Research of electric power information security protection on cloud security

Informatization is an important feature of smart grid. With the construction of smart grid and the constant depth development of electric power information, the information networks of electric power have been continued to invade by all kinds of network threats. Traditional information security protection system for electric power had been unable to meet the security threats demand of ever changing and growing. Moreover, the cost of electrical safe operation was increased. Meanwhile, with the further application of electric power information engineering, operation capacity of electric power is required to be fully improved so that safe and stable operation is essential to electric power information system. Cloud security is service form that cloud computing provides for users. In view of the advantages of cloud computing and cloud security, architecture of electric power information security protection based on cloud security (AEPISP-CS) is put forward which combines with the current power information security status. Meanwhile, anti-virus system, spam mail filtering, threat detection based on cloud security are described in detail.

I. Introduction

Power system information security has been a threat to power system security, stability, economy and high quality to run. Meanwhile, strong and smart grid implementation process of China was affected. Power information security has become an important part of electrical enterprise production, operation and management. However, the power information security had the following defects: Information security awareness was low, unified information security management practices was deficient, information security architecture and construction was imperfect, and information security monitoring and risk assessment mechanism was unsound. Therefore, how to make electric power information network systems from hackers and viruses invade, and how to protect data transmission security, reliability had become an important guarantee of safe and stable operation for strong and smart grid. Research of power system information security, development of corresponding applications, and draft of information systems security strategy of information system recovery prevention when subjected to external attack were the current the important items of information.
