Description
Technical Field
The invention relates to the field of information data transmission, in particular to a system and a method for managing and controlling business secret security circulation based on application virtualization.
Background
The business secret refers to technical information and business information which are not known by the public, have business value and are taken by authorized persons to take corresponding security measures. The business secrets comprise two categories of core technology secrets and business information, the business secrets of the enterprises are the most important intangible assets of the enterprises, and the leakage of the business secrets can cause the loss of the core technology of the enterprises, the loss of client information, the sales of flyers, the purchase of malpractice and other business risks, so that the work of well protecting the business secrets is very critical.
The biggest difference between the business secret and the national secret is that the business secret needs to be widely circulated, and the circulation of the business secret is needed regardless of the sharing between different departments inside a company or the mutual transmission between different enterprises on an industrial chain outside the company, but the circulation is necessarily the safe circulation within a certain range and can control the authority of an accessor. Thus, secure circulation of business secrets is an important work for business secret protection.
An effective solution to the problems in the related art has not been proposed yet.
