Introduction to Azure Data Explorer
Azure Data Explorer (ADX) is a fully managed Azure service designed for running analytics on large volumes of data. It is specifically optimized for interactive ad-hoc queries and is commonly used for analyzing time series data. ADX supports structured, semi-structured, and unstructured data, making it a versatile tool for extracting key insights from diverse datasets. With its high speed data ingestion options and support for machine learning, ADX enables users to analyze petabytes of information in just seconds.
The Importance of Confidential Computing
Confidential computing adds an extra layer of security to Azure Data Explorer by encrypting data stored in the virtual machine's memory. While most organizations already encrypt data at rest and in transit, encrypting data in memory is often overlooked. Azure Confidential Computing addresses this gap by utilizing AMD EPYC SEV-SNP technologies. These technologies provide advanced security features such as Secure Encrypted Virtualization (SEV) and Secure Nested Paging (SNP). By encrypting data in memory, confidential computing protects against unauthorized access and enhances data security.
Encryption Technologies in Organizations
Most organizations already implement encryption technologies to protect their data. This includes encrypting data at rest (stored on disk) and data in transit (using protocols like TLS). However, the encryption of data in a virtual machine's memory is often missing. Azure Confidential Computing fills this gap by encrypting all data in memory using SEV-SNP technologies. This ensures end-to-end data protection and prevents unauthorized access to sensitive information.
Overview of Azure Confidential Computing
Azure Confidential Computing is a security feature that leverages AMD EPYC SEV-SNP technologies to provide advanced protection for virtualized environments. SEV stands for Secure Encrypted Virtualization and encrypts data in a virtual machine's memory, preventing unauthorized access when it is stored or transmitted. SNP, on the other HAND, enables a hierarchical paging model that only allows the virtual machine's administrator to access its memory. These technologies create isolated memory regions within each virtual machine, ensuring data privacy and security.
Understanding AMD EPYC SEV-SNP Technologies
AMD EPYC SEV-SNP technologies are the foundation of Azure Confidential Computing in ADX. SEV-SNP provides secure encrypted virtualization and encrypts all data in a virtual machine's memory when it is saved to disk or transmitted over a network. This technology prevents unauthorized access to the VM's data, protecting it from malicious actors. SNP, or Secure Nested Paging, supports a hierarchical paging model that allows only the administrator of a virtual machine to access its memory. Together, these technologies establish a secure boot process and isolate the memory of each virtual machine.
Use Cases for Confidential Computing in ADX
Confidential computing in Azure Data Explorer offers several key use cases. Firstly, it provides protection from malicious virtual machines hosted on the same machine. By isolating the memory of each VM, confidential computing ensures that actors within one VM cannot access the memories of other VMs. Secondly, it protects virtual machines from malicious behavior of hypervisor or cloud administrators. With confidential computing, these administrators do not have access to the memory of virtual machines, preventing unauthorized data access or execution of malicious code. Lastly, confidential computing safeguards against physical attacks by encrypting the VM's memory. This means that even with physical access to the host machine, an attacker cannot read the memory of a virtual machine.
Compliance Requirements and Confidential Computing
Azure Confidential Computing is particularly crucial for meeting compliance requirements such as those mandated by GDPR and HIPAA. The encryption of data in a virtual machine's memory through SEV-SNP technologies ensures that highly confidential data is protected. Companies operating in highly regulated sectors, such as the financial and Healthcare industries, can benefit greatly from the enhanced security provided by confidential computing.
Deploying a Confidential ADX Cluster
Creating a confidential Azure Data Explorer cluster is a simple process. During cluster creation, you can select the ECasv5 SKU family, which offers confidential computing capabilities. Alternatively, if you wish to migrate an existing ADX cluster to a confidential SKU, you can select a confidential computing SKU as the target SKU. no code changes are required for this migration, making it a straightforward lift and shift experience. The deployment can be done through either the Azure portal or using Azure Resource Manager (ARM).
Targeted Verticals for Confidential Computing
Confidential computing in ADX is particularly targeted towards the financial sector, which has strict compliance regulations regarding the storage of highly confidential data. However, any organization handling highly sensitive data, such as government agencies or healthcare companies, can greatly benefit from the advanced security offered by confidential computing technologies.
Demo: Creating a Confidential ADX Cluster
In this demo, we will walk you through the process of creating an ADX Confidential Computing Cluster using the Azure portal. We will also demonstrate how to configure the cluster to use a customer managed key (CMK) for encryption. Prior to creating the cluster, it is necessary to have a Key Vault and assign it a user managed identity. The process involves selecting a resource group, choosing a region that supports confidential SKUs, and selecting a confidential SKU for the cluster. Following cluster creation, we will enable customer managed key encryption and assign a user managed identity to the cluster. This demo showcases the ease of creating a confidential ADX cluster with enhanced data encryption.
