Safety isolation method for cloud side multi-tenant data storage

Abstract

The invention provides a safety isolation method for cloud side multi-tenant data storage. According to the safety isolation method for cloud side multi-tenant data storage, isolated distributed storage is applied to multi-tenant data storage, when a tenant applies for a data storage space, storage software API provided by an operator is called, a specific virtual storage area is provided for the tenant through division according to the ID of the tenant, the storage area of each tenant is relatively independent and isolated, and when a tenant uses private data, the distributive storage software collects tenant data from a private space in a disk array on the physical layer according to the ID of the user and provides a data service for the tenant in a concentrated mode; for each tenant, the data isolated distributed storage process is automatically completed by a system, transparent encryption and decryption is conducted on the volume levels, of cloud side multi-tenant data, in the storage disk array on the physical layer, safety isolation of the multi-tenant data in the cloud computing environment is achieved, and the problem that a cloud service provider administrator views, tampers and deletes sensitive data of the tenants without authorization is solved.

Description

technical field [0001] The present invention relates to the technical field of computer applications, in particular to a cloud multi-tenant data storage security isolation method. Background technique [0002] With the rapid development of cloud computing and changes in business models, "data" is the cornerstone of survival, with a wide variety, complex applications, and frequent leaks. Data security issues have become increasingly prominent. Data security in the cloud has become the most important issue for users. The concerns mainly focus on two aspects: one is worrying about cloud operators or cloud operation and maintenance personnel illegally viewing, using or leaking cloud data; the other is worrying about other tenants’ unauthorized access to their own data, or worrying about data migration under the tenant’s usage mode Or after the service is cancelled, the deletion of tenant data is not complete, causing key data leakage risks. At present, there are many types of d...

[0002] With the rapid development of cloud computing and changes in business models, "data" is the cornerstone of survival, with a wide variety, complex applications, and frequent leaks. Data security issues have become increasingly prominent. Data security in the cloud has become the most important issue for users. The concerns mainly focus on two aspects: one is worrying about cloud operators or cloud operation and maintenance personnel illegally viewing, using or leaking cloud data; the other is worrying about other tenants’ unauthorized access to their own data, or worrying about data migration under the tenant’s usage mode Or after the service is cancelled, the deletion of tenant data is not complete, causing key data leakage risks

At present, there are many types of data security products in the domestic and foreign markets, mainly to solve traditional data security problems, and the multi-tenant data security problems brought about by cloud computing need to be dealt with urgently
