Cyber Security Airworthiness

Overview

What is Cyber Security Airworthiness?

Cyber Security Airworthiness is the discipline of ensuring that cyber security risks do not compromise the safe operation, continued airworthiness, or mission effectiveness of an aircraft or air system throughout its lifecycle.

Corassure supports organisations in meeting CSA requirements mandated by UK MAA, EASA, and CAA, ensuring that cyber resilience is embedded throughout the aircraft lifecycle.

Frequently Asked Questions

Common questions about Cyber Security Airworthiness and how Corassure can support your programme.

Can you help us with understanding the challenges of Cyber Security Airworthiness?

Yes, we have been working in this domain since its conception in 2015, since the UK MAA initially added the Cyber Security Airworthiness requirements into Defence Standard 00-970. We are therefore likely to be one of very few external organisations that has the necessary SQEP in this challenging domain. We are happy to provide you with the necessary training or alternatively work closely with you and your organisation to act as Subject Matter Experts.

Can you help us write Cyber Security Airworthiness Artefacts?

Yes, we have a very unique capability within our company whereby we posses the necessary experience in RTCA DO-326B/ED-202B, RTCA DO-356A/ED-203A & RTCA DO-355A/ED-204A. This combined with our strong technical writing ability enables us to develop the following Cyber Security Airworthiness documentation:
