However, the discarded data sometimes contains valid data discarded due to configuration reasons, or unrecognized new virus attack means, which requires saving the discarded data information, and conducting security analysis on the data confidence to identify
[0005] Therefore, in the existing technology, the industrial security gateway directly discards the data that does not pass the whitelist filter, because the discarded data is not analyzed for security, it may lead to the loss of some valid data, and it is impossible to discover new ones in time. attack methods, resulting in serious security risks and reducing the reliability of industrial networks

The embodiment of the invention provides a data message detection method and device based on an industrial network; the method is applied to exchange equipment including at least one filter panel and at least one storage panel; in the method, the exchange equipment receives a data message sent by the network side, and queries a self-stored port mapping list according to the port of the received data message; the data message is redirected to the filter panel corresponding to the receive port according to the query result, and mirrored to the storage panel corresponding to the receive port for storage; the filter panel determines whether to transfer the data message or not according to the filter result. The method and device can mirror the data message to the filter panel for storage, so the filtered data message can be safely parsed so as to effectively prevent data loss, timely finding new attach means, and improving industrial network reliability.
Description
technical field [0001] The invention relates to the technical field of industrial data security, in particular to an industrial network-based data packet detection method and device. Background technique [0002] With the continuous application and improvement of industrial network technology, the Internet has become more and more closely integrated with all aspects of society, and a series of network applications such as informatization construction of various units of industrial enterprises have flourished. While enjoying the richness and convenience of the Internet, people also increasingly feel that all kinds of security threats are growing rapidly. Frequent network attacks, virus floods, unauthorized access, information leaks and other issues have greatly troubled users, jeopardizing information networks and core businesses. cause serious damage. [0003] Industrial control network integration architecture, including programmable control products, numerical control pro...
