Nowadays, the eclectic industry focuses more attention on security production and stability; therefore, they did not spend enough attention on data security, system security and internet safety. This paper analyses the importance and emergency of information safety in the development of power industry. Meanwhile, different kinds of threats, protection and detection models against the threats in power industry is discussed. This paper applies the core of information security professional knowledge, such as operating systems, computer network, cryptography, network security and other relevant theoretical knowledge, as while as combining them with power system architecture. This paper proposes a terminal-based security information security protection system in order to help electric power industry system. At the meantime, the system also strengthens the construction of the whole power system of information security system.
