Vehicle security changes with every software release, supplier patch, vulnerability disclosure, and fleet mile. Static assessments quickly become obsolete. This presentation introduces a living, dynamic risk assessment approach that continuously integrates threat intelligence, vulnerability disclosures, and incident signals. Likelihoods are recalibrated as soon as real events occur—whether in a company’s own fleet or observed across peers—transforming assumptions into evidence-based probabilities and refreshed attack-path priorities. The result is sharper risk focus, faster validation cycles, and audit-ready continuous compliance throughout the vehicle lifecycle. By treating SBOM components as assets, linking supply-chain data, connecting XDR for SEVs and incidents, and using simulation to refine response, cybersecurity becomes a daily process that strengthens resilience and trust across the vehicle lifecycle
