Abstract: With the development of industrial Internet, the types of Web containers used by enterprises continue to increase, which makes Web container asset management more complicated and increases many network security risks and hidden dangers. In order to further improve network security defense capabilities, this article proposes a method of Web container detection and identification based on active detection. In the detection part, the Web container probe construction method is used to construct the Web container probe; in the identification part, a Web container identification method based on payload content is used to achieve Web container identification based on protocol decoding. By combining these two methods, four types of Web containers were identified, and a total of ten versions could be recognized.
