Research on data desensitization and penetration of intranet and extranet based on access control

As an important environment for data circulation within large enterprises, enterprise LAN carries a large amount of data of users in the industry. The importance of data security and privacy is increasing under the trend of digital development and has become an important work research direction for enterprises. While, the reliable methods for data protection during the process of penetrating and sharing LAN data to the Internet is rare. This paper proposes an enterprise LAN data desensitization penetration scheme. This scheme provides corresponding desensitization methods through the fine-grained control method of user permissions and the different degree of data confidentiality, so as to realize data application initiation, identity determination, permission control, data desensitization, and data sharing. The whole process data is Safe and controllable traceability. This solution provides new ideas and methods for enterprise intranet and extranet penetration.
