How to Reduce Risk in Connected Automotive Operations

The Rise of Connected Vehicles and Cybersecurity Risks

The 2020s have become a decade defined by automation and connectivity, and nowhere is this more evident than in the automotive industry. Modern drivers are increasingly relying on “smart” vehicles powered by connected systems that enhance safety, convenience, and entertainment.

Vehicles connected to the Internet of Things (IoT) can provide real-time traffic updates, predictive maintenance alerts, and early warnings about potential safety hazards. These features are not just useful—they are in high demand. In fact, the IoT vehicle market in the United States is expected to grow at a compound annual growth rate (CAGR) of over 8% through 2030.

Despite these benefits, automotive manufacturers and suppliers must recognize the growing risks that come with advanced technology. As IoT, automation, and artificial intelligence become more deeply integrated into vehicles, cyber threats are also becoming more advanced. This creates new opportunities for hacking, system manipulation, and data theft.

Understanding Risk in Connected Automotive Systems

Because connected vehicles rely on near-constant internet access, they are exposed to ongoing cyber risks. Malicious actors can exploit these connections to gain unauthorized access to vehicle systems.

The risks associated with automotive IoT range from personal data theft to serious physical safety threats. In one well-known case, researchers successfully hacked a connected Jeep and gained control of its dashboard systems, including braking—an incident that resulted in a large-scale vehicle recall by Chrysler.

Responsibility for vehicle cybersecurity lies with both manufacturers and drivers. Vehicles must be designed with strong security measures to ensure they are safe to connect and operate. Key risks facing connected automotive systems include:

• Theft of personal and financial data (such as stored payment information)
• Unauthorized control of onboard systems
• False sensor readings or signal manipulation
• Tampering with diagnostics and system settings
• Loss of control over steering, braking, or other safety-critical functions

These risks highlight the need for cybersecurity to be embedded directly into automotive safety planning. Failure to do so can lead not only to physical danger but also to regulatory penalties and reputational damage, especially if payment data is mishandled or PCI compliance is ignored.

Identifying Cybersecurity Threats in the Automotive Industry

One major challenge in automotive IoT security is the lack of standardized security frameworks. As a result, connected ecosystems often suffer from inconsistent protection levels. While a universal framework may emerge in the future, vigilance is currently the best defense.

Automotive professionals should remain alert to the following potential vulnerabilities:

• Software weaknesses or coding errors
• Security gaps in third-party vendors or suppliers
• Excessive or unnecessary data storage
• Physical access risks to in-vehicle systems
• IoT features that add risk without providing real value

Working with cybersecurity experts who conduct penetration testing and routine system scans is one of the most effective ways to identify threats early. Once vulnerabilities are discovered, they can often be resolved through timely software updates and patches.

Building a Framework to Reduce Cyber Risk

Preventing cyber threats is far more effective than responding to them after damage occurs. Although no universal IoT security framework exists, manufacturers can still adopt strong protective strategies.

Key principles for a risk-reduction framework include:

• Understanding likely hacker motivations and securing vulnerable access points
• Minimizing human error through rigorous code reviews and testing
• Encrypting all stored and transmitted data using industry standards
• Limiting data storage to only what is strictly necessary
• Enabling regular, easy-to-install software and firmware updates
• Eliminating unnecessary or insecure device connections
• Maintaining strong internal cybersecurity to prevent breaches during development
• Ensuring physical security of hardware and source code
• Carefully vetting all third-party vendors for security compliance
• Integrating cybersecurity into overall vehicle safety testing and planning

The manufacturing sector is particularly vulnerable to cyberattacks, making internal security practices just as critical as customer-facing protections.

Preparing for Future Automotive Cybersecurity Challenges

Connected vehicles will continue to be attractive targets for cybercriminals. Ongoing vigilance, regular security assessments, and collaboration with cybersecurity specialists are essential for long-term protection.

Automotive companies should also develop clear incident response plans to address vulnerabilities quickly and effectively. Following PCI DSS standards for protecting sensitive data provides a strong foundation against attacks.

Ultimately, a proactive approach—focused on prevention, rapid response, and continuous improvement—offers the best defense. By giving cyber threats no opportunity to take hold, manufacturers can protect both their customers and their brand reputation.
