Using DO-254 compliance checklists ensures a systematic approach to avionics hardware certification. Integrating DO-254 compliance tools like Visure Requirements ALM can further streamline traceability, verification, and certification processes, ensuring faster and more reliable FAA/EASA approval.

As avionics systems become more interconnected, DO-326A compliance is essential for ensuring cybersecurity in airborne hardware and software. While DO-254 focuses on hardware development assurance, DO-326A addresses security threats that could compromise avionics safety. Together, they form a comprehensive compliance framework for aviation certification.

Overview of DO-326A Compliance and Its Impact on Avionics Cybersecurity

✅ What is DO-326A?

• DO-326A (Airworthiness Security Process Specification) is a cybersecurity standard for avionics systems.
• It defines processes for identifying, assessing, and mitigating cybersecurity risks.
• Required for FAA, EASA, and other regulatory approvals in modern aircraft systems.

✅ How DO-326A Enhances DO-254 Compliance?

• DO-326A and DO-254 work together to ensure both safety and security in hardware components.
• While DO-254 compliance tools focus on hardware reliability, DO-326A solutions address cybersecurity vulnerabilities.
• Required for critical avionics components such as FPGAs, ASICs, and electronic control units.

How DO-326A Tools, Checklists, and Templates Support DO-254 Hardware Security

Integrating DO-326A compliance solutions into DO-254 hardware certification ensures that avionics systems are both functionally safe and cyber-secure.

✅ DO-326A Tools for Security Risk Assessment

• Identify and mitigate cyber threats in avionics hardware and software.
• Automate security testing and vulnerability analysis.
• Examples: Visure Requirements ALM, LDRA, Rapita Systems.

✅ DO-326A Checklists for Secure Hardware Development

• Ensure compliance with FAA/EASA security requirements.
• Validate secure design, testing, and verification processes.
• Cover electronic component security, access control, and data integrity.

✅ DO-326A Templates for Security Documentation

• Predefined formats for Security Risk Assessment (SRA) and Threat Model Analysis (TMA).
• Ensures traceability between security threats and mitigations.
• Aligns with DO-254 compliance templates for end-to-end certification.
