Cyber security standards for automotive applications are a set of guidelines and requirements designed to protect vehicles from cyber threats. These standards are used to protect the integrity of vehicle data, communication systems, and the safety of passengers.

The main purpose of these standards is to protect the confidentiality, availability, and integrity of automotive systems and networks. They ensure that all communication between the vehicle and its components, as well as between the vehicle and external systems, is secure and protected from malicious attacks.

Examples of cyber security standards for automotive applications include ISO/SAE 21434, which defines requirements for secure and safe development of automotive systems, and ISO/SAE 21434-2, which provides guidance for the security of in-vehicle networks.

The standards also define requirements for authentication and authorization, data encryption, intrusion detection and prevention, secure communications protocols, and secure software updates. They also include requirements for hardware and software security, as well as for secure communication between the vehicle and external systems.

These standards help to ensure the safety of passengers and the security of vehicle data, and they are updated regularly to keep up with the latest threats. Automotive manufacturers, suppliers, and security experts must be aware of these standards in order to ensure the security of their vehicles.

1. Secure Software Development Process: Automotive manufacturers should establish secure software development processes for the creation of vehicle systems and software. This process should involve the use of secure coding practices, security testing, and assurance activities to ensure that the code meets security and safety standards.

2. Secure Communications: Automotive manufacturers should implement secure communication protocols, such as TLS/SSL, to ensure that data and commands sent over the vehicle’s electronic control networks are encrypted and authenticated.

3. Secure Data Storage: Automotive manufacturers should ensure that data stored on the vehicle’s systems and components is encrypted and properly secured.

4. Secure Over-the-Air Updates: Automotive manufacturers should deploy secure over-the-air (OTA) update processes to ensure that only authorized updates are installed on the vehicle’s systems and components.

5. Secure Authentication: Automotive manufacturers should deploy secure authentication protocols, such as two-factor authentication, to ensure that only authorized users can access the vehicle’s systems and components.

6. Security Monitoring: Automotive manufacturers should implement security monitoring processes to detect, investigate, and respond to security events and incidents.

7. Security Awareness: Automotive manufacturers should provide security awareness training to employees and other stakeholders to ensure that they understand the importance of cyber security and how to respond to security events and incidents.
