Explore a comprehensive approach to secure software development in this conference talk from OWASP AppSec EU 2018. Delve into the Secure Software Development Framework (SSDF), an innovative methodology designed to integrate security practices across various Software Development Life Cycles (SDLCs). Learn how this framework adapts to Waterfall, Iterative, and Continuous Deployment methodologies, offering flexibility without compromising security. Discover techniques for eliminating redundancy, clarifying requirements, and enhancing efficiency in the development process. Gain insights into embedding secure architecture, design, development, and validation activities throughout the software lifecycle, making it easier for developers and architects to adopt robust security practices.
