Smart grid security challenges and approach at substation level automation

This paper identifies the emerging cybersecurity issues of the smart grid ICT component in the implementation of control and monitoring systems at the substation level. The attack surface originates from a local network across dif-ferent levels of interoperability, communication (data) model standard, and digital data collection. Given the level of complexity and overall exposure, the system is vulnerable to numerous cyber threats, resulting in significant con- sequences for system stability and availability. Since there is no absolute se-curity or ultimately safe methods of cyber threat protection, an appropriate approach must be applied, that will focus on prevention from the very design of the system, regular operation, and maintenance. In this paper, we propose a set of security measures that can be applied to elevate the security at the sub- station level.
