With the rapid development of Internet of Things applications, the power Internet of Things technologies and applications covering the various production links of the power grid "transmission, transmission, transformation, distribution and use" are becoming more and more popular, and the terminal, network and application security risks brought by them are receiving more and more attention. Combined with the architecture and risk of power Internet of Things, this paper first proposes the overall security protection technology system and strategy for power Internet of Things; then analyzes terminal identity authentication and authority control, edge area autonomy and data transmission protection, and application layer cloud fog security management. And the whole process real-time security monitoring; Finally, through the analysis of security risks and protection, the technical difficulties and directions for the security protection of the Internet of Things are proposed.

The normal operation of key measurement and control equipment in power grid (KMCEPG) is of great significance for safe and stable operation of power grid. Firstly, this paper gives a systematic overview of KMCEPG. Secondly, the cyber security risks of KMCEPG on the main station / sub-station side, channel side and terminal side are analyzed and the related vulnerabilities are discovered. Thirdly, according to the risk analysis results, the attack process construction technology of KMCEPG is proposed, which provides the test process and attack ideas for the subsequent KMCEPG-related attack penetration. Fourthly, the simulation penetration test environment is built, and a series of attack tests are carried out on the terminal key control equipment by using the attack flow construction technology proposed in this paper. The correctness of the risk analysis and the effectiveness of the attack process construction technology are verified. Finally, the attack test results are analyzed, and the attack test cases of terminal critical control devices are constructed, which provide the basis for the subsequent attack test. The attack flow construction technology and attack test cases proposed in this paper improve the network security defense capability of key equipment of power grid, ensure the safe and stable operation of power grid, and have strong engineering application value.
