Introduction

Industrial equipment is rapidly becoming more connected, intelligent, and remotely accessible. Modern machinery can include embedded software, firmware, web interfaces, APIs, cloud connectivity, wireless communication, remote-management capabilities, and integration with operational technology (OT) environments.

While these capabilities improve automation and operational efficiency, they also expand the potential attack surface. A vulnerability in an industrial product could allow attackers to compromise sensitive information, manipulate functionality, disrupt operations, or use the equipment as an entry point into connected systems.

The European Union Cyber Resilience Act (CRA) introduces cybersecurity requirements for products with digital elements throughout their lifecycle. Regulation (EU) requires manufacturers to consider cybersecurity risks during planning, design, development, production, delivery, and maintenance. It also requires manufacturers to document cybersecurity risk assessments and address vulnerabilities through appropriate vulnerability-handling processes.

For industrial equipment manufacturers, CRA-aligned cybersecurity assessment services can help identify weaknesses, validate security controls, and generate technical evidence that contributes to a broader cybersecurity and compliance-readiness programme.

Understanding the EU Cyber Resilience Act for Industrial Equipment

The CRA establishes horizontal cybersecurity requirements for products with digital elements placed on the EU market. These products can include hardware, software, and associated remote data-processing solutions.

Manufacturers are expected to perform and document cybersecurity risk assessments based on factors such as intended purpose, reasonably foreseeable use, operational environment, assets that need protection, and expected product lifetime. The assessment must be updated as appropriate during the product’s support period.

The CRA also places emphasis on vulnerability handling, including identifying and documenting vulnerabilities, addressing vulnerabilities, and considering the security of integrated third-party components.

Security testing is therefore an important technical activity for manufacturers seeking to understand whether industrial products are exposed to exploitable weaknesses.

CRA reporting obligations are already applicable to manufacturers for actively exploited vulnerabilities and severe incidents affecting the security of products with digital elements. Manufacturers must provide an early warning within 24 hours of becoming aware and a full notification within 72 hours.

Why Industrial Equipment Requires Dedicated Cybersecurity Assessment

Industrial products differ from conventional IT applications because security weaknesses can potentially affect physical processes, production environments, safety, and operational continuity.

A comprehensive cybersecurity assessment can examine multiple layers of an industrial product.

1. Embedded Software and Firmware Security

Firmware and embedded software frequently control critical product functions. Weaknesses such as insecure update mechanisms, hardcoded credentials, outdated libraries, insecure services, or improper access controls can create significant security exposure.

Security assessment can help identify these weaknesses before attackers exploit them.

2. Network and Communication Security

Industrial equipment may communicate using Ethernet, Wi-Fi, Bluetooth, proprietary protocols, industrial protocols, APIs, or cloud services.

Assessment can identify:

• Unnecessary open ports and services
• Weak network authentication
• Insecure communication protocols
• Poor segmentation
• Unencrypted data transmission
• Exposed management interfaces
• Weak remote-access controls

3. Web and API Security

Modern industrial equipment may provide browser-based dashboards or APIs for configuration, monitoring, analytics, and remote management.

Testing can identify vulnerabilities involving authentication, authorization, session management, input validation, API access controls, and insecure configurations.

4. Third-Party Components

Industrial products often rely on operating-system packages, open-source libraries, commercial software, and other third-party components.

The CRA requires manufacturers to exercise due diligence when integrating third-party components and to address vulnerabilities identified in components integrated into their products.

Security assessments can therefore complement dependency analysis, vulnerability management, SBOM activities, and secure development practices.

Our Methodology for CRA-Aligned Cybersecurity Assessment of Industrial Equipment

Cyberintelsys follows a structured and risk-based approach to assess the security of industrial equipment and products with digital elements. The assessment is tailored to the product architecture, attack surface, operational environment, and cybersecurity risks identified by the manufacturer.

1. Scope and Asset Identification

The assessment begins with an understanding of the industrial product and its ecosystem.

The scope may include:

• Hardware and embedded components
• Firmware
• Operating systems
• Network interfaces
• Web applications
• APIs
• Mobile applications
• Cloud services
• Remote-access functionality
• Wireless interfaces
• Supporting infrastructure

This helps establish the product’s overall attack surface.

2. Cybersecurity Risk Assessment

Testing activities are aligned with the product’s intended purpose, foreseeable use, operational environment, connected assets, and potential security impact.

This allows testing priorities to be established according to realistic threats rather than relying only on generic vulnerability scanning.

3. Vulnerability Assessment

Automated tools and manual techniques are used to identify vulnerabilities across the defined scope.

The assessment can identify issues such as:

• Known software vulnerabilities
• Weak configurations
• Insecure services
• Authentication weaknesses
• Access-control flaws
• Outdated components
• Encryption weaknesses
• Vulnerable APIs
• Insecure interfaces

Findings are reviewed and validated to reduce false positives.

4. Penetration Testing

Penetration testing takes the assessment further by safely attempting to exploit identified vulnerabilities.

Depending on the product architecture, testing may include:

• Authentication testing
• Authorization testing
• Privilege escalation
• Input validation testing
• API penetration testing
• Web application testing
• Network penetration testing
• Firmware security testing
• Remote-access testing
• Configuration security testing

This provides manufacturers with practical insight into how vulnerabilities could potentially be exploited.

5. Source Code and Component Security Review

Where source code is available, code-level assessment can help identify security weaknesses that may not be visible through black-box testing.

The assessment can also consider third-party dependencies and software components to help manufacturers strengthen their vulnerability-management process.

6. Remediation and Retesting

Identified vulnerabilities are documented with technical evidence, risk ratings, affected components, and remediation recommendations.

After fixes are implemented, retesting can verify whether the vulnerabilities have been effectively addressed.
