Gesture recognition and haptic feedback are also increasingly common. The state-of-the-art displays of today include curved OLED displays, 3D digital clusters, head-up displays, and highly advanced voice recognition systems. Augmented reality features are on the horizon as cockpits transform into sophisticated information hubs.

The vehicle cockpit has undergone rapid innovation, moving from simple analogue gauges to today's highly digital, customisable, and multimodal human-machine interfaces. This evolution mirrors the transformative shift towards an automotive digital cockpit, where connectivity and autonomy advancements converge to create even more intelligent and driver-focused environments.

Cybersecurity Threat Landscape for Vehicle Cockpit Systems

The cybersecurity threat landscape for vehicle cockpit systems is vast and rapidly evolving. Some of the major types of threats include:

Data Theft and Privacy Breaches

With cockpit systems gathering vast amounts of data about vehicle performance, location tracking, and even driver behaviour, breaches pose major privacy risks. Hackers or malicious insiders may attempt to steal driver data and location history, or corporate trade secrets related to proprietary algorithms and technology.

System Disruption

Attackers may attempt to overwhelm cockpit systems and networks through distributed denial of service (DDoS) attacks, brute force login attempts, and other techniques aimed at disrupting connectivity and availability. System outages could have major safety implications depending on what functions are impacted.

Financial Fraud

As cockpit systems enable greater integration with digital wallets, payment apps, and e-commerce, they open up new avenues for financial fraud through hacking of accounts, skimming of payment info, or identity theft leveraging stored customer data.

Reputational Damage

All of the above threats, if exploited, could also severely damage an automaker's brand reputation and public trust if they are seen as having lax security standards and failing to protect customer safety and privacy.

To mitigate these threats, automakers must implement robust cybersecurity best practices across their entire product lifecycle. The stakes for getting security right will only grow as cockpit systems become more interconnected and critical to vehicle functionality.

Importance of Robust Cybersecurity in Advanced Vehicle Systems

Modern vehicles contain increasingly sophisticated infotainment and advanced driver assistance systems that are connected to various networks. This connectivity exposes vehicles to cybersecurity risks that can have major financial and safety implications if not properly addressed.

Financial Impacts of Breaches

A cyber attack that gains access to critical vehicle systems can be extremely costly for auto manufacturers. Remediating security vulnerabilities across an entire fleet of vehicles is a complex and expensive undertaking. The harm to a brand's reputation from a major breach can also dramatically impact sales and revenue. The financial fallout from large-scale vehicle hacking could run into the billions of dollars in lost sales, lawsuits, and recovery costs.

Safety Risks

The most alarming consequence of poor automotive cybersecurity is the potential safety risks. If hackers can remotely access critical systems like acceleration, braking, or steering, they could cause crashes and threaten lives. One study found that a remote attack could result in as many as 9,000 fatalities if deployed across a fleet of vehicles.

Robust cybersecurity protocols that safeguard financial systems and critical safety features are therefore essential. The risks of lax security are too steep, both in terms of potential financial losses and lives endangered. Automakers must treat cyber threats with the gravity they deserve and continuously strengthen their defenses.

Key Components of Vehicle Cockpits

Modern vehicle cockpits contain advanced electronics and software that control critical systems and allow for increasing levels of automation. Key components vulnerable to cyber threats include:

  • Infotainment system - Provides entertainment and information to passengers through touchscreens, voice commands, and smartphone integration. An entry point for attackers to access other systems.
  • Instrument cluster - Displays critical information like speed, fuel level, and engine diagnostics. It could be compromised to show false readings.
  • Powertrain - Engine, transmission, throttle - hackers demonstrated the ability to remotely control acceleration and braking.
  • Body control - Centralized control of lights, locks, HVAC - vulnerabilities could enable external control.
  • Internal network - MOST, CAN, Ethernet - they interconnect electronic control units (ECUs). Vulnerable to attacks that spread malware.

Advanced Vehicular Cockpits

With more wireless connectivity and automation, the attack surface is increasing. A holistic approach is needed to secure vehicle cockpits against cyber threats.

Current Cybersecurity Measures in the Industry

Ensuring the security of vehicle cockpit systems is crucial due to their exposure to sensitive customer data and connection to various networks, making them susceptible to cyber threats. Automakers have implemented a range of cybersecurity measures to safeguard these systems.

One key strategy involves employing secure bootloaders and encrypted firmware updates. This helps prevent malware infections and tampering by verifying the integrity of firmware before allowing it to load. 

Another layer of protection involves secure key storage mechanisms, such as hardware security modules, to safeguard cryptographic keys. These keys, especially those used for communication authentication, are fortified against extraction. Software integrity checking, employing cryptographic hash verification, helps detect tampering or code modifications and digitally signed firmware updates further ensure authenticity.

Sensitive data is encrypted both at rest and in transit using standards like TLS, VPNs, HTTPS, and SSL/TLS certificates. Additional security measures include multi-factor authentication, least privilege principles, and firewalls, which allow only authorised access to cockpit systems and data. Identity and access management solutions centralise control, enhancing overall security.
