As part of the study run by ENISA, a set of metrics-specific questions was
sent to a group of stakeholders. These questions concerned how resilience is measured on a sector basis (the
surveyed participants were from public and private organisations, as well as national regulators, academia, etc.).
This document presents the results of that study and aims to provide a non-technical overview to policy experts
in the area of resilience. The key challenges to resilience measurements and the most interesting aspects of the
answers received are summarised and analysed in this document. This report also summarises a number of
recommendations arising from the analysis of the information received.
The rest of the report is organised as follows. Section 2 presents the main challenges impeding the adoption of a
commonly accepted framework for resilience metrics and measurements. In section 3, we summarise the main
recommendations for future actions in the area of network and service resilience metrics and measurements. Finally
section 4, includes all the detailed input we received from the questionnaires and interviews with stakeholders.
