3 ways to test vehicle cyber security management systems
3 ways to test vehicle cyber security management systems .The future looks bright for connected and autonomous vehicles (CAVs) – in fact, analysts at McKinsey say that by 2030, 45% of new vehicles will be at SAE Level 3 or higher, with market shares of $ 450 billion to $ 750 billion. But as the market grows, the risk of cybercrime increases for new car technology. This is precisely the reason why governments and manufacturers are in the process of implementing regulations such as 2020 WP.29 regulations that require cybersecurity management systems. Over the next few years, manufacturers will need to ensure that their vehicle models meet the requirements for type-approval for cyber-security measures.
But what many tend to forget is that the implementation of cybersecurity management systems (CSMS) is not the end of the road. Testing is an important part of ensuring that CSMS fulfills its tasks. After all, there is really no point in implementing a system if you can not be sure that it works properly. Here are the tests that will help you ensure that CSMS really protects your vehicle and protects your car and its system from potential attacks. .
1) Scanning vulnerability
In all cybersecurity management systems, assessment and mitigation of any vulnerabilities is an important responsibility to ensure that the product operates at the maximum secure level. Vulnerability scanning is not a single check, but should be performed at each level of the product development process to enable maximum limitation and comprehensive analysis of additional threats. There are now two specific test analyzes that should be considered in vulnerability scanning, and both are equally important.
Static testing of software
Software static testing tests the source or object code without running it to find and eliminate errors or ambiguities. This is usually done in the early stages of development. This step is crucial as it can reveal major issues such as leakage, buffer overflows and deviations from standards. Because testing is done at an early stage, it can ward off increased development times and enable fewer problems to be found in later stages of development, which can often be much more expensive and time consuming to fix.
Software dynamic testing
Static testing counterpart, dynamic test testing with code execution to find weak areas in runtime environments and behavior of dynamic variables. The main goal of dynamic testing is to ensure that the system works properly without any defects. Because the codes are actually running, dynamic testing can take a little longer than static testing and can increase the cost of the final product as the shortcomings that exist will take more resources to mitigate. But dynamic testing will find the problems missed by static testing, usually finding more complex defects.
2) Fuzz Testing, or “Fuzzing”
The next step in testing is “fuzzing” or fuzz testing. Fuzz testing is basically providing “fuzz” or invalid or random data in the application or software to monitor crashes, potential memory leaks or incorrect code. Generating this invalid or random data is usually done through an automated program that generates fuzz.
Fuzzing can be useful because it adds a test element that cannot be generated by a human. However, there are limitations as it usually detects simple or basic threats, which means it must be combined with other testing techniques to ensure your security management system. Penetration testing
While fuzzing uses random or invalid data to test the system, penetration testing uses known cyberattacks or vulnerabilities to initiate simulated attacks, identify potential vulnerabilities, and select countermeasures to mitigate those vulnerabilities. Think of it as getting someone to act like a car thief to try to break into your car and gain access: through this “trick” to take over, the manufacturer can learn a lot about how they can better secure their vehicles’ access systems.
Through penetration testing
and to find flaws in the cybersecurity infrastructure, manufacturers can upgrade their security systems to address any flaws in the system. Testing is a big part of CSMS; Without a doubt, it is as important as the CSMS itself. But seen through the many different types of testing, there is no single test that ensures that a cybersecurity management system is completely foolproof. Since the technical development is constantly applied in a vehicle, the system must undergo several rounds and different types of tests to ensure that the risk is as minimal as possible.
If you work with a security solution provider to implement your CSMS, make sure they routinely test and work with you as a long-term client.

Before we look at C-ITS, let’s first look at what intelligent transport systems (ITS) are. These are the systems that collect and analyze data to improve the driving experience and to regulate traffic.
Examples of ITS include the modern GPS
the navigation system that provides drivers with real-time information on traffic levels, estimated travel times, traffic accidents, road constructions and even locations for traffic management cameras. Another interesting ITS is the left-hand drive sensor, which are sensors embedded in the ground to the left-hand drive field at intersections, so that the left-turn signal would only be switched on when needed.
C-ITS is simply more advanced ITS where vehicles and other road companies share their data to “collaborate” with each other on the road. Such collaboration is made possible by V2X (vehicle to all) technology, which enables vehicles to communicate directly with infrastructure (V2I), pedestrians (V2P) and the larger network (V2N).
In a previous blog article, we discussed in detail what V2X technology is and how it is used. To read that article, see: DSRC vs. C-V2X: A detailed comparison of the two types of V2X technology. Today we are here to look at seven of the most important features and benefits of C-ITS and how they paint the whole picture of autonomous driving. Collect driving data
All types of driving data – including location, speed, time and vehicle condition – are collected from vehicle on-board units. This data (when owners are approved) will be stored in a data center accessible to transport regulators and infrastructure developers to improve transport infrastructure and road safety. Sometimes car manufacturers (OEMs) also collect data about their cars to further improve their models with software updates and hardware enhancements.
Exchange traffic information in real time
When vehicles share their location and speed with each other, a massive transport network is formed consisting of real-time data. Each vehicle can then use the aggregated information on current traffic flows and even analyze them . to predict future traffic conditions over the next few hours. This means that all vehicles can choose an optimized route for their destination. which significantly reduces traffic. congestion and at the same time saves time and money spent in traffic.
Exchange real-time information on road risks
Traffic data is not sufficient to guarantee traffic safety. With C-ITS, vehicles receive information on a wide range of information on road conditions, including road surface temperature. humidity and the build-up of snow and rain from precipitation. Vehicles are also warned of curvy and sloping roads, road breaks and areas where traffic accidents often occur. Finally, information on emergency maintenance of roads and road works is shared with vehicles to ensure . That they are well informed about road risks and respond safely by reducing speed or detours.
