Introduction

Computer, communications and networking technologies are currently widely used in power systems. There are various kinds of information in communications and computer networks Possible security attacks pose a threat to the security of data and communications in power systems. These potential possible attacks target the power system Security vulnerabilities in communication protocols at various levels of the system and imperfections in the security management of power system information infrastructure.

To this end, we adopted the international standard to develop GB /Z 25320 "Power System Management and its information exchange data and communication security", pass Over the relevant communication protocols and in the information infrastructure management to add specific security measures to enhance and enhance the power system data and Communication security.
