value, but in this context are used to confi rm and demonstrate the robustness of a system designed and developed with a foundation of security.


Provide bidirectional traceability The IEEE Standard Glossary of Software Engineering Terminology defi nes traceability as “the degree to which a relationship can be established between two or more products of the development process, especially products having a predecessor-successor or master- subordinate relationship to one another.” Most functional safety standards require evidence of bidirectional traceability, which means that traceability paths are maintained both forward and backward. Automation with tools such as the LDRA tool suite makes it much easier to maintain traceability in a changing project environment.


Shift left in practice


Building security into the software life cycle from the start by following best practices familiar to developers of safety-critical applications is a cohesive and highly effective approach to developing safe, secure, and reliable embedded software for critical connected devices.
