Aerospace Cybersecurity for Airworthiness, Certification, an
Aerospace cybersecurity is not just about protecting connected systems. It is about protecting systems whose failure, compromise, or unintended behavior can affect safety, certification, and continued airworthiness. In this space, cybersecurity work is shaped by standards and frameworks such as RTCA DO-326A for the airworthiness security process, DO-356A for methods and considerations, DO-355A for continuing airworthiness, and Europe’s EASA Part-IS requirements for managing information security risks that can impact aviation safety.
Vultara helps aerospace organizations bring structure to that work with traceable cybersecurity workflows, clearer lifecycle visibility, and on-premises deployment for environments where sensitive engineering and security data need tighter control.

Why Aerospace Is Different
Aerospace programs operate in a world of certification evidence, tightly controlled changes, long service lives, and high consequences for incomplete traceability. Cybersecurity decisions may need to support aircraft design assurance, certification activities, operational risk management, and continued airworthiness over time. RTCA describes DO-326A as the airworthiness security process specification, while DO-355A specifically addresses information security guidance for continuing airworthiness.
That makes aerospace cybersecurity a different problem than generic product security. Teams need a way to connect threats, requirements, mitigations, evidence, and post-delivery responsibilities without losing control of the engineering baseline.
Standards and Regulations Shaping Aerospace Cybersecurity
For aerospace and aviation cybersecurity, the standards most often associated with airworthiness security include DO-326A, DO-356A, and DO-355A. RTCA describes DO-326A as handling information security threats to aircraft safety, DO-356A as providing methods and guidelines used within that airworthiness security process, and DO-355A as guidance for operation, maintenance, and continuing airworthiness activities.
On the regulatory side, EASA Part-IS establishes requirements for managing information security risks with a potential impact on aviation safety. EASA states that Part-IS provisions became applicable on October 16, 2025 for organizations in the scope of the delegated act and on February 22, 2026 for the remaining organizations and competent authorities covered by the implementing act.
