Automotive Cybersecurity - From Compliance to Production

Modern vehicles are software-defined platforms with 70-100 ECUs, millions of lines of embedded code, and connectivity across cellular, Wi-Fi, V2X, and cloud services. This creates a complex attack surface that regulators worldwide have mandated must be managed through a formal Cybersecurity Management System (CSMS). ISECURION helps automotive organizations build, implement, and maintain CSMS frameworks aligned with ISO 21434, AIS 189, AIS 190, TISAX, UNECE R155, and R156 - covering the full vehicle lifecycle from concept to decommissioning.

The Regulatory Challenge

India's AIS 189 and AIS 190 are becoming mandatory for vehicle type approval. Globally, UNECE R155 and R156 are required for access to EU, Japanese, and Korean markets. ISO 21434 and TISAX are demanded by OEMs from their entire supply chain. Non-compliance means blocked market access and lost contracts.

ISECURION's Approach

We deliver structured, evidence-based automotive cybersecurity consulting - from gap assessments and TARA through CSMS policy development, secure SDLC integration, automotive penetration testing, and homologation documentation - in a single integrated engagement aligned to both Indian and global frameworks.

Dual Framework Efficiency

Since AIS 189 aligns with ISO 21434 and UNECE R155, and AIS 190 aligns with R156, our engagements are designed to satisfy both Indian and global requirements simultaneously - avoiding duplication of effort and reducing time-to-compliance for organizations targeting multiple markets.

FAQs

Frequently Asked Questions

ISO/SAE 21434 is the international standard for automotive cybersecurity engineering. It defines processes for managing cybersecurity risks across the vehicle lifecycle - from concept through decommissioning. It forms the technical foundation for AIS 189 compliance in India and UNECE R155 compliance in global markets, and is increasingly demanded by OEMs from their entire supply chain.

AIS 189 defines Cybersecurity Management System (CSMS) requirements for vehicles in India, covering governance, TARA, secure development, vulnerability monitoring, and incident response. AIS 190 establishes a Software Update Management System (SUMS) for secure OTA updates. Both are becoming mandatory for vehicle homologation (type approval) in India and align with UNECE R155 and R156 respectively.

Compliance is required for automotive OEMs seeking type approval, Tier-1 and Tier-2 suppliers providing ECUs, software, and hardware components, EV manufacturers, automotive software companies, connected vehicle platform providers, ADAS and autonomous vehicle technology firms, and engineering service companies working with global OEMs who require TISAX or ISO 21434 alignment from their supply chain.

TISAX (Trusted Information Security Assessment Exchange) is an information security assessment framework for the automotive supply chain, ensuring secure handling of confidential OEM data, prototype information, and intellectual property. Global OEMs including European manufacturers require Tier-1 suppliers, engineering service providers, and software development partners in India to achieve TISAX compliance before sharing sensitive product information or receiving contracts.

TARA (Threat Analysis and Risk Assessment) is a structured methodology required by ISO 21434 and AIS 189 to identify, evaluate, and prioritize cybersecurity risks affecting vehicle systems and communication interfaces. It involves identifying assets, damage scenarios, threat scenarios, attack paths, and risk ratings - forming the basis for defining cybersecurity goals and selecting appropriate security controls for vehicle systems.

Timelines vary by organization maturity and scope. Typically a gap assessment takes 2-4 weeks. TARA execution requires 3-6 weeks depending on vehicle system complexity. CSMS framework development takes 6-12 weeks. Full compliance readiness including secure SDLC integration, penetration testing, and homologation documentation preparation typically requires 3-6 months for a complete program.

Yes. ISECURION conducts comprehensive automotive penetration testing covering ECUs and embedded systems, infotainment and telematics units, CAN bus and in-vehicle network security, V2X communication interfaces, mobile companion applications, OTA update mechanisms, and cloud backend infrastructure supporting connected vehicle services - with findings structured for type approval documentation.

UNECE R155 requires vehicle manufacturers to implement a CSMS managing cybersecurity risks across the vehicle lifecycle - mandatory for type approval in UNECE member markets including the EU, Japan, and South Korea. Without R155 compliance vehicles cannot be sold in these markets. UNECE R156 requires a Software Update Management System (SUMS) with secure OTA update controls, version traceability, and integrity validation - closely mirrored by India's AIS 190.

Yes. Since AIS 189 aligns with ISO 21434 and UNECE R155, and AIS 190 aligns with UNECE R156, ISECURION designs engagements to satisfy both Indian and global requirements in a single integrated program - avoiding duplication of effort, reducing overall compliance cost, and accelerating time-to-approval for organizations targeting both domestic and international automotive markets.

ISECURION serves automotive clients across all major automotive manufacturing and R&D hubs in India including Bangalore (automotive R&D, EV startups), Pune (OEMs and Tier-1 suppliers), Chennai (the "Detroit of India"), Hyderabad (automotive software and embedded systems), Delhi NCR (OEM headquarters and regulatory bodies), Mumbai (corporate headquarters), and Ahmedabad (emerging EV manufacturing hub).
