ENISA evaluated the technologies from two perspectives: first, related to the actual characteristics and network resilience-enhancing features of the systems; and second, addressing the effectiveness and security problems inherent in the technologies.
The key findings were:
- The assessed technologies can improve both the resilience and security of the internet, but;
- Commercial operation experience is missing for some of the technologies;
- There are neither operational best practices nor recommendations for applied network resilience;
- There is a lack of management and co-ordination between stakeholders.
ENISA made three recommendations related to its analysis.
"Resilient connectivity of European organisations must be ensured; European expertise, best practice and operational experience must be exploited; ... and the existence of European trained experts should be ensured," it said.
The research was carried out on the back of ENISA’s Multiannual Thematic Programme, the objective of which is improving European e-communications resilience.
