ISO/DIS 24882 specifies cybersecurity requirements for agricultural machinery and tractors and links them to the Cyber Resilience Act. It explains the relationship to the Machinery Regulation, ISO/SAE 21434 and IEC 62443.
Between the CRA and sector-specific product requirements
The Cyber Resilience Act (CRA) establishes horizontal cybersecurity requirements for all products with digital elements. ISO 24882 takes up these requirements and translates them into the specific context of mobile work machines. It should not be understood as an independent legal basis, but as a harmonized standard that—if finally adopted and published in the EU Official Journal—can create a presumption of conformity with the CRA’s essential requirements.
This positioning is important because it links two regulatory levels: the general cybersecurity obligations from the CRA and the function-specific safety requirements of the Machinery Regulation. The latter primarily addresses physical risks but becomes relevant at the cybersecurity interface due to the increasing networking and automation of machines. ISO 24882 creates a structured connection between traditional machine safety requirements and the new obligations for cybersecurity.
The role of ISO 24882 between the CRA, the Machinery Regulation and existing safety standards is not always clear to many manufacturers. If you want to clarify what regulatory function the standard actually serves for your products, a short classification discussion can be helpful.
Relationship to existing norms and standards
The standard should not be viewed in isolation. It builds on established cybersecurity concepts and integrates approaches from several standards families. Central is its proximity to ISO/SAE 21434, the standard for cybersecurity engineering in road vehicles. While ISO/SAE 21434 addresses the automotive industry, ISO 24882 transfers comparable principles to mobile work machines—albeit with adapted evaluation criteria and taking into account the specific operating conditions in agriculture and construction.
In addition, the standard references the ISO 25119 series on safety-related parts of control systems in agricultural machinery and the ISO 19014 series for earth-moving machinery. These functional safety standards define requirements for the reliability of control systems under fault conditions. ISO 24882 complements this perspective with the dimension of cybersecurity: while functional safety protects against random faults, cybersecurity addresses deliberate attacks on system integrity.
The IEC 62443 series for industrial automation is also taken into account, particularly with regard to network segmentation and access controls. Manufacturers already familiar with IEC 62443-4-2 (component requirements) or IEC 62443-4-1 (product development processes) will recognize conceptually related approaches in ISO 24882—although in a different sectoral context and without the formal separation into Security Levels.
Structure and content logic of the standard
ISO 24882 follows a two-stage approach: risk assessment and derivation of technical requirements.
Chapter 5 describes a risk-based process that begins with defining the system under consideration. This step sets system boundaries and identifies relevant interfaces—such as to external communications networks, cloud services or integrated third-party components. Next comes the systematic identification of assets that need protection: these include not only software elements but also the physical safety of people and the protection of operational data.
Based on these assets, damage scenarios are developed and threats are identified. The standard uses threat modeling approaches such as STRIDE, PASTA or VAST as possible methods but does not mandate a specific technique. Risk classification is carried out through a combination of impact assessment and likelihood. From this, it is determined which risks require treatment and which may be accepted.
Chapter 6 translates the identified risks into concrete technical requirements. These include, among others:
- Secure software update (including signature verification and notification mechanisms)
- Access control and authentication
- Network security and segmentation
- Data protection and encryption
- Logging and monitoring of security-relevant events
- Physical tamper resistance of components
Each of these requirements is structured according to a consistent scheme: applicability, requirement, background, guidance and verification criteria. This layout allows both developers and testing bodies to classify requirements in a comprehensible way.
Distinction from IEC 62443 and ISO/SAE 21434
A common misunderstanding is to assume that ISO 24882 is an immediate derivative of IEC 62443. In fact, IEC 62443 primarily addresses stationary industrial automation systems with long operating cycles and clearly defined zone boundaries. Mobile work machines, by contrast, operate in changing environments, are subject to variable network connections and are often operated by people without IT expertise. These differences require adapted concepts—for example in evaluating attack scenarios or designing update mechanisms.
Likewise, ISO 24882 should not be seen as a mere transfer of ISO/SAE 21434 to agricultural machinery. While the automotive standard focuses heavily on integration into connected mobility ecosystems (V2X communication, backend services), robustness against unpredictable operating conditions is paramount for work machines. Retrofit scenarios and upgrading older machine fleets also play a larger role, which is reflected in the structure of the standard.
Common misunderstandings and distinctions
In the CRA context, it should be noted that although the standard can create a presumption of conformity, it does not guarantee immediate compliance. The CRA imposes additional requirements on vulnerability management, transparency obligations and reporting that go beyond the technical specifications of ISO 24882. Manufacturers must therefore check which further organizational and procedural measures are necessary to achieve full CRA compliance.
A widespread misunderstanding is to treat the standard as a definitive checklist for cybersecurity. In reality, it defines a framework to be applied product- and context-specifically. Setting concrete security objectives and selecting appropriate measures is the responsibility of the manufacturer based on the conducted risk assessment.
It should also be noted that ISO 24882 does not set requirements for operational IT security. Securing company networks into which machines are integrated falls within the scope of other standards—such as ISO/IEC 27001 or sector-specific guidelines. The standard focuses on the product itself and its behavior in the intended operational context.
In practice, manufacturers often ask which CRA requirements are covered by ISO 24882 and which additional organizational or procedural measures remain necessary. We are happy to discuss without obligation how this distinction looks for your product portfolio.
Outlook and relevance for manufacturers
ISO 24882 is currently in draft form. After the commenting procedure and final adoption, publication as an international standard can be expected. If the European version (EN ISO 24882) is referenced in the EU Official Journal, it will attain the status of a harmonized standard. As a result, manufacturers who can demonstrate development in accordance with this standard may be able to claim a presumption of conformity with the essential requirements of the Machinery Regulation.
At the same time, other sector-specific and horizontal standards in the cybersecurity field are emerging—such as the vertical ETSI standards (ETSI EN 304 6xx series) or the EN 40000 standards series for the CRA. Manufacturers of agricultural machinery should therefore keep an eye not only on ISO 24882 but also on the development of overarching standards to exploit synergies in implementation.
The standard is not an end in itself but an instrument to systematize cybersecurity requirements in a sector where digitalization is advancing rapidly. Autonomous driving systems, precision agriculture applications and the networking of machines with fleet management systems increase the attack surface. ISO 24882 offers a structured approach to address these risks—but only if it is understood as a living process that requires continuous adaptation.
Conclusion
ISO 24882 fills a gap in the standardization landscape for mobile work machines by specifying cybersecurity requirements in a sector-specific way and linking them to the CRA and the Machinery Regulation. It is neither an isolated security checklist nor a direct derivative of existing standards, but an independent rule set that focuses on the special challenges of mobile, connected machines. For manufacturers it provides an important orientation framework—however, only when applied in the context of the specific product and applicable regulatory requirements. The standard provides structure, not completeness. Product-specific deepening remains the manufacturer’s responsibility.
ISO 24882 provides an important orientation framework for cybersecurity in mobile work machines, but it does not replace a product-specific assessment in the context of the CRA. If you would like to clarify what the standard specifically means for your products, development processes and evidence, this can be examined in a non-binding discussion.
