In a data-driven society where cloud storage has emerged as a cheaper and more convenient data storing mechanism, cloud encryption has materialized as a practice that enables enterprises and consumers to take a proactive stance towards securing their data against cyberattacks, leaks, and breaches.
Encrypted Cloud Storage
Nowadays, the majority of cloud storage providers offer cloud encryption services to enhance the security of data before storing it on the cloud. In general, cloud encryption varies in technique and scope, ranging from encrypting connections, encryption of sensitive data only, to end-to-end cloud encryption that encrypts all the data transferred to the cloud. By combining encryption with other security measures, companies and businesses manage to fall in line with strict compliance regulations such as HIPAA (Health Insurance Portability and Accountability Act), GDPR (General Data Protection Regulation), and PCI DSS (Payment Card Industry Data Security Standard).
The advantages of encrypted cloud storage are undeniable, but cloud encryption is as strong as the key management mechanism. If an external party gets access to the decryption key, they can access all the data at their leisure.
This is why decryption keys should always be stored in a secure environment, separate from the encrypted data, and preferably not in the possession of the cloud provider.
Modex BCDB helps companies improve data cloud storage by connecting a blockchain backend to their existing database system. Companies can encrypt their data on-prem before uploading it to the cloud infrastructure and store their private keys in a separate blockchain network. The advantage of this approach is that it removes the need to cede control over your data to the cloud provider. Furthermore, through blockchain’s inherent properties, Modex BCDB can enhance encrypted cloud storage by enabling real-time data backup.
