This talk, led by Mr. Tim Crumbley, explores the critical role of Software Assurance in ensuring that software is free from vulnerabilities—both intentional and accidental—throughout its lifecycle. Aimed at professionals and students in software engineering, particularly within the aerospace sector, the presentation will highlight NASA's comprehensive approach to software assurance and safety. Attendees will gain insights into NASA's definitions, activities, and requirements for implementing systematic software assurance, safety protocols, and Independent Verification and Validation (IV&V) for software created or maintained by NASA.
