Understanding malicious attacks against infrastructures : overview on the assessment and management of threats and attacks to industrial control systems

This report describes approaches to the assessment and management of malicious threats and attacks relating to critical infrastructures in general, and electric power infrastructures in particular. Securing infrastructures implies taking into account both the natural and man-made (intentional) events. While protecting against the natural disruptive events is a feasible (yet not trivial) task, benefiting by well-established practices, dealing with intentional attacks comes up across many difficulties, especially due to the unpredictability of such events. The report outlines the state-of-the-art in dealing with threats and malicious attacks, considering both physical and cyber actions. Several approaches taken at national and international levels towards securing the critical infrastructures are also provided.
