Introduction to Safety Security

TU Delft | 2017-2018 Academic Year, 2nd Quarter | Dr. Frank Guldenmund
Leiden University catalog number: 5000MRI12


Course Description

Introduction to the field of risk and safety/ security based on various texts (book, scientific papers and book chapters). In the course, safety is considered from the perspective of the safety/ security manager working in a company facing multiple safety/ security risks.

In this course, students will be introduced to safety and security risk management as it is applied in organisations. The focus is on how organisations can make (responsible) decisions on safety and security, using the concepts of risk. Students learn to understand and use the concept of risk in safety and security settings, being aware of its benefits and limitations. They acquire practical knowledge and skills that allow them to analyse decisions made by risk managers, as well as various reports on risk/ safety topics in media. The course starts with safety risk first (accidents), and then extends its scope to security risks (threats and attacks).

The following topics will be covered:

  • Introduction of important safety and risk concepts, such as probability, frequency, hazard/ threat, vulnerability, impact/ consequence

  • Quantitative and qualitative assessment of safety and security risks in organisations
  • Several risk analysis techniques such as fault/ attack trees, HBT-model and bowties
  • The psychology of safety and security, human error
  • A systemss view on safety/ security and SADT-analysis

  • Explain the similarities and differences between safety and security risks and their assessment
  • Understand the tasks and responsibilities of the safety/ risk manager or professional
  • Apply several safety and security risk analysis techniques such as fault and attack trees
