This talk contextualized cyberwarfare with patterns of conflict throughout history. While the basic nature of war is constant, the means and methods we use evolve continuously. Agile development is now 20 years old and industry practice has evolved to DevSecOps. We explained what DevSecOps is, and why it is critical to the time-competitive cybersecurity environment of today. Most importantly, we demystified how NATO can utilize the U.S. DoD DevSecOps reference architecture to easily and quickly adopt DevSecOps for platform environments and mission applications.
