2. Requirements Engineering and SWEBOK and SEBOK Guides

   • Software requirements and security
   • INCOSE certifications for systems engineers

3. Introduction to the STAMP Model (System-Theoretic Accident Model and Processes)

   • Use of the STAMP model in various industries
   • Safety and security
   • Causality and accident causality models

4. Introduction to STPA Technique (System-Theoretic Process Analysis)

   • Abstraction
