Compared to classic models, modern vehicles feature highly connected systems and are software-intensive and complex. Embedded microcontrollers, numbering around 70 to 100, are responsible for executing millions of lines of code. Safety-critical applications such as steering, engine control, braking, airbag functions, and navigation systems fall under the control of these electronic control units (ECUs). As cars become more interactive, they become increasingly vulnerable to attacks from hackers as they connect to the internet, as well as with other vehicles (V2V) and infrastructure (V2X). Let’s see how to guarantee connected vehicle security.

Types of attacks on smart cars

A modern vehicle can be hacked either by physical access or through remote access of the In-Vehicle Network. Direct physical access to the internal network is possible through OBD ports, debug ports, or digital multimedia ports. Remote attacks on the car can be carried out using various vectors, such as CD/DVD players, short-range wireless access-Such as Bluetooth, RFID (remote keyless entry, vehicle immobilizers, tire pressure monitoring systems), dedicated short-range communications, and long-range wireless access, including Wi-Fi, and cellular technologies such as LTE, GSM, and CDMA. Considering how important smart car cybersecurity is and how many threats there are, it is important to take care of the security of car systems.

How to protect smart cars?

Protecting cars should be a priority for every owner. This means that you must protect automotive systems and car data transmission from external threats. It is possible to achieve this.

To safeguard connected vehicles from cyber-attacks, the automotive system must implement fitting security controls that utilize software and hardware cryptography. This security system must ensure the safety of data both in transit, in existence, and being accessed. It should also be able to detect unapproved and unplanned modifications. Remote access can be made more secure and reduce the risk of identity theft and unauthorized disclosures by implementing multi-factor authentication. All of these requirements can be met through a combination of technical enhancements.

#1 Keep your software up to date

Ensuring software is updated is important. Automakers regularly issue car software updates to patch security vulnerabilities, which should be installed promptly.

#2 Use a VPN when using your car’s Wi-Fi

When using Wi-Fi in your vehicle, be sure to use a VPN. If you have a router in your car, then you should set up VPN on the router to protect all devices. All devices connected to the Internet should install VPN protection. One reliable solution is VeePN, although there are other providers.

#3 Use a strong password or PIN

Ensure robust security for your car’s infotainment system by using a strong password or PIN. Avoid simple passwords like “123456” or “password” and opt for longer, more complex passwords that are difficult to guess.

#4 Install only trusted apps

In today’s technology-driven world, it seems like there’s an app for everything. Even cars are now equipped with infotainment systems that allow drivers to access apps on the go. However, it’s important to be cautious about what apps you install on your car’s infotainment system. Installing apps from untrusted sources can put your safety and privacy at risk. That’s why it’s recommended to only download apps from trusted sources, such as the official app store for your car’s manufacturer. By doing so, you can ensure that the apps you install are secure and won’t compromise your personal information while you’re on the road.

#5 Perform regular security checks on the service

Car theft is a common problem that many car owners across the globe face. It can be devastating to have your vehicle stolen, especially if it’s an expensive one. One way to ensure that your car is safe from theft is to have its security system checked regularly by a qualified mechanic. This is important because it helps identify any security vulnerabilities that may exist, allowing for immediate fixing. Regular security checks are crucial in safeguarding your car and giving you peace of mind. Plus, don’t forget that prevention is always better than cure. So, if you want to keep your car secure, make it a point to schedule regular security checks with a trusted mechanic.

#6 Don’t connect your car to public Wi-Fi networks

Protect your data – avoid connecting your car to public Wi-Fi networks. These networks lack proper security measures, making it an easy target for hackers to intercept your information. Stay safe and steer clear of public Wi-Fi networks.

#7 Keep up to date with cybersecurity news

Stay informed about the newest hacking dangers and safeguard your vehicle from potential attacks. Stay ahead of the curve by remaining informed about the latest threats and taking preventative measures to protect your car.


Smart car security is an important topic that needs to be addressed. By following these tips, you can ensure your vehicle remains secure and protected from potential threats. Stay informed about the latest cybersecurity news and take proactive steps to protect your vehicle data. Additionally, be sure to keep up with software upgrades as they become available to patch any vulnerabilities in the system.
