Internet of things computer network technology can not only speed up the information transmission, but also help to break the previous time and space restrictions and improve the actual work efficiency. However, in the practical application and development of this technology, the realization of data security technology and remote control technology is the key to improve its application effect and ensure data security. Due to the obvious openness of the internet of things computer network itself, common security risks emerge one after another. Therefore, in practical application, it is necessary to pay more attention to security management and maintain network security.
