Abstract: The present invention provides a penetration test method and system for a network device, and relates to the field of network device vulnerability analysis and prediction. The method includes: obtaining network device vulnerability data to construct a network device vulnerability knowledge base; mining the network device vulnerability data by using a preset association rule mining algorithm, to obtain a corresponding correlation rule; and performing a penetration test on a to-be-tested network device based on the network device vulnerability knowledge base and the association rule to generate a permeability packet, to predict unknown vulnerabilities. According to association rules between the devices, the vulnerabilities, and the devices and the vulnerabilities in the vulnerability knowledge base, permeability packets are selectively generated for the devices and the vulnerabilities, thereby greatly improving the test efficiency.

Abstract: This application provides a sewing method and structure for a duvet, and the sewing method includes the following steps: first, stacking base cloth, a plurality pieces of retractable cloth and a plurality pieces of connection cloth together in sequence to form a duvet unit; then aligning two duvet units, and sewing the connection cloth on the two duvet units together in a one-to-one correspondence; and finally sewing perimeters of two pieces of the base cloth together in a one-to-one correspondence to form a closed down space. A beneficial effect of this invention is that downs in the duvet cannot run out from the gaps.
