Embodiment Construction

[0018] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below through specific examples.

[0019] figure 1 A schematic diagram of the information leakage prevention system. As shown in the figure, the defense system mainly consists of two parts: client and server. The client is installed on every computer that needs to operate the protected files to perform protection operations. The server is installed on a separate computer in the network, and is used to monitor and control the client computer, manage certificates and keys, and authenticate the user's operations on the protected files on the client. The feature is that the client and the server are connected through a network. figure 1 The combination devices of each functional feature constitute the system of the present invention.

[0020] The server has the following devices: monitoring device 1 , identity authent...

Abstract

The invention relates to an information leakage prevention system and an implementation method thereof in a collaborative work environment in the technical field of network security. It includes two parts: client and server. The client is installed on each computer that needs to operate the protected files to perform protection operations; the server is installed on a separate computer in the network to monitor and control the client. Computers, manage certificates and keys, and protect files on the client side for users, and the client and server are connected through the network. The methods include: verifying the identity and authority of the user; performing decryption operations; monitoring the opened files at all times; encrypting the saved content, so that the content saved on the disk is always encrypted information, which ensures that the file is encrypted by any user. Copying to other places is encrypted. It fundamentally solves the problem of information leakage in the collaborative work environment, and considers various application environments, with high usability.

Description

technical field [0001] The invention relates to the technical field of network security, in particular to an information leakage prevention system in a collaborative work environment and an implementation method thereof. Background technique [0002] The rapid development of network technology has enabled more and more companies and institutions to improve work efficiency through internal networks or VPN networks. However, while the network improves work efficiency, it also brings many hidden dangers to information security. [0003] However, most of the current information security research focuses on solutions to security threats from the Internet, or on the prevention of internal network attacks and the restriction of unauthorized access to information by internal network members. How to prevent information leakage in a large-scale network working environment, for example, how a manufacturing company prevents competitors from easily using electronic graphics files obtain...
