Information Security in the Automotive Sector: Understanding the Value of VDA ISA and TISAX®
Table Of Contents:
In today’s digital world, information security is more important than ever before, and the automotive sector is no exception. As vehicles become more technologically advanced, they become more susceptible to cyber-attacks. This blog will explore the value of the VDA Information Security Assessment (ISA) and the Trusted Information Security Assessment Exchange (TISAX®) in the automotive sector and look at best practices for organisations looking to implement these standards.
The Automotive Risk Landscape
The automotive industry is undergoing rapid digital transformation, with connected and autonomous vehicles relying on advanced technologies such as the Internet of Things (IoT), artificial intelligence (AI), and 5G connectivity. This digital ‘renaissance’ has brought many benefits, but it also creates new security risks to address to ensure the safety and reliability of these digitally advanced vehicles.
One of the significant technological threats faced by the automotive sector is malicious attacks. With the increasing use of connected and autonomous vehicles, there is a growing risk that hackers may attempt to access PII stored in these vehicles, manipulate vehicle systems, or use vehicles as a launch pad for other attacks.
Another threat is the presence of counterfeit or low-quality components in vehicles. These components may contain security vulnerabilities that attackers can exploit, putting vehicles’ safety and reliability at risk. This could materialise physically, in the form of poor-quality metal fittings or wiring, or digitally, such as IoT devices that do not have the relevant safeguards and firewalls installed.
A real-world example of such a threat is the WannaCry ransomware attack in 2017, which affected several automotive manufacturers, and led to the discovery of counterfeit components in electric vehicles that contained security vulnerabilities.
Creating Cyber Secure Vehicles
To improve information security and reduce the risk of security incidents, many automotive suppliers undergo the VDA ISA and TISAX® assessments. But what are these standards, and what do they offer both automotive components and car manufacturers?
VDA Information Security Assessment (ISA)
VDA-ISA stands for “Information Security Assessment” in German “Informationssicherheits-Assessment”, and it is a standard for information security assessments developed by the German Association of the Automotive Industry (VDA).
The VDA ISA is a self-assessment questionnaire that covers various aspects of information security, including data protection, access control, and incident management. In true automotive spirit, there is even a focus on prototype protection at Assessment Level 3(AL3).
The VDA-ISA standard aims to help organisations within the automotive industry improve their information security posture by identifying and addressing potential vulnerabilities and risks. It provides a structured approach to assessing and enhancing information security, which can help organisations protect their sensitive data and intellectual property and maintain the trust of their customers and partners.
TISAX®– Trusted Information Security Assessment Exchange
TISAX® is a standard and framework for information security assessments developed under VDA (German Association of the Automotive Industry) guidance. Combining the ISA (Information Security Rules) of the VDA with ISO 27001’s Appendix A (technical controls) and several privacy requirements, TISAX® provides a standard set of guidelines for assessing and exchanging information security assessments among companies within the automotive industry.
TISAX® aims to meet the increasing demands for information security in the automotive sector, which increasingly relies on digital systems and networks. It provides a standardised approach to information security assessments, allowing companies to share assessment results with other supply chain organisations without additional checks.
The TISAX® framework covers a range of information security domains, including data protection, access control, incident management, and security management. The assessment process requires accredited and qualified third-party assessment providers (TSPs) to evaluate the security controls implemented by an organisation.
TISAX® assessments take a risk-based approach, meaning the assessment scope is tailored to an organisation’s specific risks. TISAX® assessments are carried out using standardised assessment methods and reporting templates, enabling organisations to compare their results with other organisations and identify improvement areas.
How TISAX® and VDA-ISA Are Improving Automotive Information Security
TISAX® and VDA-ISA provide a range of benefits for organisations within the automotive industry, including;
- Improved information security: TISAX® and VDA-ISA provide a structured and standardised approach to assessing and improving information security for organisations within the automotive industry. By undergoing assessments and implementing the necessary security controls, organisations can improve their security posture and reduce the risk of data breaches and cyber-attacks.
- Increased trust and credibility: TISAX® and VDA-ISA are recognised standards throughout the automotive industry and highlight a company’s commitment to information security. By complying with TISAX® or VDA-ISA, organisations can increase trust and credibility among their customers, partners, and suppliers.
- Simplified supply chain assessments: TISAX®and VDA-ISA provide a standard set of guidelines for assessing and exchanging information security assessments among companies within the automotive industry. This means that organisations can share assessment results with other organisations in the supply chain without additional evaluations.
- Competitive advantage: By complying with TISAX® and VDA-ISA standards, organisations can differentiate themselves from their competitors and demonstrate their commitment to information security.
- Compliance with legal and regulatory requirements: TISAX® and VDA-ISA assessments can help organisations within the automotive industry comply with legal and regulatory requirements related to information security. For example, the European Union’s General Data Protection Regulation (GDPR) requires organisations to implement appropriate security measures to protect personal data.
These assessments provide a standard and consistent way for automotive manufacturers to evaluate their information security and become aware of the protection their partners and suppliers hold. This helps ensure that associated companies have the necessary measures to protect sensitive information and reduce the risk of security incidents. Suppliers can demonstrate their commitment to information security and gain a competitive advantage in the automotive marketplace by undergoing these assessments.
Information Security Best Practices in the Automotive Sector
Implementing VDA ISA and TISAX® requires a comprehensive approach to information security. Organisations looking to comply with these standards must consider the following;
1. Risk assessment: Before starting the assessment process, it is essential to conduct a comprehensive risk assessment to identify potential security risks and vulnerabilities. This will help organisations prioritise their security efforts and focus on the most critical areas.
2. Incident response plan: Organisations should develop a comprehensive incident response plan that outlines the steps to be taken during a security incident. The plan should include procedures for reporting incidents, containing the damage and restoring normal operations.
3. Employee training: Employees play a critical role in maintaining information security, so it is crucial to provide regular training and awareness programs to educate employees about the importance of information security and their role in protecting sensitive information.
4. Implement security controls: Organisations should implement security controls based on industry standards such as ISO 27001. These standards provide a comprehensive set of security controls that can help organisations to meet the requirements of VDA ISA and TISAX®.
5. Regularly review and update security controls: Information security is an ongoing process. Reviewing and updating security controls to ensure they remain effective against evolving threats and risks is essential.
