A method and system for realizing virtual local area network data security

Abstract

The invention discloses a method and system for achieving virtual local area network data safety. The method comprises the steps of previously setting a registry of an operation system to automatically start platform overall-situation software when the operation system of a terminal is started and operated, shielding a data output port, used for outputting data to an external network, of the platform overall-situation software when the platform overall-situation software is operated, and further opening a website access port, used for visiting the external network, of the platform overall-situation software and a data input port, where data are input from the external network, of the platform overall-situation software. Thus, workers can handle official business on the platform overall-situation software, can copy text information outside a platform into the platform, cannot copy information in the platform outwards and can surf external networks during working. Furthermore, enterprises information leakage is avoided. The system simulates the characteristics of a local area network separated from the external network to form a virtual local area network and guarantees that data can enter the platform and are prevented from being brought away from the platform.

Description

technical field [0001] The invention relates to the technical field of data security of an operating system, in particular to a method and system for realizing virtual local area network data security. Background technique [0002] In the traditional corporate office mode, since corporate employees work directly on the company's computers, there is a risk that corporate employees will intentionally or unintentionally transmit information on their office computers to the external network, resulting in the risk of corporate information leakage. [0003] In order to solve the problem of the above-mentioned leakage risk, in the prior art, a method often adopted is to configure all the computers in the enterprise in a local area network, and set the local area network to be unable to access the external network. But in this way, it is very inconvenient for people who need to look up information on the Internet for office work. [0004] The essence of the above problems is such a...

Problems solved by technology

[0002] In the traditional corporate office mode, since corporate employees work directly on the company's computers, there is a risk that corporate employees will intentionally or unintentionally transmit the information on their office computers to the external network, resulting in the risk of corporate information leakage

[0003] In order to solve the problem of the above-mentioned leakage risk, in the prior art, a method often adopted is to configure all the computers in the enterprise in a local area network, and set the local area network to be unable to access the external network

But in this way, it is very inconvenient for people who need to look up information on the Internet

[0004] The essence of the above problems is such a contradiction: it is necessary to be able to access the external network while working, but it is not possible to transfer local information and files to the external network.
