Original Abstract Submitted

various approaches are disclosed for protecting vehicle buses from cyber-attacks. disclosed approaches provide for an embedded system having a hypervisor that provides a virtualized environment supporting any number of guest oses. the virtualized environment may include a security engine on an internal communication channel between the guest os and an external vehicle bus of a vehicle to analyze network traffic to protect the guest os from other guest oses or other network components, and to protect those network components from the guest os. each guest os may have its own security engine customized for the guest os to account for what is typical or expected traffic for the guest os (e.g., using machine learning, anomaly detection, etc.). also disclosed are approaches for corrupting a message being transmitted on a vehicle bus to prevent devices from acting on the message
