Application of the Threat Modeling Method In an Operating System

Due to the increase in professionals adopting the home office model due to the COVID-19 pandemic, the threat to company information and assets has become more evident. This work aims to identify, describe and evaluate the impacts of applying the threat modeling method, using risk management standards, on corporate computers with the aid of a monitoring system. The proposed method for application suggests the adoption of processes and a system for updating, controlling and managing the Windows Operating System to reduce the threats faced. The research identified security using the STRIDE and DREAD methods and the ISO and NIST security standards. It verified 14 types of threats found in an operating system that can be properly identified and mitigated with the threat exploitation method
