Assurance Cases

As cyber-physical systems become increasingly complex, regulators and third parties are looking for a means of assessing various properties of these systems, such as safety and security, under increasing time constraints. One possible method of accomplishing this goal considers the use of a concept called Assurance Cases. Assurance cases are really nothing more than structured arguments that rely on evidence to justify a claim. They are based on practices steeped in centuries of philosophical discussion and most commonly demonstrated in the practice of law. The mission of this group is to:

• explore past and present work on developing assurance cases
• develop new ideas and leverage technology to argue properties of cyber-physical systems
• establish a body of knowledge on assurance case content, structure, and presentation
