Problems solved by technology

Even if the firewall of the gateway server connected to other terminals can detect the attack message and intercept it to prevent other terminals from being attacked, if the first terminal keeps transmitting attack messages, it will occupy the network bandwidth, thereby affecting the transmission of normal messages

Embodiment Construction

[0050] The embodiment of the present invention provides a method for blocking attack messages, which can be used in message transmission systems, such as figure 1 As shown, the system may include at least a management server, multiple gateway servers, and multiple terminals. The management server can be connected with all gateway servers in the system, and can be used to manage each gateway server. The gateway server can not only be connected with the management server, but also be connected with multiple terminals to provide services for the connected terminals, such as transmitting terminal messages. Moreover, all the gateway servers can be connected to each other, and can be used to forward the message of the terminal to other gateway servers. The terminal can be connected with the gateway server, access the network through the gateway server, and send messages to other terminals through the gateway server.

[0051] The method can be implemented jointly by the first gatew...

Abstract

The invention relates to a method, device and system for preventing an attack message, and belongs to the technical field of communication. The method comprises: receiving a first message sent by a first terminal, wherein a source terminal identifier carried by the first message is the identifier of the first terminal, and a destination terminal identifier carried by the first message is the identifier of a second terminal; Obtaining an identifier of a second gateway server corresponding to the second terminal, taking the identifier of the second gateway server as a target gateway server identifier, taking the identifier of the first gateway server as a source gateway server identifier, and adding the source gateway server identifier and the target gateway server identifier into the firstmessage; Sending the first message subjected to the addition processing to a second gateway server; Detecting a source terminal identifier carried in a subsequently received message after receiving atransmission refusal notification which is sent by the management server and carries the identifier of the first terminal; And when the source terminal identifier of the received second message is theidentifier of the first terminal, refusing to forward the second message. By adopting the method and the device, the influence of the attack message on the transmission of the normal message can be avoided.

Description

technical field [0001] The present disclosure relates to the technical field of communication, in particular to a method, device and system for blocking attack messages. Background technique [0002] With the development of communication technology, a terminal can establish a connection with a gateway server, and transmit messages with other terminals in the network through the gateway server. A firewall may be installed on the gateway server to ensure the security of communication between terminals. [0003] When an attacker sends an attack message to other terminals in the network through the first terminal, the first terminal sends the attack message to the connected first gateway server, and the firewall in the first gateway server can detect the attack message and intercept it, The attack message cannot be transmitted to other terminals to ensure the security of other terminals. [0004] In the process of realizing the present disclosure, the inventors found at least ...
