Cyber security applied to P&C IEDs

This paper highlights basic cyber security features that Protection and Control Intelligent Electronic Devices (P&C IEDs) should implement considering the current cyber security standardization efforts. Although it can be said that all functional aspects regarding the securization of IEDs are covered by these standards, there are still some gaps or lack of definition. Currently, it´s difficult to install IEDs from different manufacturers within the same cyber security system. This paper emphasizes those aspects requiring additional definition and implementation of interoperability.
