Software Design Trends Supporting Multiconcern Assurance

Complex software systems have become increasingly entwined in a wide variety of systems, such as critical infrastructure, industrial control systems, medical devices, automobiles, airplanes, and spacecraft. Assuring the security and safety, as well as other dependability concerns, such as availability, robustness, and reliability, of software-intensive systems remains among the top priorities for governments and providers of critical systems and services. Manufacturers, owners, and operators of the components and devices that make up these software systems strive to ensure that they have adequately addressed emerging concerns related to safety hazards, security threats, and performance challenges, among others.
