Module aims

This module aims to provide students with an understanding of the interrelationships between safety and security. In particular the module focuses on how security threats can develop into hazardous events. The module is aimed at students with knowledge of safety engineering, but little or no understanding of security. The module therefore provides a broad awareness of security principles, measures and techniques.

Module learning outcomes

  • Identify and describe the implications of vulnerabilities in a system, using this to inform and challenge project decisions.
  • Assess the credibility of a proposed design, make justifiable trade-offs between security and safety requirements.
  • Assess the safety properties of a proposed system with consideration of security threats and vulnerabilities.
  • Develop an assurance case for the safety and security of a system or service.
