An efficient process to reduce infrastructure vulnerabilities facing malevolence

Abstract In daily life, we are all used to frequent ‘systems’: public transports, industrial parks, shopping areas, stadiums or many others. And with the exponential increase of technologies, we are now living in a kind of ‘open World’ within which goods, persons or information are moving increasingly faster. The consequence is an amazing new way of life and also a number of new threats for our society. To insure the security of all citizens, and also of infrastructures, national skills or anything else, we need to secure our systems efficiently. To do so, we need appropriate tools to accurately analyze vulnerabilities in order to counter all kinds of malevolence. After giving an overview of different methods linked to that problem, we will explain our process to analyze the vulnerabilities of a complex infrastructure and what points are fundamental to take into account facing human aggressions.
