Safety Architect and Cyber Architect Tools in AMASS

Share this post :

The AMASS consortium has chosen to build the AMASS Tool Platform around existing open technologies, e.g OpenCert for management of assurance and compliance, and Papyrus and CHESS for system component specification. The AMASS Tool Platform also provides interoperability features with other tools used by the AMASS consortium to address the project objectives, such as a multi-concern assurance. System dependability co-analysis/assessment, and particularly system safety and security co-analysis, is an integral parts of multi-concern assurance aspects.

Safety Architect and Cyber Architect are ALL4TEC tools that provide an integration features with the AMASS Tool Platform for system safety and security co-analysis. Thanks to this integration, Safety Architect and Cyber Architect provide a comprehensive way to reduce the gap between safety and security analyses and system architecture assurance. From CHESS models of a system architecture, Safety Architect allows performing a local FMEA of each architecture component and automatically deduces system-global FMEA/FMECA tables and fault trees of identified feared events. Safety Architect can be combined with a company dedicated FTA tools, such as Reliability Workbench FaultTree+ or Arbre Analyste for quantitative risk analysis. In addition, thanks to the security viewpoint in Safety Architect, assurance engineer can use the results of security analysis realized in Cyber Architect (e.g., vulnerabilities and threats analysis) to co-analyse safety and security risks and to generate merged safety and security artifacts, such as Failure Mode, Vulnerabilities and Effect Analysis (FMVEA).

The integration scenario between the AMASS Tool Platform + CHESS tools and the Safety Architect and Cyber Architect tools for safety and security co-analysis is presented below.
