Problems solved by technology

[0004] There are online hosts and offline hosts in the intranet segment. If the entire intranet segment is scanned, the scanner will send data packets to a large number of offline hosts, resulting in low scanning efficiency.
And once a network device is scanned, it will easily lead to an increase in the CPU usage of the network device or even the risk of the entire network being paralyzed

Embodiment Construction

[0059] In order to make the above objects, features and advantages of the present application more obvious and comprehensible, the present application will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0060] With the development of the Internet of Things technology, enterprises deploy more and more hosts in the internal LAN. The host is a terminal device that sends and receives information, such as: PC computer, network camera, IP phone and other network terminals based on TCP / IP protocol communication.

[0061] Enterprise network security personnel usually use scanners to scan each IP address in the intranet segment to find problems with the host.

[0062] When the internal network segment is too large and the number of online hosts is small, it takes too long to scan the entire network segment, resulting in low scanning efficiency. For this, before scanning the intranet, the embodiment of the prese...

Abstract

The embodiment of the invention provides a host scanning method and device. The method comprises the steps of acquiring address information of an online host in a preset network segment; determining a target host from the online hosts by adopting the address information of the online hosts; and scanning the target host. In the embodiment of the invention, the target host required to be scanned is determined by determining the online host in the intranet and adopting the address information of the online host, for example, the target host is scanned by taking other hosts except the high-risk host as the target hosts. By determining the high-risk host in the online hosts, the high-risk host is not scanned, so that the risk of network paralysis can be avoided. Compared with scanning of all the hosts in the intranet, invalid scanning can be reduced, the scanning time is greatly shortened, and the scanning efficiency is improved.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a scanning method and a scanning device. Background technique [0002] A scanner is a program that automatically detects security weaknesses of local or remote hosts. It can quickly and accurately discover the vulnerabilities of the scanning target and provide the scanning results to the user. [0003] With the development of the Internet of Things technology, more and more enterprises have deployed hosts on the intranet, such as cameras, TV boxes, and smart card machines. Usually, enterprise network security personnel will scan the entire network segment of the intranet to discover the types, quantities and risks of devices on the intranet, and facilitate the next step of vulnerability or weak password detection. [0004] There are online hosts and offline hosts in the intranet segment. If the entire intranet segment is scanned, the scanner will send data...
