Introduction

Industrial equipment is becoming increasingly connected through embedded software, firmware, network interfaces, APIs, cloud platforms, remote-access technologies, and operational technology environments. This connectivity supports automation, remote monitoring, predictive maintenance, and improved operational efficiency. However, it also introduces new cybersecurity risks.

A vulnerability within connected industrial equipment can potentially expose sensitive information, disrupt operations, compromise connected systems, or provide attackers with an entry point into wider IT and OT environments.

The EU Cyber Resilience Act (CRA) establishes cybersecurity requirements for products with digital elements placed on the European Union market. Under Regulation (EU), manufacturers must perform a cybersecurity risk assessment and take its results into account during planning, design, development, production, delivery, and maintenance. The assessment must also be documented as part of the relevant technical documentation.

For industrial equipment manufacturers, a structured cybersecurity assessment can help identify security weaknesses, evaluate product risks, validate controls, and generate technical evidence that supports a broader CRA compliance-readiness programme.

Understanding CRA Compliance Readiness for Industrial Equipment

The CRA applies to products with digital elements, including hardware, software, and associated remote data-processing solutions that meet the Regulation’s scope. Manufacturers are responsible for ensuring that applicable products meet the essential cybersecurity requirements.

The CRA places emphasis on security by design and by default, vulnerability handling, cybersecurity risk assessment, security updates, documentation, and lifecycle security.

For industrial equipment, these requirements can become particularly relevant when a product contains:

• Embedded software or firmware
• Network interfaces
• Industrial communication protocols
• Web-based management interfaces
• APIs
• Remote-access capabilities
• Wireless connectivity
• Cloud services
• Third-party software components
• Connected sensors or devices

Manufacturers must also exercise due diligence when integrating third-party components so that these components do not compromise the cybersecurity of the product.

A cybersecurity assessment can help organizations understand whether these technical components introduce vulnerabilities or attack paths that require remediation.

Why Cybersecurity Assessment Is Important for Industrial Equipment

Industrial products can have a wider security impact than conventional standalone software because they may interact directly with operational processes and physical environments.

A cybersecurity assessment helps manufacturers move from simply identifying technical weaknesses to understanding how those weaknesses could affect the product and its surrounding environment.

1. Identifying Security Vulnerabilities

Assessment activities can identify weaknesses across different layers of an industrial product, including:

• Firmware
• Embedded software
• Operating systems
• Network services
• Web interfaces
• APIs
• Authentication mechanisms
• Third-party components

Identifying these weaknesses early provides development and security teams with an opportunity to remediate them before they become exploitable security risks.

2. Evaluating the Product Attack Surface

Connected industrial equipment may expose multiple interfaces to administrators, users, maintenance personnel, networks, and external services.

A cybersecurity assessment can evaluate:

• Network interfaces
• Remote-access services
• Administrative interfaces
• Web dashboards
• APIs

Understanding these entry points helps manufacturers prioritize security controls according to realistic attack scenarios.

3. Validating Security Controls

Assessment activities can also determine whether implemented security controls work as intended.

Testing may evaluate:

• Authentication
• Authorization
• Encryption
• Access controls
• Network segmentation
• Remote-access security
• Update mechanisms

4. Understanding Exploitation Risk

Vulnerability identification alone may not show the practical impact of a security weakness.

Controlled penetration testing can help determine whether an identified vulnerability could potentially allow an attacker to gain unauthorized access, escalate privileges, access sensitive information, manipulate product functionality, or compromise connected systems.

This provides manufacturers with more actionable information for remediation and risk prioritization.

Our Methodology for Cybersecurity Assessment to Support CRA Compliance Readiness

Cyberintelsys follows a structured, risk-based methodology for assessing industrial equipment and products with digital elements. The approach can be tailored according to the product architecture, attack surface, operational environment, and identified cybersecurity risks.

1. Scope and Asset Identification

The assessment begins by understanding the product and identifying its relevant digital and physical components.

Depending on the product, the scope may include:

• Hardware
• Firmware
• Embedded software
• Network interfaces
• Web applications
• APIs
• Mobile applications
• Cloud services

This provides a foundation for understanding the overall attack surface.

2. Cybersecurity Risk Assessment

The CRA requires manufacturers to perform a cybersecurity risk assessment and use its results when implementing applicable cybersecurity requirements.

The assessment can consider:

• Intended purpose
• Foreseeable use
• Operating environment
• Connected assets
• Data requiring protection
• Expected product lifetime

The resulting risk picture helps determine where security testing and remediation should receive priority.

3. Vulnerability Assessment

Automated tools and manual techniques can be used to identify potential vulnerabilities.

Testing may identify:

• Known vulnerabilities
• Outdated software
• Weak configurations
• Exposed interfaces
• Vulnerable dependencies
• API security issues

Findings can then be validated and prioritized according to technical severity and potential impact.

4. Penetration Testing

Penetration testing provides a deeper assessment by safely attempting to exploit identified vulnerabilities.

Depending on the product architecture, testing may include:

• Network penetration testing
• Web application penetration testing
• API penetration testing
• Authentication testing
• Remote-access testing
• IoT security testing
• OT security testing

The testing scope should be carefully designed for industrial environments so that security validation does not unnecessarily disrupt operations.

5. Source Code and Component Review

Where source code is available, Source Code Review can complement external security testing.

It can help identify weaknesses such as:

• Hardcoded credentials
• Insecure functions
• Input-validation weaknesses
• Vulnerable dependencies

This is particularly relevant because the CRA requires manufacturers to exercise due diligence regarding third-party components integrated into their products.

6. Remediation and Retesting

Security findings should be prioritized according to severity, exploitability, and potential product impact.

After remediation, retesting can verify whether identified vulnerabilities have been effectively resolved.

This creates a continuous process:

Identify → Assess → Remediate → Retest → Improve

7. Security Reporting and Documentation

A cybersecurity assessment report can provide technical evidence that supports broader product-security activities.

The report may include:

• Executive summary
• Scope
• Assessment methodology
• Identified vulnerabilities
• Severity ratings
• Technical evidence
• Retesting results

Under the CRA, cybersecurity risk assessment and the means chosen to meet applicable requirements must form part of the technical documentation.
