place to obtain objectives? FISMA Certification: evaluates objectives, threats, vulnerabilities, recommends controls </li></ul><ul><li>Are objectives, goals, mission, values consistent? Examples: CRL, charity navigator </li></ul><ul><li>Does institution have the fitness to honor commitments? Examples: CRL, Standard & Poor’s, Moody’s </li></ul>Building Communities of “Trust” System Analysis Threat Modeling Vulnerability Identification Analysis - likelihood - impact - mitigating controls Institute Selected Controls Testing and Auditing Information Security Control Selection Process
  15. 15. What can we Learn from Open Source Dev <ul><li>Most OSS projects have limited success, at best </li></ul><ul><ul><li>Most fail/expire </li></ul></ul><ul><ul><li>Most have single/small group of developers </li></ul></ul><ul><li>If you build it, users may come </li></ul><ul><ul><li>Developers may come if people who use your tool also develop it </li></ul></ul><ul><li>Incentives </li></ul><ul><ul><li>Ego </li></ul></ul><ul><ul><li>Reputation </li></ul></ul><ul><ul><li>Linked to job incentives </li></ul></ul><ul><li>Structure </li></ul><ul><ul><li>Have a leader (or small cabal) at any point in time </li></ul></ul><ul><ul><li>Transparency </li></ul></ul><ul><ul><li>Governance is linked to participation </li></ul></ul>Building Communities of “Trust”
