ISO/SAE 21434 Final International Standard was released September 2021 to great fanfare and is the most prominent standard in Automotive Cybersecurity. As members of the Joint Working Group (JWG) we spent 5 years developing the 84 pages of precise wording acceptable to hundreds of contributors, during which time the auto industry had been undergoing a metamorphosis probably unmatched in its hundred-year history. ...The application to an Agile method may require interpreting the standard from another angle, which could involve reordering the sequence of activities and work products, breaking down the acceptable criteria of some work products to allow rapid iterations, and verifications of meta data or intermediate work products. In cybersecurity engineering, the Agile method has its unique strength comparing to the V-model method, as its cyclical nature is better aligned with best practices for Cybersecurity Frameworks ...In cybersecurity engineering, the Agile method has its unique strength comparing to the V-model method, as its cyclical nature is better aligned with best practices for Cybersecurity Frameworks
