Encryption of cloud storage is very important.

Without encryption, all employees of cloud computing providers might be able to see the data. If a cloud storage provider is compromised, encryption is also critical to maintaining data protection.

These three important cloud storage encryption best practices will help ensure data security.

Encrypt static and dynamic data

“Cloud storage encryption” usually refers to encrypting the data (static data) stored in the disk in the cloud data center. Admittedly, this kind of encryption is important, but you need to do more.

Please encrypt both static and dynamic data. Dynamic data refers to data transmitted to or from the cloud, or from one location in the cloud to another. Using IPSec or similar encryption protocols can help prevent anyone from accessing data while it is being transmitted.

Depending on the type of data, application level encryption should be used. For example, many databases provide data encryption independent of storage level encryption.

Treat all data equally

For cloud storage encryption, treat all data equally. Some IT professionals suggest that the administrator classify the data according to the importance of the data, and then protect and encrypt the data according to the classification. The problem with this method is that if the administrator misclassifies the data, unprotected data may be leaked.

From the perspective of management, all data should be regarded as sensitive data and protected accordingly, which is easier and safer.

Encryption with zero knowledge

Zero knowledge encryption enables enterprises to store their encryption keys outside the cloud. Although cloud storage providers can host enterprise data, they cannot read it because they do not have encryption keys.

Zero knowledge encryption prevents key transmission to cloud storage providers. This approach of cloud storage encryption can eliminate any possibility for cloud computing providers to access data.
