What is Threat Modeling and Why Should You Care?

Imagine building a house. You wouldn’t just start laying bricks without a blueprint, right? You’d plan for strong foundations, secure doors and windows, and a robust roof to protect against the elements. Threat modeling is essentially the security blueprint for your software, system, or application. It’s a structured approach to:

1. Identify Potential Threats: What could go wrong? Who might attack your system, and how?
2. Understand Vulnerabilities: Where are the weaknesses in your design that attackers could exploit?
3. Devise Countermeasures: How can you strengthen your system to prevent or mitigate these threats?

By doing this early in the development lifecycle, you can save significant time, effort, and money compared to fixing security flaws after deployment.
