Artefact Builder Lite walks you through the first DO-326A artefact, the Aircraft Security Scope Definition (ASSD). Answer the questions, watch your connection map build as you go, and export your ASSD when you're done.
Connection map
As you add your assets and how they connect, the builder draws the map. Connections that cross your security perimeter show in red, so you can see straight away where the risk comes in.
