In this deliverable, we summarized the activities conducted by the consortium on security management of
network slices and energy efficiency. Although only seven months left from the beginning of the activities,
many achievements have been made. First, we refined the security architecture derived from the reference
architecture devised in WP2 to achieve Zero-touch security management. In addition, two representative
use-cases of security attacks on network slices have been identified and detailed in order to illustrate how
MonB5G AI-based components are used to identify attacks and mitigate them. Finally, the deliverable
introduced the initial contribution on energy-efficiency in the context of 5G and beyond networks.
