Threat Modeling Methodology for Secure Development

This document is a guide outlining Bishop Fox's Threat Modeling methodology, which proactively addresses security issues throughout the software development life cycle. The process begins with stakeholder engagement to gather critical information regarding development processes, risk scenarios, and business objectives. Following this, dataflow diagrams are constructed to illustrate key processes and trust boundaries. The S.T.R.I.D.E framework is utilized for threat enumeration, identifying potential vulnerabilities such as spoofing and tampering. Mitigating controls are documented for each identified threat, including primary and secondary measures. The methodology emphasizes collaboration with stakeholders to ensure accuracy and promote secure design patterns. The final Threat Model is communicated to all parties involved, ensuring clarity in findings and validation of mitigating controls. This structured approach aims to facilitate ongoing iterations of the Threat Model in future development life cycles, enhancing the overall security posture of applications.
