Security Technology by using Firewall for Smart Grid

Abstract

Due to the increasing development of computer systems and information networks, power grids should change extensively too. Nowadays, substantial movement has begun to implement the Smart Grid industry around the world. Since with the creation of smart electricity grids, it is possible to access the internal network from the external spaces, it is also necessary to protect information and data against unauthorized access. Therefore, a firewall should be used for information security. The firewall based on existing security regulations, decides which data is incoming to the network or going out of the network. Considering the discussions of passive defense topics at the national level and also the high importance of information security in Smart Grids, in this paper, in addition to examining the Firewalls, its advantages and disadvantages are also stated. Although the firewall has a major role in establishing security, and its installation and appropriate configuration can only be one of the primary activities in this field, we should also take advantage of other security mechanisms to enhance the security of the Smart Grid.

Towards cyber security for low-carbon transportation: Overview, challenges and future directions

“…For example, the smart grid management center can access substations, but the substation can not access the core network of the control center. The firewall of smart grid in [101] was divided into three layers. The first layer of firewall is based on analyzing the IP packet and its header fields.…”

An Overview of the Firewall Systems in the Smart Grid Paradigm

“…In [14], the authors introduce a firewall system for the energy sector focusing on the Distributed Network Protocol 3 (DNP3). Their implementation is based on the iptables firewall and specifically on the u32 byte-matching module which is used to identify common cyberattacks in the payload of the DNP3 packets.…”

Economic dispatch problem in smart grid system with considerations for pumped storage

“…The firewall operates in accordance with current security regulations. Given the current debates on passive defense and the significance of data security in smart grid systems, it is necessary to deploy additional security measures in addition to the firewall to increase the security of the smart grid system [6]. The remainder of this work is arranged in the following manner.…”
