Round 1

Reviewer 1 Report

It seems that this paper is a technical report on cybersecurity solutions based on intrusion detection system in smart grid.

This paper should thoroughly be rewritten and reorganized. Throughout this paper, it is very hard for the reviewer to get the main idea that the authors want to describe.

Moreover, this paper lacks of theoretical depth.

Reference 21 is missing.

It is not suitable for publication in Sensors.

Reviewer 3 Report

The paper proposed a cybersecurity solution based in the intrusion detection system. The proposed system is designed to detect  malicious activities targeting the Distributed Network Protocol. The DNP3 protocol is wildly used in the smart grid network and designing a cybersecurity which take in consideration the DNP3 characterisation and design is very interested research topic.

The proposed system is well explained in details. And a full details about  the tools used in the experiments were provided. One issue the authors need to consider is to justify why they picked 50% for the feature selection threshold.
