From the braking system in automobiles to the software that controls aircraft, safety-critical systems are ubiquitous. Showing that such systems meet their safety requirements has become a critical area of work for software and systems engineers. The SEI is addressing this issue with a significant research program into assurance cases. In this podcast, the first in a series on assurance cases and confidence, Charles Weinstock introduces the concept of assurance cases and discusses how they can be used to assure that complex software-based systems meet certain kinds of requirements such as safety, security, and reliability.
