Threat modeling is often perceived as an intimidating exercise reserved for security experts. However, this perception is misleading. Threat modeling is designed to help envision a system or application from an attacker's perspective. Developers can also adopt this approach to design secure systems from the ground up. This article uses real-world implementation patterns to explore a practical threat model for a cloud monitoring system.What Is Threat Modeling?Shostack (2014) states that threat modeling is "a structured approach to identifying, evaluating, and mitigating risks to system security." Simply put, it requires developers and architects to visualize a system from an attacker’s perspective. Entry points, exit points, and system boundaries are evaluated to understand how they could be compromised. An effective threat model blends architectural precision with detective-like analysis. Threat modeling is not a one-time task but an ongoing process that evolves as systems change and new threats emerge.
