About this pressentation

The first reported cyber-attack on a Safety Instrumented System demonstrates that systems important to safety need cyber security measures to avoid their safety arguments being invalidated. But there is a broader justification: cyber security risks arise as a direct result of the nature of networked digital technology, which renders existing safety analysis inadequate to mitigate those risks. Existing standards recognise that safety and security practices need to work together but detailed, procedural best practice is not yet mature. The paper reflects on why cyber security is such a challenge, why safety analysis does not automatically cover cyber security and what current guidance does tell us. It then identifies some specific areas where industry thought-leaders could share how they are dealing with this topic and the paper finishes with a question about the ethics of using of the most advanced networked digital technologies in systems that are important to safety. In considering these topics, the paper draws broadly on experiences in civil nuclear and hazardous industries, where networked digital technology is being adopted for pressing commercial reasons.
