TISAX vs ISO 27001: Which Do Automotive Suppliers Need?

Introduction

Step 1: Open your ICT provider register. If you don't have one, that's your first problem. Assessing whether your automotive supplier organization needs TISAX or ISO 27001 compliance is a critical decision that impacts your operations, reputation, and financial well-being. In the next 10 minutes, take stock of your current security certifications and understand the implications of not having the appropriate one.

The European financial sector is no stranger to stringent regulatory frameworks. In the automotive industry, suppliers are also increasingly held to high standards of security in their information and communication technology (ICT). Confusion often arises between TISAX (Trusted Information Security Assessment Exchange) and ISO 27001 (International Organization for Standardization's Information Security Management System), both of which are designed to ensure robust security practices. The stakes are high, with potential fines up to €30 million or 6% of global annual turnover per GDPR infringement, operational disruptions, and irreparable reputation damage.

By diving deep into the core differences, benefits, and requirements of TISAX and ISO 27001, this article provides a clear roadmap for automotive suppliers to navigate the complex landscape of ICT security compliance. Read on to ensure your organization is not just compliant but also competitive in this rapidly evolving market.

The Core Problem

Beyond the surface-level description of TISAX and ISO 27001, the real costs of non-compliance or choosing the wrong certification can be staggering. Consider a mid-sized automotive supplier with an annual turnover of €500 million. A GDPR-related fine could amount to a crippling €30 million—or 6% of their annual revenue. Additionally, the time wasted on rectifying audit failures or operational disruptions can equate to millions in lost productivity and opportunities.

What most organizations get wrong is assuming that ISO 27001 is sufficient for all industries. While ISO 27001 provides a comprehensive framework for information security management, TISAX is tailored specifically for the automotive sector and its unique security challenges. A 2021 report by the European Network and Information Security Agency (ENISA) emphasized the need for sector-specific security measures, particularly in industries like automotive where the risk of cyber-attacks can have severe real-world consequences.

ENISA's guidelines on sector-specific information sharing reference Article 71 of the NIS Directive, which underscores the importance of exchanging good practices, risk management experiences, and enhancing cooperation among industry stakeholders. TISAX, endorsed by the European Union as the standard for the automotive industry, aligns with this directive and is specifically designed to manage the risks associated with the interconnected and digitized nature of modern vehicles.

Conversely, an ISO 27001 certification might leave gaps in compliance for automotive suppliers. For instance, ISO 27001 does not address the specific risks posed by vehicular communication systems or the vulnerabilities in advanced driver-assistance systems (ADAS). A study by the University of Twente found that 100% of the tested ADAS were susceptible to cyber-attacks, which could lead to life-threatening situations. This underscored the necessity for a sector-specific approach like TISAX to address these unique challenges.

Why This Is Urgent Now

Recent regulatory changes have heightened the urgency for automotive suppliers to reassess their security certifications. The enforcement of GDPR and the upcoming NIS 2 Directive are pushing for stricter security measures. Moreover, the European Commission's proposal for a cybersecurity certificate scheme under the European Certificate for the Internet of Things (IoT) Act highlights the growing demand for robust security standards.

Market pressure is also mounting as major automotive manufacturers and their customers demand TISAX certification as a condition for doing business. This is evident in the Volkswagen Group's requirement for all suppliers to achieve TISAX certification by 2022, illustrating the competitive disadvantage faced by non-compliant suppliers who risk losing business opportunities.

The gap between where most organizations are and where they need to be is significant. A survey by Capgemini found that 59% of automotive companies reported they were unprepared for the rise in cyber-attacks, highlighting a pressing need for sector-specific security measures. The urgency is further amplified by the increasing sophistication of cyber threats targeting the automotive industry, as evidenced by incidents like the 2020 ransomware attack on Honda, which resulted in a temporary halt of production and significant financial losses.

In conclusion, understanding the nuances between TISAX and ISO 27001 is not just a compliance issue, but a strategic imperative for automotive suppliers. The next part of this article will delve into the specific requirements and benefits of each certification, providing actionable insights for your organization to make an informed decision.

The Solution Framework

Navigating the complex requirements of TISAX and ISO 27001 can seem daunting, but a step-by-step approach can simplify the process. Begin by understanding the core differences. TISAX focuses on security assessments and information exchange within the automotive industry, while ISO 27001 is a more generalized framework for managing information security risks.

Step 1: Analyze Your Supply Chain Obligations

Identify the specific requirements imposed on your organization by your clients and the relevant industry consortiums. Consult the contractual agreements to clarify whether ISO 27001, TISAX, or both are necessary. If unclear, reach out to your clients for clarification.

Step 2: Conduct a Gap Analysis

Compare your current information security management systems against the requirements of both TISAX and ISO 27001. Your goal is to identify gaps and determine where improvements are needed. For TISAX, the ENX Exchange can provide a list of TISAX requirements.

Step 3: Implement Security Controls

Based on the gap analysis, implement necessary security controls. For ISO 27001, these include asset management, access control, and business continuity planning. For TISAX, focus on network security, data protection, and secure communication processes. Ensure documentation processes are robust to prove compliance.

Step 4: Conduct Internal Audits

Regularly conduct internal audits to assess compliance with both standards. This is essential in maintaining best practices and identifying issues before external audits.

Step 5: Obtain Certification

Seek external certification for both standards if required. For ISO 27001, an accredited certification body will conduct audits. For TISAX, the certification is performed by an accredited assessment center.

Actionable Implementation Details:

• Conduct regular risk assessments as per ISO 27001 Annex A and TISAX ALR (Automotive Light Requirements).
• Implement a systematic approach to information security management as outlined in ISO 27001, section 4.1.
• Use the TISAX ALR as a checklist for assessing protection against threats and vulnerabilities.

What "Good" Looks Like vs. "Just Passing":

"Good" compliance goes beyond obtaining a certification; it involves integrating security best practices into your daily operations. It means continuous improvement and updating security measures in response to changing threats. "Just passing" refers to meeting the minimum requirements to obtain certification without embedding a security culture within the organization.

Common Mistakes to Avoid

1. Insufficient Documentation

What They Do Wrong: Organizations might provide insufficient documentation to support their compliance claims during audits, leading to non-compliance findings.

Why It Fails: Documentation is crucial for demonstrating compliance. Without proper documentation, auditors cannot verify that controls are in place and effective.

What to Do Instead: Maintain thorough documentation for all security controls, processes, and policies. Ensure that these documents are updated regularly and are easily accessible during audits.

2. Overlooking Regular Updates and Reviews

What They Do Wrong: Companies may become complacent after obtaining certification and neglect to update their security measures and policies.

Why It Fails: Information security is not a one-time event; it requires ongoing attention and updates to adapt to new threats and changes in the business environment.

What to Do Instead: Regularly review and update security policies and controls. Implement a process for continuous improvement in line with ISO 27001's requirement for management review.

3. Inadequate Employee Training

What They Do Wrong: Some organizations fail to provide adequate training to their employees on information security policies and procedures.

Why It Fails: Employees are often the weakest link in security. Without proper training, they may unintentionally violate security policies or become targets for social engineering attacks.

What to Do Instead: Implement a comprehensive training program that covers information security policies, procedures, and best practices. Regularly assess and update the training program based on new threats and changing business needs.
