A GLOBAL FRAMEWORK TO ENHANCE CRITICAL INFRASTRUCTURE PROTECTION

(CI). They are large scale distributed systems that are highly interdependent [3], both physically and in their greater reliance on the information and communication technologies (ICT) infrastructures, which logically introduce vulnerabilities that make them increasingly complex and fragile. Failures, accidents, physical or cyber attacks can provoke major damages which can proliferate by cascading effects and then can severely affect a part or the whole society [4]. Cyber-terrorism is a fundamental threat to modern societies. The international interconnection of networks and the development of information technology has added multiple, dangerous international dimensions to computer crime. Although over the past few years, ICT have focused on simplification, universality and convergence, it now appears that they are less naively turning toward rich and diversified urbanization. Divergence is inevitable due to diverse technologies and subsidiary controls. In other words, we have a multiplicity of regionalized, autonomous, local and tailor-made solutions to store, communicate, and calculate at lower costs and closer to real use. The remainder of this paper is organized as follows. In section 2, we present new issues in ICTs. Section 3 focuses on system modelling methodologies. Section 4 proposes an implementation of the models through paradigm that enhance CI protection and tackle intra dependencies (with the policy based management and canonical architecture approach) as well as inter-dependencies (with the virtualization of CI).
