Method for improving detection rate of network bug based on automatic perception of network quality

Abstract

The invention provides a method for improving the detection rate of a network bug based on automatic perception of the network quality. The method includes steps: a detection terminal transmits a datapacket to a target terminal with a packet-transmitting rate Vt, detects a packet-returning response time of the target terminal in real time, and draws a response time curve of the data packet; the detection terminal controls the rate Vt to be gradually increased, and when an occupied resource of the transmitted data packet exceeds a current residual bandwidth and the response time curve fluctuation enters a first response allowing time range, the increase of the rate is stopped, the packet-transmitting rate Vt is gradually reduced, the response time is reduced within a second response allowing time range, and a network bandwidth K for practical application is calculated; and according to the detected network bandwidth K, the packet transmission rate V during practical detection is calculated, the data packets are transmitted, the response time T of each data packet is recorded, and the packet transmission rate V is adjusted. According to the method, network resources can be reasonably utilized, and problems of resource waste and network congestion are avoided.

Description

technical field [0001] The invention relates to the field of Internet technologies, in particular to a method for improving the detection rate of network vulnerabilities based on automatic perception of network quality. Background technique [0002] With the wide application of the Internet, more and more websites are built by enterprises or private individuals in the cyberspace. The surge in the number of websites, the gradual exposure of security problems, the emergence of various loopholes, followed by the rapid increase in network attacks. The security of the website has also been paid more and more attention by the website administrators, so a variety of vulnerability detection technologies and tools have been derived. [0003] The traditional vulnerability detection technology takes less consideration of the actual network environment. Scanning the target website without knowing the actual network environment may have the following problems: [0004] 1. Affect the no...

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.
