The software industry has been struggling with how to create and release software that is more security- enhanced and reliable - the Security Development Lifecycle (SDL) provides a methodology that works. Adapted from Microsoft's standard development process, SDL is a critical way to help reduce the number of security defects in code at every stage of the development process, from design to release. Co-authored by Michael Howard and Steve Lipner, you get direct access to insights from Microsoft's security team and lessons that are repeatable and applicable to software development processes worldwide, whether on a small-scale or large-scale. This book includes a CD featuring videos of developer training classes.
