Uhkamallinnus, often translated as threat modeling, is a structured process used in cybersecurity to identify potential threats, vulnerabilities, and countermeasures to protect systems, applications, and data. It involves systematically analyzing what could go wrong and what steps can be taken to prevent or mitigate those risks.

The core idea behind threat modeling is to proactively think like an attacker. By understanding an attacker's potential motives, methods, and targets, organizations can better defend themselves. This process typically begins by defining the system or application to be analyzed, its assets, and its boundaries. Subsequently, potential threats are brainstormed, often categorized using frameworks like STRIDE (Spoofing, Tampering, Repudiation, Information Disclosure, Denial of Service, Elevation of Privilege).

Once threats are identified, vulnerabilities that could be exploited are pinpointed. This might involve reviewing code, system configurations, or architectural designs. Following the identification of threats and vulnerabilities, appropriate countermeasures are proposed and implemented. These countermeasures can range from technical solutions like encryption and access controls to procedural ones like security training and incident response plans.

Threat modeling is not a one-time activity but rather an ongoing process that should be revisited as systems evolve, new threats emerge, and organizational requirements change. It helps prioritize security efforts, allocate resources effectively, and build more resilient systems from the ground up. Various methodologies and tools exist to support threat modeling, catering to different types of systems and organizational needs.
