Automotive Network Security

End-to-End Security Solutions for Vehicle Network Systems

Driven by advancements in automation and connectivity, in-vehicle communication networks are now more vulnerable to cyber threats than ever before.

Focused on securing modern vehicle architectures and communication systems, Diconium’s network security solutions help OEMs and Tier-1 suppliers achieve embedded compatibility and meet regulatory requirements.

Providing end-to-end protection across CAN, LIN, and automotive Ethernet networks, our solution addresses the unique real-time demands and resource constraints of automotive and embedded environments, ensuring compliance with ISO/SAE 21434 and UNECE WP.29.

This is How We Work

Our process begins with a focused assessment of embedded or automotive network architecture, identifying key vulnerabilities, compliance requirements, and communication protocols like CAN, LIN, or Ethernet.

Next, we apply industry-leading practices in secure system design, integrating components such as IDS/IPS, encrypted tunnels, ACLs, and network segmentation with precision. Each solution is developed to ensure scalability, tailored to the resource constraints of embedded systems and the complex topologies of in-vehicle networks.

Post-deployment, we enable continuous monitoring and compliance updates, supported by secure logging and audit-ready documentation.

Benefits of Adopting Our Network Security Solutions

Modern vehicles operate within a distributed ecosystem of ECUs, communication buses, and connected services all of which demand robust, purpose-built protection. Our solutions are engineered to address both current threats and evolving vulnerabilities across automotive and embedded networks.

Why Network Security Matters for In-Vehicle Embedded Systems?

In recent times, automotive vehicles and embedded systems have turned into highly connected, software-defined machines that heavily rely on communication networks spanning CAN, LIN, automotive Ethernet, and V2X technologies.

Nevertheless, a single vulnerability within these network systems can expose critical systems such as braking, steering, or powertrain control to malicious interference. Moreover, embedded components, especially Electronic Control Units (ECUs), are particularly vulnerable due to their real-time constraints and limited resources.

Network security solutions leverage advanced security mechanisms including encryption, intrusion detection systems (IDS), and firewalls that help OEMs and Tier-1 suppliers to defend against cyber intrusions, safeguard data confidentiality , enable secure diagnostics, over-the-air (OTA) updates, and remote functionality.

FAQ

What is automotive network security?

Automotive network security protects in-vehicle communication systems like CAN, LIN, and Ethernet from unauthorized access, data manipulation, and cyberattacks. It ensures safety, compliance, and system integrity in connected vehicles.

Why do modern vehicles require specialized network security solutions?

Modern vehicles are complex and software-defined machines with multiple interconnected systems. Moreover, as connectivity continues to increases through V2X, OTA updates, and telematics so do attack surfaces. Specialized network security ensures the integrity, confidentiality, and availability of these systems while meeting evolving cybersecurity regulations.

What types of threats can IDS/IPS detect and prevent in vehicle networks?

IDS/IPS solutions generally detect anomalies, unauthorized access attempts, protocol violations, and malicious communication patterns within in-vehicle networks, enabling real-time threat mitigation.

How does Diconium’s solution secure communication in embedded automotive systems?

Our network security solution secures data in transit using SSL/TLS, IPsec, and VPN protocols. Combined with network segmentation, ACLs, and IDS/IPS, the solution ensures authenticated, encrypted communication across ECUs and embedded platforms.

What types of threats does automotive network security defend against?

Our solution protects vehicle network systems against multiple cyber threats including unauthorized access, data exfiltration, ECU spoofing, man-in-the-middle attacks, denial of service (DoS), malware injection, and OTA update exploitation.

How does Diconium’s solution support ISO/SAE 21434 and WP.29 compliance?

Our solution implements intrusion detection, encryption, and access controls aligned with ISO/SAE 21434 and UNECE WP.29, supporting audit readiness and homologation.
