The embodiment of the invention provides a semi-connection port scanning optimization method and device, and a readable storage medium. The method comprises the steps of: obtaining first scanning dataand second scanning data; respectively establishing the first null hypothesis and the first alternative hypothesis based on the first scanning data and the second null hypothesis and the second alternative hypothesis based on the second scanning data; judging whether the first null hypothesis is refused or not according to the first scanning data, so that a first judgement result is obtained, andjudging whether the second null hypothesis is refused or not according to the second scanning data, so that a second judgement result is obtained; and, adjusting port scanning parameters according tothe first judgement result and the second judgement result, so that the semi-connection port scanning mode is optimized based on the adjusted parameters. The port scanning parameters include the packet sending time and the packet sending speed. Thereby, the invention provides a simple, convenient and accurate engine adjusting and optimizing mode; the process of artificially performing a comparison test repetitively is reduced; and the engine adjusting and optimizing efficiency is increased.
Description
technical field [0001] The present invention relates to the technical field of communications, in particular to a semi-connected port scanning optimization method, device and readable storage medium. Background technique [0002] At present, because the port scanning under the semi-connection scanning technology is not based on a stable TCP connection, the scanning results are greatly affected by network fluctuations, and problems such as unstable scanning results have restricted the reliability of the data output by the Internet situational awareness system. biggest factor. How to provide a scientific scanning engine tuning method so that the port scanning engine can obtain as stable and reliable port scanning results as possible at the fastest possible scanning speed is a major problem for those skilled in the art. Contents of the invention [0003] In order to overcome the above-mentioned deficiencies in the prior art, the purpose of the present invention is to provide...
