  1. NIST SAMATE Project and OMG Michael Kass NIST Information Technology Laboratory http://samate.nist.gov March 11, 2008

  2. Overview • NIST SAMATE Project • Testing the Tools • Automated Test Case Generation • CWE Formalization • SAMATE and CWE Effectiveness Program • TCG: Where are we now? • Other SAMATE work

  3. SAMATESoftware Assurance Metrics and Tool Evaluation Project • Co-sponsored by DHS to: • Create tests and tool specifications for software assurance (SwA) tool evaluations • Develop metrics for measuring SwA tool effectiveness • Identify gaps in current SwA technology • Make recommendations to DHS for areas of research

  4. Testing the Tools • SAMATE Reference Dataset (SRD) • Online repository of tool tests • Thousands of source code samples containing examples of CWE’s • Discrete tests – developed by NIST, contributed by tool developers, academia and public • Tests are based upon interpretation of a particular weakness definition (currently no formal white-box definitions) • Tests are freely available at http://samate.nist.gov/SRD

  5. Formal CWE Definitions (SBVR/KDM) Automated Test Case Generation (TCG) KDM • Funded by DHS • Part of SAMATE effort to expand SRD to cover as many CWE’s as possible • Based upon OMG MDA Technology (MOF, UML, XMI) • Uses formalized CWE definitions (SBVR) • Contractual Formalization that is based on OMG standard, Semantics of Business Vocabulary and Rules (SBVR) and • Technical Formalization that is based on OMG standard, Knowledge Discovery Metamodel (KDM) Code Analysis Tool Tool Tests (code)

  6. CWE Formalization • White Box Definitions : Focus on the structure patterns of the inner components and their interactions (that determine certain observable behavior) • Provide “compliance points” that: • Describe patterns of code (as they can be directly identified in code) • Identify discernable properties of patterns of code • Enable automation • Enable direct step-by-step comparisons of the decision procedures implemented within tool

  7. SAMATE and CWE Effectiveness Program • Long-term goal : To auto-generate tool tests using formal CWE definitions in collaboration with MITRE’s CWE Effectiveness program • Provide tests “ad hoc” to tool developers • Developers run tests against their tool • Developers can publish test results

  8. TCG: Where are we now? • TCG Status: • Can generate tests for 3 CWE’s • Near term, NIST will expand formal CWE definitions to 25 “high priority” CWE’s based upon their: • Occurrence • Severity • Recognized by tools today • Long term, TGC will cover as many CWEs as possible • With coding complexities

  9. Other SAMATE Projects • Ongoing work • Developing tests for web application scanners • Adding to existing tests for source code security analyzers • Performing tool effectiveness studies • New areas • Testing binary analyzers • The static analyzer tool exposition (SATE) • Software transparency/pedigree information • Malware research protocols
