5. Maintenance: Maintaining security through updates and servicing
6. Decommissioning: Securely retiring products at the end of their useful life

Risk Assessment Framework

One of the key points is the performance of risk assessments during the design and development of new machinery. These assessments help OEMs to identify potential vulnerabilities at an early stage and take appropriate countermeasures.

The risk assessment framework includes:

• Methodologies for identifying threats and vulnerabilities
• Approaches for evaluating the likelihood and impact of potential security breaches
• Guidelines for prioritizing risks based on severity
• Strategies for implementing appropriate countermeasures

Security Requirements

The standard establishes specific security requirements for various components of agricultural machinery, including:

1. Hardware Security: Physical protection measures for electronic components
2. Software Security: Secure coding practices, authentication mechanisms, and update procedures
3. Communication Security: Protocols for secure data transmission between components and external systems
4. Data Protection: Measures to ensure the confidentiality, integrity, and availability of sensitive agricultural data

Relationship with Other Standards and Regulations

Comparison with ISO/SAE 21434

ISO 24882 shares similarities with ISO/SAE 21434, which focuses on cybersecurity engineering for road vehicles. While both standards follow similar approaches – such as emphasizing safety measures over the entire life cycle – there are significant differences. For example, ISO/WD 24882 places a particular focus on the unique challenges of agriculture, such as operating in remote rural areas and the limited connectivity of many machines.

These agricultural-specific challenges include:

• Operations in isolated or rural environments with limited connectivity
• Seasonal usage patterns that affect update schedules
• Integration with other farm systems and data platforms
• Unique environmental conditions that affect hardware durability
