Connected-car cyber risk: what it means for automotive security teams

TL;DR: Connected cars sit at the centre of a growing automotive data ecosystem, where rising monetisation, regulatory complexity, vulnerabilities and cyberattacks are forcing the industry to balance innovation with cybersecurity protection, according to VicOne. The governance challenge is no longer abstract: data flows, connected services and safety exposure now need joint control.

Key questions

Q: What should automotive security teams do first when connected-car data exposure is unclear?

A: Start with a data-flow and dependency inventory.

Q: Why do connected vehicles create greater cyber risk for fleet operators than isolated systems?

A: Connected vehicles expand risk because every wireless interface becomes a possible entry point, including Bluetooth, Wi Fi, cellular links, radio systems, tire pressure monitoring, and even compromised media.

Q: What are the signs that automotive cyber governance is too fragmented?

A: Look for duplicated risk registers, inconsistent supplier reviews, unclear ownership of vehicle data, and security decisions made separately by engineering, privacy and compliance teams.

Practitioner guidance

• Inventory connected-car data flows Build a complete map of where vehicle data originates, where it is stored, who can consume it and which third parties receive it.
• Align cyber risk and compliance ownership Create a shared governance model across security, legal, privacy and engineering so that regulatory obligations, incident response and supplier risk are reviewed together rather than in separate workstreams.
• Treat new connected features as risk changes Require security review before enabling new data services, telematics integrations or partner-facing capabilities, because every added connection changes the exposure profile of the vehicle ecosystem.

Bottom line: Connected-car security now depends on governing the automotive data ecosystem, not just hardening individual vehicles.
