Embodiment Construction

[0016] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0017] figure 1 It is a flow chart of a method for detecting users who scan malicious IP addresses according to a preferred embodiment of the present invention. like figure 1 As shown, in a preferred embodiment of the method for detecting and scanning users with malicious IP addresses according to the present invention, in order to detect malicious attacks, the process of learning the destination IP is firstly modified. The traditional purpose IP address learning task is only after starting the purpose unresolved learning task (step s101), after simply performing IP address learning (step s102), and then ending the current learning task (step s105).

[0018] In order to detect the attack, it is necessary to collect statistics on the IP addresses in the current specified time slice while learning the IP addresses, so as to find the IP address...

Abstract

A method for detecting out user carrying on vicious IP scanning includes counting up all source IP address of received messages , finding out source IP address being occurred most frequently in statistic value , judging whether source IP address being occurred most frequently is IP address of user carrying in vicious IP scanning or not and controlling confirmed IP address of user carrying on vicious IP scanning .

Description

field of invention [0001] The invention relates to a technology for preventing network switching equipment from being attacked by malicious IP address scanning in network communication, in particular to a method for detecting users who scan malicious IP addresses on the network switching equipment. Background technique [0002] In network communication, network switching devices are often subject to various malicious attacks. Among the many malicious network attacks, IP scanning is the most common attack method. There is no authoritative judgment on the prevention strategy for malicious IP scanning in the industry, and many equipment manufacturers believe that the prevention measures against network attacks should be divided into the functions of professional firewalls. [0003] Take a Layer 3 switch as an example. At present, among many network switching devices, the large-scale popularization and application of Layer 3 switches in China has become a new trend in the deve...
