In this podcast episode, Nandita Rao Narla explores the reasons why privacy threat modeling programs often fail, such as being expensive with a lot of friction in the development lifecycle, misalignment with organizational strategies focused on compliance rather than risk, and difficulty demonstrating a clear return on investment. Nandita highlights some successful strategies, including leveraging existing security threat modeling resources, simplifying the approach for better adoption like Adam Shostack's four-question framework, aligning with organizational values and culture, and encouraging a mindset of considering what could go wrong. The role of tooling in privacy threat modeling is discussed, with most organizations currently not using many dedicated tools beyond data mapping and asset discovery, while larger companies with mature programs may utilize more advanced tooling. Ultimately, privacy threat modeling represents the next frontier, with a strong privacy program partnering with security threat modeling being the next generation approach.

Akira Brand joins Chris to talk about her journey into threat modeling, her early experiences, some lessons learned, and how she knew her threat model was successful. Akira's experiences emphasize the importance of collaboration, understanding the application, and using tools and diagrams to aid the process.

Akira is a visual thinker and draws parallels between surgical checklists and the STRIDE model. Akira emphasizes the importance of a comprehensive approach, likening the STRIDE model to a surgeon's checklist that ensures all potential threats are addressed.

In her initial foray into threat modeling, she identified a significant security risk due to excessive permissions in an application. To understand and address this, she delved deep into the application's architecture, relying on data flow diagrams and a hands-on approach rather than a purely theoretical one.

Akira's story underscores the power of collaboration. Her challenges were overcome by the combined efforts of teams from engineering, data analytics, and security. She believes that the true measure of success in threat modeling is when diverse teams come together to create holistic security solutions.

Dr. Michael Loadenthal specializes in threat modeling beyond the conventional realm of technology. Companies today face multifaceted challenges, including political, legal, and technical threats. Solutions to these problems can also be varied. A comprehensive threat model should consider many dimensions, such as political, legal, ethical, and social. Whether advising activist groups or high-profile individuals, Dr. Loadenthal emphasizes a comprehensive understanding of the threat landscape and the development of context-specific solutions.

Dr. Loadenthal's unique approach to threat modeling is rooted in his early involvement in social movements and activism. He noticed that groups often faced many non-technical threats, such as legal, social, and political challenges. This realization led him to develop "intersectional threat modeling," which considers a broader spectrum of threats beyond just the technical.

Based on his diverse training and experience, Dr. Loadenthal emphasizes the importance of a multidisciplinary approach. He collaborates with a diverse team of specialists, including advisors and the clients themselves, to address complex challenges. Threat modeling works best with a team, and he discusses ways this works for him.

One of the tools in Dr. Loadenthal's multidisciplinary toolbox is the mind map. A mind map can show relationships between threats and lead to integrated solutions that address multiple problems together. A tool he likes to use from outside the tech industry is the harm reduction framework, a concept borrowed from public health. This approach acknowledges the inherent risks in various activities or systems but seeks to minimize the potential harm. Dr. Loadenthal explains how he applies the harm reduction framework to threat modeling. He shares practical examples of companies, non-profits, and high-profile individuals who all benefit from the broader perspective of his intersectional threat modeling.

The AppSec community agrees that threat modeling is essential, but many struggle to implement it effectively. Using insight from the LinkedIn community, Chris lays out a comprehensive Threat Modeling strategy to guide AppSec teams to success in this critical discipline.

Before starting, consider the organization's culture, tech debt, and current risk posture. Threat modeling will not be successful in an organization that doesn't prioritize security!

Tie threat modeling to the success of the business. See it as an enabler for the company, and define its success metrics clearly.

Integrate threat modeling into the development process in an agile and incremental manner. It's not about where you start but where you end up. It's essential to begin with critical applications and expand the scope over time.

Keep the Threat Model Up to Date. Threat modeling is a continuous process that adapts to new threats and system changes.

Make threat modeling holistic and straightforward. Start after the high-level design phase, and revisit the model continuously throughout a product's lifecycle.

Concentrate on domain-specific problems, which threat modeling is good at identifying. However, when identifying domain-agnostic issues, use automated approaches.

Engineering-led, developer-focused, or software-centric threat modeling: they all have software in common. Composing software into functions through the user story's lens is important. Farshad Abasi shares his journey from being a software engineer to forming a global AppSec team at HSBC Bank. Farshad expresses the importance of asset-based threat modeling and the need to keep things simple. He emphasizes the importance of focusing on the user story and considering the "comma, but" scenario to understand potential threats. He also suggests using pull request templates in source control to ask standard threat modeling requirements-specific questions.

Farshad recommends doing architectural threat modeling at the beginning of the development process and revisiting it periodically, perhaps quarterly or annually. He also highlights the importance of being part of the DevSecOps process to review user stories regularly.

The key points are asset-based threat modeling, following the data, focusing on the user story, balancing high-level architecture threat modeling at the right time, and adopting pull request templates as reminders for threat modeling.

Provide a solid process that makes sense to developers, as they don't mind threat modeling when presented in this way.
