The invention discloses a network system, an attack message intercepting method, an attack message intercepting apparatus, and a device, and belongs to the technical field of communication. The method comprises the following steps of: receiving a first intercepting request transmitted by a network server; according to an information database, inquiring a control device identifier corresponding to a first device information; according to the control device identifier, transmitting a second intercepting request to the control device, and thereby enabling the control device to transmit a third intercepting request to a gateway device, wherein the third intercepting request at least carries the first device information, and the gateway device is enabled to intercept a second attack message, transmitted by a source device, according to the third intercepting request. According to the invention, at a remote end of the network server, active interception of attack messages is realized, the network server is avoided from receiving the attack messages again, and the network server is free from processing the attack messages, thus, time for processing the attack messages is saved, information leakage or influence on operation of the network server caused by the attack messages is avoided, and safety performance is improved.
Description
technical field [0001] The invention relates to the field of communication technology, in particular to a network system, an attack message interception method, device and equipment. Background technique [0002] With the development of Internet technology, the interaction between various devices in the network system is becoming more and more convenient, and the network server, as a device that provides services, will be open to and interact with multiple user devices. Provides an opportunity for attackers. [0003] Usually, an attacker sends an attack packet to the network server, so that the network server responds to the attack packet, thereby affecting the normal operation of the network server. The attack packets can include two types of large-flow packets and malformed packets. If an attacker sends a large-flow packet to the network server, the entrance of the network server is easily blocked by large-flow packets. If it is full, the network server will not be able ...
