What is the main way to realize data storage security when operating and processing data information in the cloud?

The operation and processing of data information in the cloud can mainly realize data storage security through differentiated storage, decentralized storage and separated storage.

Differentiated storage

First, the data can be classified, and then the classified general data, common data and important data are stored in different locations, and the permissions are also based on the specific roles of users or the new generation. The access control model ABAC carries out classified management, and adopts the mode of combining private storage with cloud storage.

Decentralized storage

Using the existing cloud storage technology, data blocks are scattered in multiple locations. The way of decentralized preservation can not only ensure its practicability, but also improve its security to a certain extent.

"Number" and "Secret" are stored separately.

You can also use the method of separating the added data from the "key" to achieve the effect of mutual restriction between the data and the "key", and at the same time realize the same separation between the management data and the use data, and strengthen the cycle of storing, modifying and generating the "key".

If you want data security, you must strengthen security protection.

Optimize traditional network security technology: Traditional network security technology mainly includes encryption technology, access control technology, firewall technology, intrusion detection technology and authentication technology. In the era of big data, the iterative speed of information technology update is accelerated, and enterprise network information security managers need to strengthen the innovation of traditional technologies to ensure the safety of internal computer room environment, video surveillance system, firewall, intrusion prevention system, database audit system and application delivery system.

Using big data security technology: ensure the security of network information and data in the whole life cycle, and reduce the risk of enterprises being attacked by diseases and viruses. Data source authentication technology, ciphertext appended message authentication code technology, time stamp and so on are applied to the information data collection process, and privacy protection technology, data encryption technology, key management technology and remote backup technology are applied to the data storage process to reduce the risk of data being attacked and stolen.
