Security in High Reliability Applications: Is it safe?

Security in High Reliability Applications: Is it safe?Increasingly in this modern world, we rely on systems where an error could cause financial disaster, organisational chaos, or in the worst case death. Software now plays a crucial role in these systems, but the disturbing fact is that the increasing use of embedded computers, controlling all sorts of devices, is moving us in the opposite direction.
Organisations like ‘Which?’ in the UK devote their energies to examining such devices. They test them thoroughly, but importantly they also examine and dismantle the devices to detect engineering defects, such as unsafe wiring. If they find a device unsafe it is rated as unacceptable and the public is protected against the dangerous device. But as soon as embedded computer systems are involved we have no such transparency. Cars, for example, are now full of computers and without access to the software details, there is no way to tell if these cars are ‘Unsafe at Any Speed’.
