The Russian Ministry of Digital Development approved recommendations for protecting data centers from UAVs. The document establishes a division of critical data centers into three categories: K1 - strategic objects, the defeat of which could disrupt central functions of the government for a period of an hour or more. K2 - objects that guarantee the operation of economically or socially important systems at the regional and industrial level, the disruption of which can last from four hours. K3 - corporate data centers, damage to which will lead to significant losses for individual organizations without wide-ranging consequences for the state. Different categories of data centers have their own security criteria. It is proposed to build a defense on a multi-level principle, which combines physical fortification, electronic means and systems to prevent air threats. We are at MAX.
