This presentation from STRONGER 2023 explored a tech stack that leverages virtual and augmented reality capabilities to create a Cyber Digital Twin (CDT). The CDT goes beyond the traditional Digital Twin concept by incorporating cybersecurity into virtual models. This enables a proactive approach to cybersecurity, where potential vulnerabilities can be identified and addressed in the virtual environment before their exploitation in the physical world. The combination of virtual reality and cyber technologies allows the exploration of several use cases like threat simulation, risk assessment, incident response training, non-invasive red team assessment, etc. Security teams can identify mission-critical assets and virtualize key components for attack path and business impact analysis. Moreover, the virtual nature of CDT facilitates an aggressive re-testing schedule to manage active attack surfaces. As more and more industries adopt virtual reality technologies, CDTs are expected to become an essential part of the digital transformation journey.
