It details an application development process from its inception through its development and testing process and covers concepts like secure programming, risk assessment, and threat modeling and how to integrate these practices into a secure software development life cycle. The authors also cover authentication and authorization, access control, cryptography, logging, and secure coding practices, as well as application exploits and vulnerabilities and related options and protection mechanisms, and measures to meet various security compliance requirements.
