Software safety risk in legacy safety-critical computer systems
Proceedings 2007 IEEE SoutheastCon
Safety-critical computer systems must be engineered to meet system and software safety requirements. For legacy safety-critical computer systems, software safety requirements may not have been formally specified during development. When process-oriented software safety requirements are levied on a legacy system after the fact, where software development artifacts don't exist or are incomplete, the question becomes 'how can this be done?' The risks associated with only meeting certain softwaredoi:10.1109/secon.2007.342891 fatcat:oogwn3hhhvdv3cfds5si23zwwi
