Cyber security trend in Substation Network for automation and control Systems

摘要

A substation is a critical infrastructure. As much as a system is critical, chances of attack from outer wall or from inner wall are more. The attack could be on hardware device, software solution and on integrated database with in substation. It is most important to protect assets, software solution and implemented network for reliable and secure use within substation control room or over the remote network. Cyber security itself an intelligent process and play important role for a reliable system. Protocols based upon TCP/IP and their architectures and network of substation itself are vulnerable. A third party person can easily put a attack on substation through TCP/IP using different kind of web services and non authorized tools if vulnerability area of control system does not have enough security. Cyber security covers all the vulnerability on different level such as SCADA, IP network, EMS, LAN and WAN.
