Problems solved by technology

[0004] However, with the development of business globalization and the continuous expansion of enterprise intranet and public network IP, if the above-mentioned existing technical solutions are adopted, the distribution of scanning source servers will inevitably become more scattered. Uneven source load will become increasingly prominent, and scanning server operating costs will gradually increase

Embodiment Construction

[0042] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0043] One of the core ideas of the present invention is that it does not strongly depend on the known conditions in the CMDB system where the target server has been divided into the city, breaks the thinking pattern of the scan source server dividing the scanning IP range according to the administrative division, and puts all the target IPs to be scanned into the public Pool, through the scan source ICMP (Internet control message protocol, Internet Control Message Protocol) test to obtain the approximate location information of a...

Abstract

The invention provides a port scanning method and system based on self-learning path selection. The method includes: obtaining the geographic locations of all scanning sources; selecting N different scanning sources therefrom to perform the first scan on all hosts to be scanned, and obtaining the round-trip delay time of messages between each host to be scanned and the scanning source, N Greater than or equal to 3; for each host to be scanned, calculate its geographic location according to the geographic location of the scan source and the round-trip delay time; match each host to be scanned with the geographic location of all scan sources, and select the one closest to the host to be scanned The scanning source is used as the matching scanning source corresponding to the host to be scanned, so as to obtain the mapping relationship between all the hosts to be scanned and all matching scanning sources; and use the matching scanning source to perform a second scan on the port of the host to be scanned. Accordingly, the optimal match between the scanning source and the host to be scanned is realized, the scanning efficiency is improved, and the overall intrusion discovery and loss stop efficiency are ensured.

Description

technical field [0001] The invention relates to computer network technology, in particular to a port scanning method and system based on self-learning path selection. Background technique [0002] As information technology increasingly penetrates into all aspects of production and operation, for many large enterprises and organizations, their IT infrastructure is often spread across the country and even in different geographical locations around the world. These IT infrastructures are interconnected through the network to serve the operation of the enterprise. , It is also related to the information security and even normal operation of the enterprise. In order to reduce the risk of server software being invaded and dragged due to insufficient security protection, it is necessary to periodically poll and scan the port information of all internal and public IP (Internet Protocol, Internet protocol) addresses. In order to meet the needs of different regions and operators for ...
