A walk through a real embedded penetration test, step by step.
Threat intelligence for vehicles is easy to buy and hard to use. A feed of thousands of CVEs and advisories is only valuable once it becomes a short list of things your team should actually do.
The goal is not more data; it is decisions. A continuous monitoring capability watches connected vehicles for threats and coordinates the response, but it can only act on intelligence that has been filtered down to your assets and ranked by real risk.
What counts as useful intelligence
Relevant threat intel is tied to what you actually ship: the components in your SBOM/HBOM, the protocols your ECUs speak, the platforms and libraries you depend on, and the active exploits and campaigns targeting them. A vulnerability in a library you don't use is noise; one in a library that runs on your telematics unit is a work item.
From feed to decision
- Match. Correlate incoming advisories against your component inventory so only things you run surface.
- Score. Rank by exploitability and vehicle impact, not raw CVSS alone.
- Route. Send each item to an owner with a clear action, patch, mitigate, or accept and document.
Feeding the Monitoring Loop
Connect that triaged stream to your monitoring and incident-response processes so intelligence drives detection rules and field response, and so you can show, as UN R155/R156 expects, that you watch for threats after a vehicle is on the road.
If you're standing up monitoring from scratch, a gap assessment is a practical first step.
