REACT: REActive resilience for critical infrastructures using graph-Coloring Techniques
share
Nowadays society is more and more dependent on critical infrastructures. Critical network infrastructures (CNI) are communication networks whose disruption can create a severe impact. In this paper we propose REACT, a distributed framework for reactive network resilience, that is, allowing a network to reconfigure itself in the event of a security incident so that the risk of further damage is mitigated. The proposed framework takes advantage of a risk model based on multilayer networks and of a graph-coloring problem conversion to agree on a new, more resilient configuration of the network in the event of an attack. We provide two different perspectives to the resulting problem, and propose two different, network-guided approaches, which we compare in both perspectives with a number of centralized optimization techniques. Experiments show that our approaches outperform the reference approaches in terms of both risk mitigation and performance.
