Security experts, Chris Valasek and Charlie Miller, have developed an intrusion prevention device that will keep automobiles safe from cyber attacks.
The new device has been created with $150 worth of electronic parts along with a set of computer algorithms that can listen to traffic within the car's network to understand its working.
The security experts had demonstrated how to hack the Toyota Prius and Ford Escape at the 2013 Def Con hacking conference in Las Vegas.
The methods included ways to manipulate the breaks of the moving vehicles, which could lead to disastrous results.
The new device created by the team aims to help automobile makers defend their vehicles from security threats. It is capable of identifying traffic abnormalities, and can lock rogue activities.
Valasek told Reuters: "I really don't care if you hack my browser and steal my credit card. But crashing a car is life or death. It is dramatic. We wanted to be part of the solution."
The researchers raised concerns about the potential security threat to vehicles, but the US National Highway Traffic Safety Administration has dismissed any such fears, saying that it is yet to come across any incident of hacking of a vehicles control system.
