ABSTRACT
The novel electricity industry, known as smart grids, integrates the power generation and information transmission system with telecommunication networks to form a two-way infrastructure of electricity and information, which is a prerequisite for an intelligence network. The smart grid structure will be very efficient and cost-effective in terms of expense and management due to the presence of new telecommunication systems and technologies. However, although having many benefits, the integration of these two structures has disadvantages in terms of system security and protection.
Concerning the information security of telecommunication systems of the smart grid, it must be said that the electrical network, which has a minor connection to the Internet, is exposed to considerable threats. These risks include security attacks by enemy gatherings and hackers to disrupt generating, transmission, and distribution of electricity or to manipulate and corrupt data sent over the smart grid. The various layers of cyber security must be designed to minimize the chance of attacks. So, all connections to an Internet network need to be extremely secure. It is not necessary to detect an attacker’s intrusion on the network connection port of the Internet. However, through the network, particularly, in the wireless data transmission environment, this system must be able to detect intrusion. All components of systems and networks in a smart grid must be assessed when designing security. At the same time, in the event of an accident, the system must be able to respond appropriately as soon as a disturbance occurs. So, in such networks, the speed of detection, report, decision-making, and response is a vital characteristic of security.
