A method for improving network vulnerability detection rate based on automatic network quality perception

Abstract

The present invention proposes a method for improving the network vulnerability detection rate based on network quality automatic perception, including: the detection end sends data packets to the destination end at the packet sending rate Vt, and detects the packet return response time of the destination end in real time, and draws the response time of the data packet curve; the control rate Vt of the detection end increases gradually. When the resources occupied by the transmitted data packets exceed the current remaining bandwidth, and when the fluctuation of the response time curve enters the allowable time range of the first response, the rate growth is stopped and the packet sending rate Vt is gradually reduced, so that When the response time falls within the allowable time range of the second response, it is calculated as the actual available network bandwidth K; according to the detected network bandwidth K, the packet transmission rate V during the actual detection is calculated, and while sending the data packet, Record the response time T of each data packet, and adjust the packet sending rate V. The invention can achieve rational utilization of network resources and avoid the problems of resource waste and network congestion.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a method for improving the detection rate of network loopholes based on automatic perception of network quality. Background technique [0002] With the wide application of the Internet, there are more and more websites built by enterprises or private individuals in the network space. With the rapid increase in the number of websites, security problems are gradually exposed, and various loopholes appear one after another, followed by a rapid increase in network attacks. The security of the website is also more and more valued by the webmasters, so various vulnerability detection techniques and tools have been derived. [0003] Traditional vulnerability detection technology has little consideration for the actual network environment. Scanning the target website without knowing the actual network environment may have the following problems: [0004] 1. Affect the normal busin...

AI Technical Summary

Problems solved by technology

[0004] 1. Affect the normal business of the website: When the network is busy or the scanning intensity consumes more resources than the actual network environment, scanning may increase the network burden, affect the normal website business, and even lead to network paralysis;

[0005] 2. Cause packet loss and affect data accuracy: When the network is busy or consumes too much resources, then high-intensity scanning will not only affect the network environment, but also may cause abnormalities in the detection data return due to network congestion, causing Packet loss affects the accuracy of scanned data;

[0006] 3. Waste of resources: The resource consumption of scanning may be lower than the actual network environment. If the original scanning rate is maintained, there will be a large amount of bandwidth remaining, and too much time will be wasted at the same time.
