Abstract

The invention provides a method, device and system for detecting DOS attack prevention capacity. The method includes the steps that when a network attack instrument sends a large number of malicious data packets to to-be-detected gateway equipment forbidden for using a ping prevention function, an intranet host connected with the to-be-detected gateway equipment periodically sends ping commands to a public network host through the to-be-detected gateway equipment, and the intranet host judges whether the to-be-detected gateway equipment has the DOS attack prevention capacity or not according to response information sent back by the public network host, and therefore the problem that it is difficult to judge whether gateway equipment has DOS attack prevention capacity or not in the prior art is solved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method, device and system for detecting anti-DOS attack capabilities. Background technique [0002] In the prior art, the denial of service attack (Denial of Service, DOS) is mainly to continuously send a large number of malicious data packets to the network through the network attack device, so as to consume network resources such as router CPU usage time, system capacity or network bandwidth, and reduce network traffic. service performance. For example, the network attack device continuously sends a large number of malicious data packets to the gateway device to consume the bandwidth of the gateway device, making it difficult for the intranet hosts connected to the gateway device to access the Internet normally. [0003] At present, there are gateway devices capable of defending against DOS attacks in the prior art. However, it is difficult to detect whether the gateway de...
