Cybersecurity engineering is a critical discipline to ensure safe and secure human experiences using cyber-physical systems. The main challenge is to preserve trust for connected cyber systems in an evolving digital economy increasingly threatened by unpredictable events.

For the standard ISO 21434, based on a system architecture, the Systems Cybersecurity Designer enables:

• Selection of Assets for protection
• Threat and Cyberattack Modeling
• Risk Evaluation
• Cybersecurity requirements creation to mitigate identified risks

For the standard DO-326A focusing on an avionics system architecture, the Systems Cybersecurity Designer enables:

• Definition of the Security Scope
• Threat definition and Attack Path Modeling
• Security Risk Assessment
• Specification of Security Requirements to mitigate identified risks, and evaluation of their effectiveness

The Systems Cybersecurity Designer supports the following risk assessment methodologies:

• Threat Analysis and Risk Assessment as per ISO/SAE 21434:2021
• Cybersecurity Risk Assessment as per RTCA DO-326A/ED-202A
