How to Secure Your Vehicle Cockpit Systems from Cyber Attacks

Home | Blog | How to Secure Your Vehicle Cockpit Systems from Cyber Attacks

Vehicle cockpit systems are no longer just simple dashboards. They now offer a range of features such as navigation, entertainment, and vehicle performance monitoring systems. These features make driving more convenient and enjoyable, but they also expose the cockpit systems to cybersecurity risks. Hackers could potentially access the cockpit systems and compromise the safety and functionality of the vehicle.

This article explains how cockpit systems have changed over time, what cybersecurity threats they face, and how to implement effective cybersecurity measures. It aims to provide useful information so industry stakeholders can make smart choices to enhance cyber resilience. Secure cockpit systems will be crucial for building consumer confidence and enabling future vehicle innovations.

The Remarkable Evolution of Vehicle Cockpit Systems

The evolution of vehicle cockpits from analogue gauges in the 1980s to today’s highly advanced digital interfaces has been remarkable. In the 1980s, cockpits were dominated by analog gauges and switches, controlling functions like HVAC and audio with dials and buttons.

Moving into the 1990s, digital displays began to appear, albeit limited to basic functions such as trip mileage and radio information. The 2000s brought advanced driver assistance systems (ADAS), leading to an increase in digital displays for warnings like lane departures and blind spots.

By the 2010s, fully digital instrument clusters became mainstream, offering customisable displays of drivetrain data. Today, large touch screens are central, integrating entertainment, navigation, and ADAS, often with gesture recognition and haptic feedback. Advanced features like curved OLED displays and augmented reality are pushing cockpits to become complex information hubs.

This rapid innovation reflects a shift towards digital automotive cockpits, where connectivity and autonomy converge to create intelligent and driver-centric environments.

Understanding the Cybersecurity Challenges for Vehicle Cockpit Systems

Vehicle cockpit systems face a dynamic and expansive cybersecurity threat landscape, featuring the following key challenges:

Data Theft and Privacy Concerns: Cockpit systems store extensive data, including vehicle performance, location tracking, and driver behavior. This data is a prime target for hackers aiming to steal driver information, location history, or proprietary trade secrets.

System Disruption Potential: Malicious actors may use tactics like DDoS attacks and brute force login attempts to overwhelm cockpit systems, disrupting connectivity and posing safety risks due to potential system outages.

Financial Fraud Risks: Integration with digital wallets and payment platforms exposes cockpit systems to financial threats, including account hacking, payment information skimming, and identity theft through the exploitation of stored customer data.

Reputational Damage: Exploiting these threats poses a substantial risk to a vehicle’s brand and public trust. If there is a perception that security measures are not sufficient, it may result in a failure to ensure the safety and privacy of customers.

To counter these threats, it’s crucial for automakers to implement robust cybersecurity best practices throughout their entire product lifecycle. As cockpit systems become more interconnected and critical to vehicle functionality, the importance of getting security right will only increase.

Cybersecurity Challenges and Solutions for Modern Vehicle Systems

Modern vehicle systems offer a variety of features that enhance the driving experience, such as infotainment and advanced driver assistance systems. However, these features also rely on connectivity to various networks, which exposes them to cyberattacks. Cyberattacks can have serious financial and safety consequences if not prevented or mitigated.

Financial Consequences of Cyberattacks

A cyberattack that targets critical vehicle systems can have a huge financial impact on auto manufacturers. Fixing security flaws across a large number of vehicles is a difficult and costly process. A major breach can also damage a brand’s reputation and affect its sales and revenue. The financial losses from widespread vehicle hacking could reach billions of dollars in lost sales, lawsuits, and recovery costs.

Safety Consequences of Cyberattacks

The most dangerous outcome of poor automotive cybersecurity is the potential safety risks. If hackers can remotely control critical systems like acceleration, braking, or steering, they could cause accidents and endanger lives. One study estimated that a remote attack could cause up to 9,000 deaths if applied to a fleet of vehicles.

Robust cybersecurity protocols that protect financial systems and critical safety features are therefore vital. The stakes of weak security are too high, both in terms of potential financial losses and lives at risk. Automakers must take cyber threats seriously and constantly improve their defences.

Understanding the Crucial Elements of Vehicle Cockpits

Today’s vehicle cockpits are equipped with advanced electronics and software that govern vital systems and facilitate increasing levels of automation. Here are the key components that are susceptible to cyber threats:

Infotainment System – This system delivers entertainment and information to passengers via touchscreens, voice commands, and smartphone integration. It can be an entry point for attackers to infiltrate other systems.

Instrument Cluster – This component displays essential information such as speed, fuel level, and engine diagnostics. If compromised, it could display incorrect readings.

Powertrain – Comprising the engine, transmission, and throttle, this component has been shown to be vulnerable to remote control of acceleration and braking by hackers.

Body Control – This is the centralised control of lights, locks, and HVAC. Any vulnerabilities could allow for external control. Internal Network – Networks like MOST, CAN, and Ethernet interconnect electronic control units (ECUs) and are susceptible to attacks that disseminate malware.

How Modern Vehicle Systems Stay Secure from Cyber Attacks?

Modern vehicle systems have many features that rely on connectivity, such as infotainment and advanced driver assistance systems. However, this also makes them vulnerable to cyberattacks. Automakers and suppliers are working hard to develop new technologies and methods to enhance cyber protection.

Some of the key technologies include:

Intrusion detection and prevention systems (IDPS) – Tools that monitor network activity and stop cyberattacks as they happen. IDPS is becoming a common feature in vehicles to keep in-vehicle networks safe all the time.

Over-the-air (OTA) updates – Enabling cyber security patches and firmware updates to be sent remotely to vehicles. This makes sure the fleet is secure from new vulnerabilities. AI-powered cybersecurity – Using artificial intelligence and machine learning to spot anomalies and new attack patterns. AI can react quickly to new threats.

Formal verification – Using maths to check the accuracy of critical software code. Helps remove vulnerabilities in software design.

Vulnerability testing and penetration testing – Testing by ethical hackers to find weaknesses in systems before cars are sold. Fixing vulnerabilities before production. With the fast growth of smart connectivity, automakers are increasing their R&D in cybersecurity. Having multiple layers of protection and constantly improving their systems will be important to keep ahead of threats.
