Azure security baseline for Microsoft Azure Attestation
Članak
This security baseline applies guidance from the Microsoft cloud security benchmark version 1.0 to Microsoft Azure Attestation. The Microsoft cloud security benchmark provides recommendations on how you can secure your cloud solutions on Azure. The content is grouped by the security controls defined by the Microsoft cloud security benchmark and the related guidance applicable to Microsoft Azure Attestation.
You can monitor this security baseline and its recommendations using Microsoft Defender for Cloud. Azure Policy definitions will be listed in the Regulatory Compliance section of the Microsoft Defender for Cloud portal page.
When a feature has relevant Azure Policy Definitions, they are listed in this baseline to help you measure compliance with the Microsoft cloud security benchmark controls and recommendations. Some recommendations may require a paid Microsoft Defender plan to enable certain security scenarios.

Feature notes: The user creating an attestation provider should have sufficient access levels on the subscription to create a resource (e.g: owner/contributor).
Configuration Guidance: Use Azure role-based access control (Azure RBAC) to manage Azure resource access through built-in role assignments. Azure RBAC roles can be assigned to users, groups, service principals, and managed identities.
Note: Once an attestation provider is created in this resource group, an Azure AD user must have Attestation Contributor role on the provider to perform operations like policy configuration/ policy signer certificates management. These permissions can also be inherited with roles such as Owner (wildcard permissions)/ Contributor (wildcard permissions) on the subscription/ resource group.

Feature notes: Customers can enable logging using powershell commands or log analytics feature in portal .
Configuration Guidance: Enable resource logs for the service. For example, Key Vault supports additional resource logs for actions that get a secret from a key vault or and Azure SQL has resource logs that track requests to a database. The content of resource logs varies by the Azure service and resource type.
Explore network traffic filtering with Network Security Group, set up Microsoft Defender for Cloud, create a Log Analytics workspace, configure Log Analytics agent integration, Azure Key Vault networking, and connect an Azure SQL server using Azure Private Endpoint in the Azure portal. Enhance cloud security effectively. (SC-5002)
