D5.1 Resilience actions supporting systems

The D5.1 focuses on the creation of a resilience actions supporting systems. The main objective is to define resilience actions supporting systems for IDUNN component, which can detect the needed actions for resilience, decision support and alternative mitigations.
The document focuses on describing the progress that has been made in WP5, but especially in task T5.1. Specifically, a design of the system for analysing and handling cybersecurity alerts, capable of responding to these with the intention of mitigating the damage that these can do in the monitored environment, has been carried out. Since the system needs to connect with the cybersecurity components in charge of detection developed in WP2, WP3 and WP4, it has been designed how the connection with these components will be made. On the other hand, modules that are able to notify alerts and implement resilience actions in the network have been developed, thus mitigating the detected cybersecurity risk. In addition, the connection with the DLT has been designed to verify the integrity and immutability of the alerts that reach the ODIN component. Finally, the first analysis and design of the open source and software vulnerability governance tool has also been described.
