ABSTRACT
In the recent years, the majority of the world’s Critical Infrastructures (CIs) have evolved to be more flexible, cost efficient and able to offer better services and conditions for business growth. Through this evolution, CIs and companies offering CI services had to adopt many of the recent advances of the Information and Communication Technologies (ICT) field. CIs are defined as systems and assets either physical or virtual, extremely vital to a state. The incapacitation or destruction of such infrastructures would have a debilitating impact on security, economy, national safety or public health, loss of life or adversely affect the national morale or any combination of these matters. CIs consist of several different, heterogeneous subsystems and need holistic solutions and services to provide coverage against a broad range of cybersecurity attacks.
