Always Encrypted with VBS Enclaves in Azure SQL DB: Data Exposed
Introduction
The purpose of this blog post is to provide a step-by-step guide to understanding and implementing Always Encrypted with VBS Enclaves in Azure SQL Database. The post will discuss the key concepts, benefits, and architecture of Always Encrypted with VBS Enclaves, and how it can help protect data stored in Azure SQL Database.What is Always Encrypted with VBS Enclaves?
Always Encrypted with VBS Enclaves is a feature of Azure SQL Database that allows data stored in the database to be encrypted. The encryption is performed using VBS Enclaves which are isolated execution environments, designed to protect sensitive data from being accessed by the database server. By using VBS Enclaves, the data is encrypted in such a way that the database server cannot access it, even if the server is compromised.Benefits of Always Encrypted with VBS Enclaves
The primary benefit of Always Encrypted with VBS Enclaves is that it provides an additional layer of security for data stored in Azure SQL Database. The encryption is performed on the data before it is stored in the database, which means that even a compromised database server cannot access the data. Additionally, the encryption is performed within the VBS Enclave, which means that the data is encrypted even if the database server is compromised.Additionally, Always Encrypted with VBS Enclaves provides a number of other benefits. It allows applications to access the data without having to decrypt it, which can improve performance. It also allows applications to access the data without having to be authenticated, which can reduce the administrative overhead associated with authentication. Finally, it allows applications to access the data without needing to have direct access to the database server, which can improve security.
Architecture of Always Encrypted with VBS Enclaves
The architecture of Always Encrypted with VBS Enclaves consists of two components: the database server and the VBS Enclave. The database server is responsible for storing the data, while the VBS Enclave is responsible for encrypting and decrypting the data.The encryption process begins when the application sends a request to the database server. The request contains the data that needs to be encrypted. The database server then sends the data to the VBS Enclave, which encrypts it using the appropriate encryption algorithm. The encrypted data is then stored in the database.
When the application needs to access the data, it sends a request to the database server. The request contains the encrypted data. The database server then sends the encrypted data to the VBS Enclave, which decrypts it using the appropriate decryption algorithm. The decrypted data is then sent back to the application.
Conclusion
In conclusion, Always Encrypted with VBS Enclaves is a powerful security feature of Azure SQL Database that allows data to be encrypted and stored in the database in such a way that it cannot be accessed by the database server, even if the server is compromised. It provides a number of benefits, including improved performance and security, and reduced administrative overhead. The architecture consists of two components: the database server and the VBS Enclave. The database server is responsible for storing the data, while the VBS Enclave is responsible for encrypting and decrypting the data.Popular Questions
