Maintaining Separation for Security and Safety in Mixed Criticality Systems
Functional safety standards including IEC 61508 (generic safety related systems), ISO 26262 (automotive) and IEC 62304 (medical devices) generally categorise systems and subsystems in terms of their criticality, where an integrity level for a safety function is dictated by the properties of associated hazardous events. The decomposition of Functional Safety Requirements permits less critical subsystems to be assigned lesser integrity levels to help to reduce cost and effort, but it must result in design elements of sufficient technical independence. The whole of the assignment of integrity levels implies an assumption of separation such that the most critical subsystems cannot be compromised by those of lesser criticality. For a connected system in particular to be considered functionally safe, the separation between subsystems is paramount. This paper will discuss the role of secure software coding techniques in ensuring that such separation cannot be compromised.
