Threat model overview

Software threat modeling is a systematic approach to identifying and mitigating potential security threats in a software application. The goal is to proactively identify and address security vulnerabilities before deploying the software. Threat modeling helps developers, architects, and security professionals understand the potential risks to a system and implement appropriate security controls. Here is an overview of the critical steps involved in software threat modeling:

1. Define the scope:
   • Clearly define the boundaries and components of the system you are analyzing.
   • Identify the assets, such as sensitive data or critical functionality, that need protection.
   • The function design phase we discussed in Chapter 2 addresses this step.
2. Create a system overview:
   • Develop high-level diagrams of the system architecture.
   • Identify the main components, interfaces, and data flows within the system.
   • The object, dynamic, and system design phases we discussed in the...
