Unfortunately, many well-established classifications and taxonomies of system errors are not what we would term operationalized (i.e., directly usable in modern, model-based system engineering efforts). Instead, they...

As computers become more powerful and ubiquitous, software and software-based systems are increasingly relied on for business, governmental, and even personal tasks. While many of these devices and apps simply increase the convenience of our lives, some--known as critical systems--perform business- or life-preserving functionality. As they become more prevalent, securing critical systems from accidental and malicious threats has become both more important and more difficult. In addition to classic safety problems, such as ensuring hardware...
