Construction of security protection system based on online security monitoring technology of acquisition terminal

With the completion of the construction goal of "full coverage, full collection and full cost control" of the power consumption information acquisition system, the power consumption field of power grid has been fully transferred into the operation and maintenance period. In the process of security detection and sampling of the acquisition terminal, it is found that there are security risks in the field operation of the acquisition terminal, lack of online security protection processing mechanism for network risks and their own vulnerabilities, and there is a risk of being vulnerable to large-scale malicious attacks. Therefore, it is urgent to study the online security monitoring technology of the acquisition terminal and strengthen the construction of online security protection system of the acquisition terminal Design. In this paper, through the construction of the security protection system based on the online security monitoring technology of the acquisition terminal, the online security monitoring system of the acquisition terminal is built to collect and analyze the security data information of the acquisition terminal in real time, and monitor the acquisition terminal uniformly, so as to realize the security situation awareness of the acquisition terminal and the region; through the security analysis, the security risks in the operation environment of the acquisition terminal are found in time, so as to realize the security Threat identification and attack traceability, improve the level of terminal security operation protection. Through the construction of the security protection system based on the online security monitoring technology of the acquisition terminal, it can effectively support the security monitoring of all kinds of terminal equipment in the power Internet of things.
