Embodiment Construction

[0028] In order to make the purpose and technical solution of the present invention clearer, the network security system and method for preventing Trojan horses of the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0029] figure 2 It is a block diagram of the Trojan horse defense system of the present invention. The system includes a control terminal 240 , a server terminal 210 , the Internet 230 and a network device 220 . The control terminal 240 is the party that remotely controls the server terminal 210, and the service terminal 210 is the party that is remotely controlled by the control terminal 240; the Internet 230 is a network carrier for the control terminal 240 to remotely control the server terminal 210; the network device 220 is connected to the control terminal 240 Between the terminal 240 and the server 210, it is located on the side of the server 210, and its hardware entities are usually rou...

Abstract

The invention relates to network safety system and method, more concretely a network safety system and method for preventing Trojan. A control terminal (240) is connected with server (210) through Internet (230) so that control terminal (240) transmits instruction to server (210) and / or server (210) transmits data back to control terminal (240). The network safety system of the invention identifies Trojan virus through virus identification module (221), performs protection operation for server (210) through strategy control module (222). In one embodiment, Trojan virus is identified based on data of application layer, while in another embodiment based on data of application layer and TCP head or IP head information, and based on relation between data packet during connection. The network safety system and method for preventing Trojan of the invention are widely used among LAN and single PC.

Description

technical field [0001] The invention relates to a network security system and method, in particular to a network security system and method for defending against Trojan horses. Background technique [0002] At present, computer network technology affects all aspects of individuals and enterprises. Almost all computers and even personal communication devices such as mobile phones are connected to the Internet, and the Internet has penetrated into every corner of society. The popularity of the Internet has made information security an important social issue. Many program developers with ulterior motives have written a large number of Trojan horse (Trojan horse) programs to spy on other people's privacy and steal other people's confidential information such as online bank account numbers, etc., and then seek economic benefits. . [0003] A Trojan horse (referred to as a Trojan horse) program usually executes an operation that a user does not want while pretending to perform c...
