Threat Modeling for Digital Twins
o Real-time processing 5. ML models analyze processed data to flag anomalies( e. g. overheating engine): o Machine Learning o Digital Twin( DT) Model Repository o Data Analysis & Analytics
6. Fleet managers have access to dashboards and detailed information on separate vehicles using web interface / mobile applications: o Basic Visualization o Dashboards o Reporting
7. Fleet managers review alerts and approve automated maintenance requests: o Prescriptive Recommendations
8. Predictions trigger alerts in the user dashboard and maintenance systems. o Prediction o Alerts & Notifications
9. Maintenance schedules are pushed to third-party repair systems via APIs. o Enterprise System Integration o Collab Platform Integration o API Services
10. Post-repair data from service centers updates the digital twin, refining future predictions: o Digital Twin Integration
The analysis starts from the consideration of each capability as the asset. Then, if the capability is connected to other kinds of assets, more convenient for analysis, it may be replaced with that asset. For example, privacy( which is a capability considered as an asset) can be replaced with PII( as a data asset). Data-related capabilities can be replaced with the data they control or process. In some cases, an abstractly described capability( such as machine learning) can be replaced by a set of functions with a specific purpose( e. g. ML based anomaly detection for enhanced network security).
Various capabilities, representing the generic valuable functionality( like maintenance functionality), may be grouped together to form the asset. The main criteria for proper asset identification are the ability to connect the asset to possible damage in case of cyberattack or other kind of failure or disruption, to name and assess this damage. The empirical analysis of the damage kind( what can happen to the asset) is enough to validate the asset presence in the list. Example
By following these recommendations, we get this list of assets with connected damage kinds( Table 2-1).
