STRIDE: Threat Modeling Step by Step

Learn STRIDE threat modeling with DFDs, risk analysis, threat mitigation, security controls, and real-world examples

What you'll learn
- Apply the STRIDE framework to identify system threats.
- Build and analyze Data Flow Diagrams (DFDs) for threat modeling.
- Map threats to appropriate mitigations and controls.
- Use risk matrices and threat tables to prioritize security actions.

Requirements
- Basic cybersecurity experience required. Basic system or app knowledge is helpful.

Description
Understanding and mitigating security threats early in the design process is critical to building secure applications and systems. In this practical and hands-on course,“STRIDE: Threat Modeling Step by Step,”you will learn how to systematically identify, analyze, and mitigate threats using the STRIDE framework — one of the most widely used methodologies in application security.

This course is designed forsoftware engineers, security analysts, architects, and product managerswho want to embed security into the software development lifecycle. Whether you're securing cloud applications, microservices, mobile apps, or APIs, the step-by-step structure will help you master the fundamentals and apply them directly in your work.

You will start by learning the key concepts ofthreat modeling, why it matters, and where it fits into system design. Then, you’ll exploreData Flow Diagrams (DFDs)as the foundation for modeling how data moves through your system and where vulnerabilities may arise.

Each stage of the STRIDE model —Spoofing, Tampering, Repudiation, Information Disclosure, Denial of Service, and Elevation of Privilege— is covered in detail with real examples. You’ll learn how to map threats onto system components, assess their severity using risk matrices, and document them using threat tables. More importantly, you’ll discover how tomap each threat to appropriate security controls, whether preventive, detective, or corrective.

The course also teaches you how to track and reassess threats as your system evolves over time, enablingcontinuous securityand alignment with frameworks like OWASP, ISO/IEC 27001, and DevSecOps practices.

We use a realistic case study — a health tracking application — to demonstrate each concept, so you can see STRIDE in action from start to finish.

By the end of this course, you’ll be able to:

Create threat models from scratch using STRIDE

Build and interpret DFDs for your systems

Identify and prioritize security risks

Apply actionable mitigations

Collaborate confidently in threat modeling workshops

No prior experience in cybersecurity is required. Join now and gain the skills to secure your systems before attackers find the weaknesses.

Who this course is for:
- Software engineers, security analysts, architects, product managers, and anyone building or securing digital systems. Ideal for learners new to threat modeling.
