Best Practices To Achieve Vehicle Cybersecurity

Safety is always put first when it comes to driving. To keep drivers and passengers safe, cybersecurity has grown in importance with the increased usage of technology in automobiles. Hackers can access a vehicle’s systems and inflict damage or steal confidential data. Because of this, it’s critical that automakers and suppliers put best practices for attaining vehicle cybersecurity into action.

There are a variety of ways that attackers can take advantage of weaknesses in the software and hardware of your car, from remote hacking to physical attacks on keyless entry devices. You can find vulnerabilities in your system before they can be exploited by using secure coding practices, routine threat modelling, and vulnerability management assessments.

Working with other automakers and suppliers can also make sharing knowledge about emerging dangers or vulnerabilities easier, allowing everyone to keep on top of the latest developments in vehicle cybersecurity.

Understanding the Risks of Vehicle Cyber Attacks

To keep yourself and your passengers safe on the road, it’s important to recognize the hazards of vehicle cyber-attacks if you think your automobile can’t be hacked. Modern cars are becoming increasingly connected, which gives hackers additional opportunities to target weak spots in their computer systems. 

These assaults can involve everything from collecting private information from the vehicle’s infotainment system to seizing control of crucial driving features like the brakes and steering.

The ability of vehicle cyber-attacks to go unnoticed for extended periods is one of their biggest threats. Unlike typical physical theft, a hacker who gains access to an automobile’s systems may not instantly make their presence known when a stolen car can be easily identified as gone. 

Implementing Secure Coding Practices

You may significantly lower the risk of cyber assaults on automobiles by implementing safe coding techniques in compliance with ISO 21434. Writing code that is secure against malicious assaults and weaknesses is known as secure coding. This means that engineers must write code with security in mind during the whole development process.

Regular code reviews and vulnerability testing are two ways to achieve secure coding practices. Developers can stop attackers from later exploiting such flaws by spotting them early. To continually enhance their security measures, developers must keep up with new threats and best practices. By prioritizing secure coding techniques, you can ensure customers’ car software is as secure as possible.

Conducting Threat Modeling and Vulnerability Management

Regular threat modelling and vulnerability management are vital steps in guaranteeing the security of your vehicle software. Vulnerability management entails locating and addressing any potential weaknesses, whereas threat modelling aids in identifying potential security risks to your system. You can proactively address security vulnerabilities before they turn into significant issues by including these practices in your software development life cycle.

The first step in conducting efficient threat modelling is to recognize every element of your system and comprehend how each interacts with the others. After that, consider the many dangers that could affect each component and how they might spread throughout the system. 

Afterward, you can create plans for reducing those risks using secure coding techniques or other techniques like network segmentation or access controls. You may stay ahead of changing security concerns by routinely analyzing and updating your threat models, which will protect your car software from online threats.

Collaboration and Information Sharing among Automakers and Suppliers

Modern car safety depends on collaboration and information exchange between automakers and suppliers. Given the complexity of automotive systems nowadays, relying exclusively on internal expertise is insufficient.

Working with other industry players might give you a wider view of potential threats and weaknesses. By learning from one another’s failures and experiences, automakers can share information and lessen the need for duplication of effort.

This cooperation can occur in various ways, such as joining sector-wide working groups or exchanging best practices at forums or conferences. Together, manufacturers and suppliers can build a more secure connected vehicle ecosystem that better safeguards consumers from online dangers.

Ensuring Security Throughout the Vehicle Lifecycle

To protect contemporary automobiles against cyber-attacks, security must be maintained throughout the vehicle lifecycle. This entails putting cybersecurity precautions in place throughout the vehicle’s whole life, from design and development to production, delivery, and maintenance. To accomplish this, suppliers and automakers must cooperate.

Numerous areas require attention, including safeguarding the software code while it is being developed and guaranteeing secure communication protocols in the car’s network systems. One method to find potential vulnerabilities in hardware and software components and examine potential hazards provided by third-party suppliers is to conduct frequent risk assessments throughout the vehicle lifecycle.

Regularly applying patches and upgrades to hardware and software can help reduce any possible risks that can develop over time. Automakers may better safeguard the security of their customers while also maintaining the reputation of their brands by giving cybersecurity a high priority throughout the whole lifespan of a car.


Congratulations! The ideal procedures for achieving vehicle cybersecurity have been taught to you. You should be aware that cyber attacks can seriously jeopardise your driving safety. To protect the security of their vehicles, automakers, and suppliers must employ safe coding practices, perform threat modeling, and monitor vulnerabilities. 

Achieving vehicle cybersecurity also requires cooperation and information exchange across all stakeholders involved in the production of cars. Finally, retaining knowledge of potential vulnerabilities and updating software often to ensure security throughout the vehicle lifecycle is critical. By adhering to these recommended practices, we can all work together to ensure everyone’s roads are safer.
