Automotive cybersecurity is the practice of protecting vehicle systems, electronic control units (ECUs), and in-vehicle networks from unauthorized access, data breaches, and cyberattacks that could impact safety, performance, or privacy.
Automotive cybersecurity goes beyond traditional information security. It bridges compliance requirements such as ISO 21434 (road-vehicle cybersecurity engineering), ISO 27001 (information security), and GDPR (data privacy). Together, these frameworks ensure that both vehicle systems and customer data remain secure across the entire product lifecycle.
We at Embitel, have delivered multiple automotive projects with cybersecurity at their core. So, we know where to put the plug! Automotive cybersecurity is all-pervasive, hardware, software, network, and cloud; we help you secure each one of them. From building secure bootloaders and Transport layer security to Trusted Applications for automotive cybersecurity and Public Key Infrastructure (PKI) services , we implement cybersecurity in all its forms.

ISO/SAE 21434 is a comprehensive standard that outlines the requirements for cybersecurity risk management in the design and production of automotive systems. This standard is essential for OEMs and Tier-1 suppliers as it guides the integration of cybersecurity measures across the vehicle's lifecycle.
It emphasizes the development of a robust cybersecurity management system, systematic risk assessment through TARA, and integrating security into the product development lifecycle.
The standard also focuses on efficient incident response, industry collaboration for knowledge sharing, and stringent documentation practices. Essentially, it ensures that automotive products are secure and compliant in an era of increasing cyber threats.
Ans. ISO 21434 standard has recently been published. However, our cybersecurity team has been closely following the various stages that the standard has gone through. Hence, we have a fair understanding of the standard.
We have been delivering cybersecurity related projects before the release of ISO 21434 standard, primarily based on its draft version. Since, the standard is now published, we follow the automotive cybersecurity guidelines as prescribed in the standard for all cybersecurity related projects.
Ans. Yes, we can make your existing automotive solution compliant to automotive cybersecurity. The process requires gap analysis and an assessment of existing cybersecurity measures. After the gap analysis, we will lay down the requirements and make changes in the solution. The changes might affect the entire system architecture, introduce new validation and verification methods and more depending on various factors.
Ans. Diagnosing a vehicle remotely has emerged as a convenient for the customer as well as the service center. But it also opens up a potential threat of unauthorized access to the vehicle function. We have a ready-to-deploy DoIP protocol software that enables remote ECU diagnostics. It is made secure by the Transport Layer Security module (TLS module) among other features such as Secure Socket Layer (SSL) and IP security.
Ans. We have delivered FOTA solution to our customers with security features as required by the projects’ specifications.
Let’s look at all security features implemented:
Ans. We equip our Secure Bootloader solution with AES-128, CRC32, HMS Drivers, Digital Signature and Secondary Bootloader (SBL) features. These components make sure that that the data transmission between ECUs is completely secure.

Ans- Yes, we develop Trusted Applications for automotive cybersecurity use cases. Some of our delivered projects include development of hard/soft OTP TA, blade authentication, cryptographic services etc. We work closely with Tier-1s and OEMs to tailor each TA to their SoC, operating system, and security requirements.
Ans- We’ve delivered the following types of Trusted Applications to customers:
Ans- Automotive industry has adopted ISO26262 as a de-facto standard for making the vehicles safe. This standard has already been practiced in the industry by both OEM and suppliers for vehicle homologation and component development. ISO26262 addresses to limit or eliminate the unintended system behavior that can lead to safety issues. However, this does not address the intentional manipulation of the system by an external entity that could potentially compromise the safety of vehicle, its users and the road occupiers. Hence the security and safety go hand in hand in the modern connected vehicles. ISO 21434 is the standard that guides automotive cybersecurity.
Modern connected vehicles need to be as secure as they are safe. In many aspects, security will be directly responsible for safety of the vehicle. Hence, there is a need for cybersecurity and functional safety to work in tandem.
As cars transform into complex software system with numerous connected ECUs, they become more vulnerable to cyber-attacks. This necessitates a shift in vehicle architecture towards a secure-by-design approach.
What are the cybersecurity risks associated with charging system for electric vehicles? Are there enough preventive measures in place to mitigate these risks?
As vehicles transform into highly connected, software-driven machines, protecting them from cyber threats has become paramount.
Automotive cybersecurity is all about protecting the vehicle electronic components from unauthorized access and control. Growing degree of connectivity in vehicles creates avenues for amazing features. However, connectivity to external entities also makes the systems vulnerable to cyber-attacks. Automotive cybersecurity is a set of measures that can identify and thwart such attacks and keep the vehicle occupants safe.
Cybersecurity for road vehicles has been standardized in ISO 21434 standard. This standard defines the engineering requirements for managing the risks associated with cybersecurity. Right from the concept phase to component decommissioning, the standard has a framework for cybersecurity processes.
Automotive cybersecurity makes sure that the data transmitted to and from the vehicle ECU is delivered unchanged and to the intended party. To achieve this, three important aspects are controlled- Authenticity, Integrity, and Confidentiality.
Authenticity of the data implies that the data has been exchanged in a trustworthy manner and has been delivered to the intended receiver.
Integrity of the data means that the data has not been tampered with and the content is delivered unchanged and complete.
Confidentiality entails that there is encryption algorithm securing the data and to prevent it from being accessed and read by unauthorized recipient.
