Threat Modeling
Threat Modeling is a proactive security practice that identifies, evaluates, and mitigates potential threats to a system, application, or network. The objective is to anticipate and address vulnerabilities before they are exploited, enhancing the overall security of software development. Threat modeling considers an application’s design, potential attack vectors, user interactions, and data flows to identify potential security weaknesses.
Threat modeling typically follows these steps:
Define Assets and Boundaries: Determine critical assets (e.g., sensitive data, system components) and identify the boundaries of the system.
Identify Potential Threats: Consider all possible threats, such as unauthorized access, data breaches, denial-of-service attacks, or exploitation of vulnerabilities.
Assess Threat Impact: Evaluate how each identified threat could impact the system, including potential business, financial, or reputational damage.
Develop Mitigation Strategies: Plan countermeasures, such as encryption, access controls, and firewalls, to reduce or eliminate risks.
Review and Update: Regularly revisit the threat model, especially after significant software updates, to keep up with new threats.
Frameworks like STRIDE (Spoofing, Tampering, Repudiation, Information Disclosure, Denial of Service, Elevation of Privilege) and DREAD (Damage Potential, Reproducibility, Exploitability, Affected Users, Discoverability) are commonly used to categorize threats, helping developers to prioritize and address the most critical ones. With threat modeling, organizations can improve security defenses, minimize the risk of attacks, and protect their assets more effectively.
How CodeBranch applies Threat Modeling in real projects
The definition above gives you the concept — but knowing what Threat Modeling means is different from knowing when and how to apply it in a production system. At CodeBranch, we have spent 20+ years building custom software across healthcare, fintech, supply chain, proptech, audio, connected devices, and more. Every entry in this glossary reflects how our engineering, architecture, and QA teams actually use these concepts on client projects today.
Our work combines AI-powered agentic development, the Spec-Driven Development (SDD) framework, CI/CD pipelines with agent rules, and production-grade quality gates. Whether you are evaluating a technology for your product, trying to understand a vendor proposal, or simply learning, this glossary is written to give you practical, accurate context — not theoretical abstractions.
