Soundness, evidence and discipline in high-assurance software
Roderick Chapman - Protean Code Limited
This talk will reflect on the need for soundness in software verification, and (more generally) the issue of trust in automated verification tools. If a tool vendor says their tool is "Sound", should you believe them? What does this really mean in practice, and what assumptions underpin such claims? If you develop trust in a tool, what effect does this have on engineers' behaviour and engineering process? Finally, we'll consider what role soundness plays for security claims in the face of an overtly malicious environment.
