Why is threat modeling important?

Threat modeling is a crucial practice in cybersecurity as it systematically identifies potential threats, vulnerabilities, and attack vectors concerning a system or application. By understanding these threats, organizations can develop appropriate mitigations and defensive strategies tailored to their specific risks. This proactive approach enables teams to prioritize security measures based on the likelihood and potential impact of identified threats.

In contrast, focusing solely on IT infrastructure or limiting the relevance of threat modeling to large organizations neglects the comprehensive nature of this practice, which applies across various environments and scales. Additionally, viewing threat modeling as a one-time assessment overlooks its dynamic nature; threats and vulnerabilities evolve, making continuous reassessment vital for maintaining security posture.
