Five requirements for navigating Europe's cybersecurity compliance rules

[Cengiz Özemli]

What you will learn:​

• Manufacturers aiming to enter the EU market need to understand and implement the five core requirements of the CRA.
• Best practices in production include adding security gates to the release pipeline, training engineers in secure coding, and utilizing hardware root-of-trust features.
• By taking these steps, manufacturers meet regulatory requirements and deliver stronger products that build trust in competitive markets.

The European Union Cyber Resilience Act, which came into force last year, has led to a significant shift in how manufacturers in the EU manage cybersecurity for connected products.
As digital components are incorporated into everything from industrial machinery to smart sensors, the CRA establishes a consistent framework to ensure these products remain secure throughout their entire lifecycle.
While certain products already regulated under existing EU laws and open-source software used for non-commercial purposes are excluded, the CRA covers everything from industrial control systems to smart devices.

Manufacturers wishing to enter the EU market must understand and implement the five core requirements of the CRA. This will help them achieve compliance and build customer trust.

Security by default and by design​

Under the CRA, products and software must have strong security controls from the outset. This "security by design" principle requires manufacturers to:

• Utilize a threat modeling process during product development to identify potential attack vectors early.
• Implement authentication controls, encrypted communications, and secure defaults rather than relying on end-user configuration.
• Maintain secure software development practices, such as code reviews and automated testing for common vulnerabilities.

Best practices in production include adding security gates to the release pipeline, training engineers in secure coding, and utilizing hardware root-of-trust features.

By taking these steps, manufacturers meet regulatory requirements and deliver stronger products that build trust in competitive markets.

Manufacturers can meet the CRA's requirements by embedding cryptographic modules and access controls at the hardware and firmware levels, reducing the need for costly post-release patches.

Incident management and reporting​

The CRA mandates that covered organizations establish robust processes for detecting, managing, and reporting security incidents. Key elements include:

• A clear incident response plan defining roles, communication channels, and escalation paths.
• Continuous monitoring of device behavior in the field, including logging, alerting, and anomaly detection.
• A streamlined reporting procedure that notifies EU authorities within strict timelines if a product's vulnerability poses a significant risk.

Manufacturers should invest in security operations center capabilities specific to IoT and embedded systems, ensuring rapid triage of vulnerability reports from customers or third parties.

Automated dashboards and predefined templates can help achieve reporting deadlines faster, reducing regulatory risk.

Vulnerability management​

Effective vulnerability management is key to the CRA's goal of mitigating risk. Manufacturers must:

• Maintain an up-to-date record of all software elements, including components, libraries, and firmware versions used in products.
• Periodically conduct vulnerability scans and penetration tests to identify vulnerabilities before release.
• Provide timely security updates and patches to customers, along with clear instructions and pathways for installing them.

In production, this means establishing a coordinated vulnerability disclosure program, building relationships with security researchers, and utilizing over-the-air update systems for industrial devices.

By automating patch deployment and verifying installation success, organizations can demonstrate to regulators that critical fixes are reaching end-users quickly.

Third-party risk management​

Connected products often depend on third-party components, external developments, or cloud services. The CRA requires manufacturers to address every step in the supply chain:

• Vet suppliers and software vendors for their security posture and ensure they follow standards like ISO 27001 or IEC 62443.
• Incorporate security requirements into contracts. This should cover responsibilities regarding patches, incident notifications, and liabilities.
• Regularly audit the security performance of third parties and verify compliance with agreed-upon controls.

Large-scale manufacturers can implement a risk rating system for suppliers, scoring them based on criteria such as past breach history, encryption practices, and responsiveness to vulnerabilities.

This data-driven approach helps procurement teams identify high-risk suppliers and take action on supply chain weaknesses.

Manufacturers should invest in security operations center capabilities specific to IoT and embedded systems.

Product risk assessment​

The CRA mandates that each product undergoes a detailed risk assessment before and after being placed on the market. This assessment includes:

• Identifying potential threats, attacker pathways, and their impact on confidentiality, integrity, and availability.
• Classifying products based on their risk profiles, such as critical industrial controllers requiring stricter controls than consumer electronics.
• Periodically reviewing risk assessments in light of new threat intelligence, software updates, or changes in deployment contexts.

Manufacturers should adopt standardized methodologies like Failure Mode and Effects Analysis (FMEA) or Common Criteria evaluation to quantify residual risk.

By combining technical analysis with business impact studies, teams can prioritize mitigation efforts on components that would lead to the most severe consequences if compromised.

Implementing CRA compliance in production​

Achieving CRA compliance requires teamwork across engineering, legal, and commercial functions:

1. Governance and policy: Establish a CRA task force with members from different functions to define policies, assign responsibilities, and monitor progress toward compliance milestones.
2. Continuous improvement: Use metrics such as mean time to patch, incident resolution time, and supplier risk scores to measure effectiveness and drive ongoing improvements.
3. Align processes: Integrate security checkpoints into existing workflows in product development, procurement, and customer service operations.
4. Leverage tools and automation: Utilize vulnerability scanners, DevSecOps workflows, and automated reporting systems to streamline routine tasks and improve efficiency.
5. Training and culture: Provide regular security awareness training to engineers, QA, and supply chain managers on CRA requirements and incident response protocols.

By taking these steps, manufacturers meet regulatory requirements and deliver stronger products that build trust in competitive markets.

The EU's Cyber Resilience Act introduces a new level of responsibility for the security of connected products. For manufacturers eyeing EU markets, adhering to the five core requirements—security by default and design, incident management and reporting, vulnerability management, third-party risk management, and product risk assessment—is indispensable.
Following these best practices ensures CRA compliance and improves the organization's overall cybersecurity posture, leading to safer and more reliable products in the long run.
