A multi-objective search strategy to select optimal network hardening measures
Arkadeep Kundu, Soumya K. Ghosh · International Journal of Decision Support Systems · 2015
Limited security budget and high system availability requirements pose challenges in selecting appropriate network security hardening measures for any organisational network. This article models the network hardening measure selection problem as a multi-objective optimisation problem with three objectives – minimising hardening cost, minimising security risk and maximise overall network accessibility. A multi-objective strategy search (MOSS) algorithm has been proposed to select the best set of security hardening actions by optimising all three objectives. This process helps network administrators to select the best network security configuration, to be deployed, under resource constrained environments.
