Description

Elevate your software security expertise with our comprehensive guide to threat modeling. This course empowers you to proactively identify and mitigate security risks throughout the software development lifecycle, using Microsoft's industry-standard STRIDE framework and Data Flow Diagrams (DFDs).

Designed for software engineers, security analysts, architects, DevOps professionals, and product managers, this practical course teaches you to build robust, secure systems. You'll learn to visualize your system architecture with DFDs, apply the STRIDE methodology (Spoofing, Tampering, Repudiation, Information Disclosure, Denial of Service, and Elevation of Privilege) to pinpoint vulnerabilities, and prioritize threats using a risk-based approach. We'll explore real-world scenarios through a compelling case study, a fictional health tracking application, to ground your learning in practical application.

Through step-by-step instruction, you will:

Master the art of creating accurate and informative Data Flow Diagrams.
Thoroughly analyze each component of your system for potential threats using STRIDE.
Implement a robust risk assessment and prioritization methodology using a comprehensive risk matrix.
Effectively map identified threats to specific security controls and develop actionable mitigation strategies.
Establish a system for consistently monitoring your system for changes that might impact your threat profile.

This course is ideal whether you're a seasoned developer or just starting your journey into application security. We provide all necessary templates and examples, ensuring you're well-equipped to conduct effective threat modeling workshops and communicate risk effectively to both technical and non-technical stakeholders. Learn to build secure software from the ground up. Enroll now and take control of your application's security.

Curriculum

Introduction

This introductory section sets the stage for the course. The "Introduction" lecture provides a comprehensive overview of the course content and learning objectives, laying a solid foundation for the subsequent modules. It will establish the importance of proactive threat modeling and its relevance across various software development stages.

STRIDE Threat Modeling Step 1 & 2

This section delves into the fundamentals of threat modeling. "Step 1 - Understand Threat Modeling Fundamentals" establishes a solid understanding of core concepts and methodologies. This will be followed by "Step 2 - Learn the STRIDE Framework", which provides a detailed explanation of the STRIDE threat categorization model: Spoofing, Tampering, Repudiation, Information Disclosure, Denial of Service, and Elevation of Privilege, explaining each threat type in detail and illustrating how they apply in real-world scenarios.

Step 3 - Build a System Model Using DFDs

This module focuses on practical application by teaching how to build Data Flow Diagrams (DFDs). "Step 3 - Build a System Model Using DFDs (1)" and "Step 3 - Build a System Model Using DFDs (2)" provide a comprehensive guide to creating effective DFDs, covering the essential components, techniques for visual representation, and best practices for modeling complex systems.

Step 4 - Identify Threats with STRIDE

This section combines previous lessons to practically apply the STRIDE framework to identify threats within a system model. "Step 4 - Identify Threats with STRIDE" uses real-world examples to demonstrate the practical application of the STRIDE framework, step-by-step, to detect security vulnerabilities in a system modeled with DFDs.

Step 5 - Analyze and Prioritize Threats

This section introduces risk assessment and prioritization. "Step 5 - Analyze and Prioritize Threats (1)" and "Step 5 - Analyze and Prioritize Threats (2)" covers methods for assessing identified threats based on their likelihood and impact, enabling effective prioritization and resource allocation for mitigation efforts.

Step 6 - Map STRIDE Threats to Security Controls

This module explores mitigation strategies. "Step 6 - Map STRIDE Threats to Security Controls (1)" and "Step 6 - Map STRIDE Threats to Security Controls (2)" show you how to map identified threats to appropriate security controls and document mitigation strategies, creating actionable plans to reduce vulnerabilities and improve system security.

Step 7 - Monitor System Changes That Affect Threats

This section emphasizes ongoing security. "Step 7 - Monitor System Changes That Affect Threats (1)" and "Step 7 - Monitor System Changes That Affect Threats (2)" teaches the importance of continuous monitoring and how to incorporate threat modeling into the software development lifecycle for long-term security management.

Conclusion

The concluding section summarizes key takeaways and provides guidance for continued learning and practical application of threat modeling techniques learned in the course. The "Conclusion" lecture reinforces core concepts, highlights practical applications, and provides resources for further study and professional development.
