Threat modeling: As easy as OATMEAL

The OATMEAL threat modeling framework, developed to simplify and enhance the process of identifying and mitigating potential security threats, offers a structured and intuitive approach by breaking down complex environments into manageable layers. OATMEAL, an acronym for Overlays And Threat Modeling Events And Limitations, aims to demystify threat modeling by using overlays akin to map layers to visualize controls, detections, gaps, and potential attack scenarios. This method helps organizations understand their security posture and prioritize improvements by focusing on critical aspects like control gaps, detection gaps, and attack likelihood. Complementing the visual overlays, a detailed narrative document provides context and facilitates communication between technical and non-technical stakeholders, ensuring a comprehensive understanding of potential threats and recommended mitigations. By making threat modeling accessible to a broader audience, OATMEAL empowers organizations to enhance their security efforts effectively.
