ISO 24882: Cybersecurity for Agricultural Machinery and Tractors

ISO 24882 “Agricultural machinery, tractors, and earth-moving machinery – Product cybersecurity” is currently at draft stage (ISO/DIS 24882). As the European draft prEN ISO 24882:2025, it already plays a concrete role in the European standardization system. You can obtain the draft from your national standardization body (see where to buy standards). It is the first sector-specific cybersecurity standard for manufacturers of agricultural machinery, tractors, and earth-moving machinery. According to Annex ZA of the draft, the European version is intended for the Machinery Regulation, not for the Cyber Resilience Act (Regulation (EU) 2024/2847), or CRA.

Between the CRA and sector-specific product requirements

The CRA sets horizontal cybersecurity requirements for all products with digital elements. ISO 24882 covers related topics for mobile machinery, but it was not drafted for the CRA. According to Annex ZA of the draft, the European version is being prepared under the standardization request for the Machinery Regulation (C(2025)129, M/605). It is not a separate legal basis. Once adopted and cited in the Official Journal of the EU, it can give a presumption of conformity with the Annex III requirements of the Machinery Regulation that it covers: protection against corruption (section 1.1.9) and safety and reliability of control systems (section 1.2.1(a)).

For connected machinery, two regulatory levels meet here: the general cybersecurity obligations of the CRA and the function-specific safety requirements of the Machinery Regulation, which ISO 24882 is intended to support. The Machinery Regulation mainly addresses physical risks. As machines become more connected and automated, however, it also becomes relevant where safety meets cybersecurity. ISO 24882 creates a structured link between traditional machinery safety requirements and the new cybersecurity obligations.

Relationship to existing standards

ISO 24882 should not be read in isolation. It builds on established cybersecurity concepts and integrates approaches from several families of standards. Its closeness to ISO/SAE 21434, the standard for cybersecurity engineering of road vehicles, is central. ISO/SAE 21434 addresses the automotive industry. ISO 24882 transfers comparable principles to mobile machinery, with adapted assessment criteria and with the specific operating conditions of agriculture and construction in mind.

The standard also 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 adds the cybersecurity dimension: functional safety protects against random failures, while cybersecurity addresses deliberate attacks on system integrity.

The draft does not refer to the IEC 62443 series for industrial automation. Manufacturers with experience in IEC 62443-4-2 (requirements for components) or IEC 62443-4-1 (product development processes) will recognize conceptually related approaches in ISO 24882. They appear in a different sector, however, and without the formal division into security levels.

Structure and logic of the standard

At its core, ISO 24882 takes two steps: risk assessment (clause 5) and technical requirements for risk mitigation (clause 6). Further clauses cover the product lifecycle (clause 7), vulnerability handling (clause 8), components from suppliers and third parties (clause 9), and documentation (clause 10).

Clause 5 describes a risk-based process that starts with defining the system under consideration. This step sets the system boundaries and identifies relevant interfaces, for example to external communication networks, cloud services, or integrated third-party components. Next, damage scenarios are identified, together with the assets through which an attacker could bring them about, such as data flows, configuration data, personal data, or hardware and software components. The damage scenarios cover at least the safety, financial, privacy, and availability impact on the user.

Building on this, threat scenarios are identified, explicitly including accidental corruption. The standard names threat modeling approaches such as STRIDE, PASTA, or VAST as possible methods, but it does not prescribe a specific technique. Risks are rated by combining an impact assessment with the likelihood of occurrence: impact is rated on four levels, likelihood from five factors based on ISO/IEC 18045, and the result is a risk value from 1 to 5. From this follows which risks need treatment and which can be accepted.

Clause 6 translates the identified risks into concrete technical requirements. These include:

• secure software updates (authenticity and integrity checks, notification of security updates)
• integrity and authenticity checks of software, for example through secure boot
• hardening: secure default configuration and a secured production mode without open development interfaces
• logging and monitoring of security-relevant events
• authentication and role-based access control for users and for diagnostic access
• confidentiality and integrity of stored and transmitted data, data minimization
• resilience against disruptions, denial-of-service protection, and protection of external networks
• secure by design, defense in depth, and cryptography following best practices

Each requirement follows the same structure: applicability, requirement, rationale, guidance, and verification criteria. This structure helps developers and test bodies alike to classify the requirements in a traceable way.

How ISO 24882 differs from IEC 62443 and ISO/SAE 21434

A common misunderstanding is that ISO 24882 is derived directly from IEC 62443. IEC 62443, however, primarily addresses stationary industrial automation systems with long operating cycles and clearly defined zone boundaries. Mobile machinery operates in changing environments, has variable network connections, and is often operated by people without IT expertise. These differences require adapted concepts, for example when assessing attack scenarios or designing update mechanisms.

Nor is ISO 24882 simply ISO/SAE 21434 transferred to agricultural machinery. The automotive standard focuses strongly on integration into connected mobility ecosystems (V2X communication, backend services). For mobile machinery, the ability to withstand unpredictable operating conditions comes first.

Common misunderstandings

In the context of the CRA, note that according to the draft, ISO 24882 gives no presumption of conformity with the CRA, only with the Machinery Regulation requirements it covers. It does contain process requirements for vulnerability handling (clause 8) and the cybersecurity support period (section 7.4). The CRA's reporting obligations and its other essential requirements must be demonstrated separately, for example with the EN 40000 series. Manufacturers must therefore check which further organizational and process measures they need for full CRA compliance.

Another common misunderstanding is to treat the standard as a complete cybersecurity checklist. In fact, it defines a framework that must be applied according to the product and its context. Setting concrete security objectives and selecting suitable measures is the manufacturer's task, based on its own risk assessment.

ISO 24882 also sets no requirements for corporate IT security. Securing the company networks into which machines are integrated falls under other standards, such as ISO/IEC 27001, or under sector-specific guidelines. The standard focuses on the product itself and its behavior in the intended operating context.

Outlook and relevance for manufacturers

ISO 24882 is currently at draft stage. In Germany, the draft E DIN EN ISO 24882:2026-01 was open for comment until January 28, 2026. Once the comment period has closed and the standard has been finally approved, publication as an international standard is expected. If the European version (EN ISO 24882) is cited in the Official Journal of the EU, it becomes a harmonized standard. Manufacturers who can show that they develop according to it could then claim a presumption of conformity with the essential requirements it covers. According to Annex ZA of the draft, this would apply under the Machinery Regulation, for sections 1.1.9 and 1.2.1(a) of its Annex III.

Other sector-specific and horizontal cybersecurity standards are emerging at the same time, for example ETSI's vertical standards (ETSI EN 304 6xx series) or the EN 40000 series for the CRA. Manufacturers of agricultural machinery should therefore follow not only ISO 24882 but also the development of cross-sector standards, so that they can use synergies in implementation.

The standard is not an end in itself. It is a tool for systematizing cybersecurity requirements in a sector where digitalization is advancing fast. Autonomous driving systems, precision farming applications, and the connection of machines to fleet management systems increase the attack surface. ISO 24882 offers a structured approach to these risks, but only if manufacturers treat it as a living process that needs continuous adjustment.

What the standard does and does not do

ISO 24882 closes a gap in the standards for mobile machinery. It makes cybersecurity requirements specific to the sector and relates them to the requirements of the Machinery Regulation. It is neither a stand-alone security checklist nor a direct derivative of existing standards. It is a set of rules in its own right that focuses on the particular challenges of mobile, connected machines.

For manufacturers, it provides an important frame of reference, but only when they apply it in the context of their specific product and the regulatory requirements that apply to it. The standard provides structure, not completeness. Working out the product-specific details remains the manufacturer's task.
