Master STRIDE Threat Modeling: Hack-Proof Your Apps

Master STRIDE Threat Modeling: Hack-Proof Your Apps with Case Studies

This course provides real-world case studies, hands-on threat modeling techniques, and actionable mitigation strategies to secure your applications against modern threats.

1. What is STRIDE?

In this section, we will explore the STRIDE threat modeling framework, a powerful methodology used to identify and categorize security threats in software systems. STRIDE stands for:

· Spoofing – Impersonating a user or system to gain unauthorized access.

· Tampering – Unauthorized modification of data or code.

· Repudiation – Denying an action while avoiding accountability.

· Information Disclosure – Unintended exposure of sensitive data.

· Denial of Service (DoS) – Disrupting service availability for legitimate users.

· Elevation of Privilege – Gaining higher-level permissions illegally.

You will learn how these threats manifest, their impact on systems, and foundational strategies to mitigate them.

2. Key Steps in Threat Modeling

Threat modeling is a structured approach to identifying and mitigating security risks. In this module, we will break down the four key steps of effective threat modeling:

1. Understand the System – Mapping architecture, data flows, and trust boundaries.

2. Identify Potential Threats – Using frameworks like STRIDE to uncover vulnerabilities.

3. Assess and Prioritize Risks – Evaluating threat severity and likelihood.

4. Implement Countermeasures – Designing security controls to mitigate risks.

By the end, you will be able to systematically analyze threats and apply risk-based security measures.

Case Study 01 - Spoofing Attack Via Fake Login

In this case study, we examine a real-world spoofing attack on a banking application, where an attacker impersonates a legitimate user to gain unauthorized access. We will cover:

· Attack Scenario – How the spoofing attack was executed.

· STRIDE Analysis – Breaking down the threat using the STRIDE model.

· Mitigation Strategies – Authentication hardening, multi-factor authentication (MFA), and monitoring.

· Lessons Learned – Key takeaways for securing identity mechanisms.

· How to Protect Your Application – Best practices to prevent spoofing.

Case Study 02 - Tampering Attack Ecommerce Price Manipulation

This case study explores tampering in an e-commerce system, where attackers manipulate prices or transaction details. We will analyze:

· Attack Scenario – How price tampering was achieved.

· STRIDE Analysis – Identifying tampering risks in the system.

· Mitigation Strategies – Input validation, cryptographic checks, and audit logs.

· Lessons Learned – Ensuring data integrity in transactions.

· How to Protect Your Application – Different strategies and controls to protect your application.

Case Study 03 -Repudiation Attack Disputed Financial Transaction

Here, we investigate a repudiation attack, where a user denies performing a financial transaction. Topics include:

· Attack Scenario – How repudiation was exploited.

· STRIDE Analysis – Evaluating non-repudiation failures.

· Mitigation Strategies – Digital signatures, audit trails, and logging.

· Lessons Learned – Ensuring accountability in transactions.

· How to Protect Your Application – Implementing non-repudiation controls.

Case Study 04 - Hospital Patient Records Disclosure

This case study examines an information disclosure breach in a healthcare system, exposing sensitive patient data. We will cover:

· Attack Scenario – How the data leak occurred.

· STRIDE Analysis – Assessing information exposure risks.

· Mitigation Strategies – Encryption, access controls, and data masking.

· Lessons Learned – Protecting confidential data.

· How to Protect Your Application – Secure data handling practices.

Case Study 05 - Privilege Escalation Attack

We dissect a privilege escalation attack, where an attacker gains admin rights illegitimately. Key topics:

· Attack Scenario – Exploiting weak permission checks.

· STRIDE Analysis – Identifying elevation of privilege risks.

· Mitigation Strategies – Least privilege principle, role-based access control (RBAC).

· Lessons Learned – Securing authorization mechanisms.

· How to Protect Your Application – Preventing unauthorized access.

Threat Modeling with Microsoft Threat Modeling Tool

In this hands-on module, you will learn to use the Microsoft Threat Modeling Tool to:

· Create a Threat Model – Diagramming system components and data flows.

· Perform STRIDE Analysis – Identifying threats using the framework.

· Generate Reports (HTML/CSV) – Documenting and sharing findings.

· Update Threat Models – Keeping models current with each release.

By the end, you will be able to integrate threat modeling into your development lifecycle effectively.
