Cybersecurity Practices in Automotive

In the contemporary landscape of the automotive industry, cybersecurity has transitioned from a theoretical consideration to a critical operational requirement. This evolution is primarily attributable to recent legislative enactments mandating enhanced security measures for vehicular systems, specifically targeting the resilience of Electronic Control Units (ECUs) against cyber threats. This legislative backdrop necessitates that Original Equipment Manufacturers (OEMs) adopt rigorous cybersecurity protocols to safeguard vehicular functionalities and sensitive data.

The advent of autonomous vehicles amplifies the significance of cybersecurity. In these systems, a cyber breach could potentially enable remote manipulation of vehicular controls, presenting a substantial risk to passenger safety. Therefore, OEMs must develop robust cybersecurity strategies not only to protect vehicle integrity but also to maintain their market reputation.

To fortify ECUs against cyber threats, our approach at JSD leverages compliance with the ISO 21434 standard, reinforced by adherence to CSMS R.155 and SUMS R.156 regulations. Our methodology is rooted in advanced software development practices, incorporating the ASPICE framework, which includes:

SEC.1 – Cybersecurity Requirements Elicitation: This phase involves the comprehensive identification and documentation of cybersecurity requirements, ensuring a foundational understanding of the security needs.

SEC.2 – Cybersecurity Implementation: Here, we implement the identified cybersecurity measures, employing state-of-the-art technologies and methodologies to build a resilient system.

SEC.3 – Risk Treatment Verification: This step involves the verification of implemented cybersecurity measures against identified risks, ensuring that the solutions effectively mitigate potential threats.

SEC.4 – Risk Treatment Validation: In this final phase, we validate the efficacy of the cybersecurity solutions in real-world scenarios, ensuring robustness and reliability.

Our expertise encompasses a range of cybersecurity activities, including Asset Identification, Threat and Risk Assessment (TARA), and the establishment of System Cybersecurity Requirements. Each process is subjected to rigorous testing protocols to maximize security.

A key element of automotive cybersecurity is the execution of TARA, which assesses the severity and feasibility of potential cyberattacks. We focus on protecting core attributes such as Confidentiality, Integrity, Authenticity, and Availability. TARA involves the evaluation of threats like Spoofing, Tampering, Repudiation, Information Disclosure, Denial of Service, and Elevation of Privilege, considering their impact across Safety, Financial, Operational, and Privacy domains.

At JSD Solutions, our experience in the automotive sector extends to the development of sophisticated cybersecurity solutions, including Hardware Security Modules (HSM), Crypto Stack integration in AUTOSAR, implementation of Secure Boot mechanisms, Secure Onboard Communication, Vehicle Key Management Systems, Vehicle Diagnostic Protection, and Secure Storage solutions.
