Safety Certification and Security

A couple things that are imperative in society and in just plain life – safety and security – are just as important in the embedded computing realm. From avionics to automobiles to spacecraft to the manufacturing plant, we all like to know we're safe from physical harm caused by ... Moremechanical equipment failures. In the avionics realm, electronics safety criticality is ensured by the FAA's safety certification standards called DO-178B and DO-254, for example. In the outside plant or central office, NEBS compliance is likewise vital. However, in the security-critical world, military Intelligence, Surveillance, and Reconnaissance (ISR) and net-centric systems used by DoD Command and Control (C2) must be hack-proof to protect our soldiers' lives – and our national security. Multiple Independent Levels of Security (MILS) and virtualization-scheme partitioning can be used to help prevent security infractions and work by invoking a separate partition for each application, thus separating applications with varying classification levels and providing users access only to the applications for which they are authorized. And lastly, though perhaps not necessary for all secure applications, Common Criteria certification additionally means the application has gone through rigorous security testing.
