Security & Monitoring
strongest firewall in the world won’t help if someone hands over their login credentials to an attacker.
Have a plan for when things go wrong
No security system is perfect. Even the most well-defended organisations suffer breaches. What separates those that recover quickly from those that fl ounder is a solid incident response plan.
Automakers must prepare for worst-case scenarios - data breaches, ransomware attacks, and cyber threats that could compromise vehicle safety. The best approach is to create clear protocols for detecting, responding to, and containing threats before they escalate. This means setting up rapid- response teams, maintaining backups of critical systems, and ensuring that vehicles can be patched or taken offl ine if necessary.
Adopt global standards, not just
There’s no need for the automotive industry to create cybersecurity frameworks from scratch when international standards already exist. The NIST Cybersecurity Framework, ISO/SAE 21434, and GDPR data protection guidelines
provide comprehensive blueprints for securing connected systems.
Some automakers have been slow to adopt these standards, preferring to develop their own internal security measures. But as we’ve seen in other industries, this approach often leads to fragmented, inconsistent protections that create more vulnerabilities than they solve. Standardization across the industry will not only improve security but also streamline compliance with global regulations.
Transparency and user control build trust
Consumers care about privacy. The backlash against data-hungry tech companies has made it clear that people want to know what’s being collected about them and how it’s being used. Automakers that embrace transparency will have a competitive advantage.
While industry-wide security standards apply broadly to vehicle cybersecurity, when it comes to in-cabin vehicle services, consent management is the most critical element of data privacy. Unlike other forms of vehicle telemetry, in-cabin data directly impacts user privacy in a much more personal way. Automakers must prioritize clear, real-time
consent mechanisms that allow passengers to opt in or out of data collection at any moment. Simply burying consent agreements in terms of service is no longer acceptable; users must be given an intuitive, accessible way to control their own data in the cabin environment.
This level of control not only builds consumer trust but also ensures compliance with evolving privacy regulations. A vehicle needs to function much better than a smartphone in this regard because unlike phones, vehicles tend to be shared resources. Therefore, the ability to manage personal data of not only the owner, but also of anyone who is in the vehicle or anyone else who drives the vehicle, needs to be considered. Consequently, it’s even more important to offer a clear, transparent, and intuitive consent mechanism, making sure that people always know and can control what is happening with their data. Automakers that get this right will set themselves apart in an era where data privacy is becoming a key differentiator for consumers. This is the difference between offering better connected services with minimal liability risks, and bad services with maximum risks.
The bottom line: stick with what works
The auto industry doesn’t need to reinvent cybersecurity. The best practices are already out there - tested, refined, and proven effective by other sectors that have faced similar challenges. Automakers that embrace these lessons will be better equipped to protect their customers, their data, and their reputations. Instead of building one-off security solutions, the industry should leverage the decades of expertise developed in finance, healthcare, and IT. Strong access controls, regular updates, encryption, employee training, incident response planning, adherence to global standards, and transparent data policies aren’t just good ideas - they’re necessities.
Connected cars represent the future of mobility. If automakers want to secure that future, they need to learn from the past and stand on the shoulders of those who have already figured this out. Security isn’t a competitive differentiator; it’s a fundamental requirement. And the best way to get it right is to follow the blueprint that’s already been drawn.
