Embodiment Construction

[0031] The system and method of the present invention will be further described in detail below in conjunction with the accompanying drawings and the embodiments of the present invention.

[0032] The local area network protection system provided by the present invention can prevent data from being improperly accessed and ensure the security of data transmission between users of the network neighborhood; it is used in the network packets of the network neighborhood, adding appropriate marks ( For example, parameters or symbol labels), so that when the network uses SMB (Server Message Block), SMB2 or CIFS (Common Internet File System) to transmit files or data, it must have a mark to pass through.

[0033] figure 1 It is a schematic diagram of a local area network protection system according to an embodiment of the present invention. In this embodiment, the LAN protection system 10 can be used as a server (server) and a client (client) or a LAN system between clients, which in...

Abstract

The present invention provides a local area network protection system and method, including sending a request command in a sending end, adding a mark or a white list to a network packet, and receiving the request command in a receiving end, and checking the network packet Whether there is the mark or white list in the network packet; if there is the mark or white list in the network packet, the network packet will be allowed to pass; if there is no mark or white list in the network packet, the network will be disconnected. By adopting the present invention, improper data access can be avoided, and the security of data transmission between users of network neighbors can be ensured.

Description

technical field [0001] The invention relates to a network security method, in particular to a local area network protection system and method. Background technique [0002] With the development of the Internet, network packets can be transmitted between a client (Client) and a server (Server) through a local area network (LAN). When one of the LAN connections is disconnected, through channel routing technology, network packets can still be transmitted through other channels, thereby maintaining the continuity of network transmission; in addition, using multiple channels to transmit network packets can also be Improve the network transmission rate. [0003] Today, with the rapid development of information technology, enterprises and individuals rely more and more on information equipment, and information security has naturally become the most important issue while developing and using computer software and hardware. Lack of information security will lead to various serious ...
