This talk comes from a university project. The main objective was to incorporate a specific framework for the electric sector (CAFFEINE) into the CAT taxonomy (Cyber-Attack-Taxonomy). Throughout the talk, attendees will be able to understand the basic concepts related to the electric sector (devices, communications, etc.). In addition, different cyberincidents that have affected the electric sector and their impact will be discussed. In order to show the power of CAFFEINE, different practical exercises will be performed with different DEMOS and several Open Source tools will be used to obtain #TTPs.
