Why we threat model

The threat landscape is continuously evolving. New attacks and vulnerabilities emerge nearly everyday, making it challenging to build secure systems. This is why we threat model.

Threat modeling is the "measure twice, cut once" of cybersecurity. It's a structured process that helps you see the big picture, so you can create targeted defense strategies. By methodically analyzing components, data flows, trust boundaries and more, threat modeling reveals security design flaws and high-risk areas.

The key benefits of threat modeling include:

  • Find bugs early: Fixing flaws late in development is costly. Find them upfront through threat modeling.
  • Understand security needs: Threat modeling highlights where defenses should focus, saving time and resources.
  • Build better systems: Design secure architecture by identifying risks before implementation.
  • Meet deadlines: Prioritize risks and guide security efforts where they matter most.

Who is this course for

Threat Modeling Intensive (222) Self-Paced is designed for software developers, architects, product managers, and security professionals who want to gain a deeper understanding of threat modeling concepts and methodologies. 

Relative to our Threat Modeling Essentials Course


Threat Modeling Essentials focuses on teaching a single method to address Four Questions. In our Threat Modeling Intensive, we add more methods to address each, and learn to assess which to apply. That includes state machines and message diagrams to express what we're working on, kill chains and attack trees to address what can go wrong, and risk management approaches to bring more nuance to what we're going to do about each. Intensive also has a set of optional videos and exercises to allow students to go further.

Threat Modeling Intensive (222) Self-Paced is ideal for those who:

  • Want to consistently apply threat modeling on projects to build more secure products
  • Need a comprehensive understanding of threat modeling frameworks like STRIDE and attack trees 
  • Are looking for more advanced threat modeling techniques like kill chains and risk analysis

Course overview

Threat Modeling Intensive is our most popular course. Its designed to provide attendees the ability to more consistently and efficiently apply threat modeling using the Four Question Framework:

  • What are we working on?
  • What can go wrong?
  • What are we going to do about it?
  • Did we do a good job?


Course content

  • Threat Modeling Lessons from Star Wars (Traps people fall into)
  • Answering the Question: what are we working on with DFDs and other tools
  • Figuring out what can go wrong using STRIDE and Kill Chains
  • Deciding what we’re going to do about it (Appropriate controls and risk management)
  • Determining if we did a good job through measurement and retrospectives
  • Threat modeling in 2021


What to expect 

Participants will complete 7 chapters including: 1 preparation, 5 knowledge and skills, and an optional chapter. The 6 core chapters each include a set of video lectures (about 5 minutes each) and exercises to build the skills covered in the lectures. There is also 1 chapter with 1 additional reading and 2 videos of 45 minutes each.

Learning outcomes

A transparent cube with a lockDescription automatically generatedAfter taking Threat Modeling Intensive, participants will, like those who take our Threat Modeling Essentials, have the knowledge and skills to consistently and efficiently use the Four Question Framework. That includes data flow diagrams, STRIDE and mitigation techniques, and the ability to choose between them for specific situations. They will also understand how to document results, and drive threat modeling results for action.

Participants in this Threat Modeling Intensive course not only learn specific skills, they learn more skills, including kill chains and risk management. They go deeper into each, and evaluate why those skills make sense, and learn about some of the challenges that they may encounter in their day-to-day application of those skills.

After taking this class, participants will have a depth of knowledge and skills to consistently and efficiently use:

  • The Four Question Framework
  • Data Flow Diagrams
  • The STRIDE mnemonic
  • Kill Chains


These techniques will enable participants to identify threats and mitigation techniques (such as controls and risk management), accurately document results, and turn threat analysis consistently and efficiently into more secure products. As a result, participants will eventually champion threat modeling within their organization.
