Safety and security are major concerns with most non-trivial software-intensive systems, as hazards and threats raise the risk of accidents and attacks. Because requirements engineers, safety engineers, and security engineers do not know how to collaborate to produce proper safety and security requirements, systems are built with significant vulnerabilities that are difficult and expensive to fix. Security and Safety Requirements for Software-Intensive Systems addresses this issue by integrating these areas and providing enough basic information to allow for effective collaboration. With examples, this book provides a practical process for identifying, reusing, and managing requirements.
