ISO 21434 Automotive Cybersecurity Standards

Explore ISO 21434, the standard for cybersecurity in motor vehicles, outlining lifecycle risk management for electrical and electronic systems, plus organizational cybersecurity management, supplier coordination, and validation and threat analysis.

Explore ISO 21434's organizational cybersecurity management, governance, culture, and information sharing, and learn how to implement policies, resources, and audits across interdepartmental processes.

Assign cybersecurity responsibilities across the project, assess security relevance, tailor activities, and formalize a cybersecurity plan within the project plan, including work products, configuration management, reuse, and off-the-shelf component assessment.

Explore distributed cybersecurity activities under ISO 21434, including supplier capability, RFQ requirements, and alignment of responsibilities. Also cover the cybersecurity interface agreement (CIA), responsibility assignment matrix, milestones, and vulnerability management.

Define continual cybersecurity activities by monitoring sources for cybersecurity information, triaging and evaluating events to identify weaknesses and vulnerabilities, and applying remediation and incident response guided by risk treatment decisions.

Define item scope, boundaries, functions, and preliminary architecture, specify the item's operational environment and interfaces, and set cybersecurity goals via asset identification and threat-based risk analysis with verification and controls.

Explore ISO 21434 product development: design cybersecurity specifications from higher architectural levels, allocate requirements to components, and ensure secure modeling, verification, and testing across the software development lifecycle.

Learn to validate automotive cybersecurity at the vehicle level and the production configuration, ensure goals align with threat scenarios, and justify validation activities and operational environment requirements.

Explore the production phase under ISO 21434, detailing a production control plan with cybersecurity requirements, steps for post development, tool selection, integrity protection, and validation for implementation.

Define and implement the cybersecurity incident response process, establish a remedial action communication plan, assign responsibilities, record new cybersecurity information, and set progress criteria and actions for closure.

Define the end of cybersecurity support and decommissioning process, including a customer communication procedure and an interface agreement between supplier and OEM that specifies decommissioning requirements for development.

Analyze threat scenarios and risk assessment in automotive cybersecurity by identifying assets with cyber properties, damage scenarios, and impact categories, mapping attack paths and feasibility, and selecting risk treatment options.

Explain how to build an automotive cybersecurity culture under ISO 21434 by detailing overall and project-dependent management, policy rules and processes, awareness, audits, and project work products.

Implement continuous cybersecurity activities to monitor the product in the field, assess events, perform vulnerability analysis, manage vulnerabilities, and triage cybersecurity information.

Explore the ISO 21434 concept development phase by identifying assets, mapping threat scenarios, rating impacts, analyzing attack paths and feasibility, and making risk determinations and treatment decisions.

Explore the product development phase of automotive cybersecurity, including refining requirements and architecture, integrating and verifying software components, specifying software development needs, and validating cybersecurity at the vehicle level.

Learn about the post development phase, covering production, cybersecurity incident response, updates, and secure decommissioning of artifacts. Understand distributed cybersecurity activities and the cybersecurity interface agreement for inter-company collaboration.

Explore examples of cybersecurity culture in automotive projects aligned with ISO 21434, emphasizing traceability of cybersecurity decisions, balanced cost and schedule, timely resource allocation, and unbiased third party audits.

Learn to define distributed cybersecurity responsibilities with a cybersecurity interface template, detailing who is responsible, approves, supports, informs, and consults, plus document references and confidentiality levels.

Apply a question-driven algorithm to determine cybersecurity relevance for a project, assessing e technology use, interfaces, operation, wireless sensors, user data processing, and network components to decide ISO 21434 relevance.

Explain how cybersecurity assurance level (cal) defines levels of risk and assurance for assets, using a pictorial view from concept to decommissioning, and provide a common language for assurance requirements.

Map verification and validation to the v-model, perform configuration and integration for secure operation, and verify cybersecurity requirements while managing vulnerabilities.

Explore how ISO 21434 clauses interact across concept, production, and post development phases, mapping requirements to assets, threat scenarios, risk treatment, vulnerability analysis, and monitoring.

Explain the rating criteria for safety, financial, operational, and privacy impacts, detailing severity levels from severe to negligible and their effects on injuries, finances, vehicle function, and PII.

Determine attack feasibility by evaluating visibility levels and criteria, from high, medium, low, to very low, and apply a time-frame based attack potential approach with four time-frame categories.

Explore a practical ISO 21434 use case for a head lamp system across an OEM and supplier. Examine concept and product development phases, cybersecurity goals, statements, integration and verification.

Explore the concept phase of a headlamp control use case within ISO 21434, defining items, boundaries, threats, and cybersecurity goals to manage risk.

Refine gateway cybersecurity requirements in the product development phase and apply a white-list control, then assess vulnerabilities via penetration testing and attack feasibility.
