Development of a comprehensive cybersecurity solution for an automated process control system of a digital substation

Abstract

Currently, ensuring the cybersecurity (CSS) of the automated process control system (APCS) of a digital substation is an extremely urgent problem, since at present the introduction of control tools with complex modern digital technologies is accelerating at electric power enterprises. At the same time, digital communication at the substations is a key component of power grid modernization plans, but at the same time, this technology significantly increases the vulnerability of the automated process control systems to the cyber attacks. The paper analyzes current cyberattacks on the automated control system of a digital substation (DGS) and develops a comprehensive cybersecurity solution that meets the legislative requirements of Russia and adapted to the identified model of cyber threats. The article assesses the risk levels of cyber attacks on various information resources of the DGS.
