使用快速配置对 Azure SQL 数据库启用漏洞评估
此 PowerShell 脚本支持在 Azure SQL 服务器上快速配置漏洞评估。
如果已使用经典配置来配置漏洞评估，此脚本会将其迁移到快速配置，并复制所有预先存在的基线定义。 扫描历史记录不会复制到新配置。 在经典配置之前使用的存储帐户上，仍可访问扫描历史记录。
先决条件
本示例需要 Azure PowerShell Az 1.0 或更高版本。 运行 Get-Module -ListAvailable Az，查看已安装哪些版本。
如果需要安装，请参阅安装 Azure PowerShell 模块。
通过运行 Connect-AzAccount 登录到 Azure。
如果没有 Azure 订阅，请在开始之前创建一个 Azure 免费帐户。
用户应在存储帐户上具有
Storage Blob Data Reader角色。必须将存储网络设置配置为允许访问执行命令的计算机。
必须具有在脚本使用的工作目录中创建文件夹的权限。
示例脚本 - MigratingToExpressConfiguration.ps1
注意
建议使用 Azure Az PowerShell 模块与 Azure 交互。 若要开始，请参阅安装 Azure PowerShell。 若要了解如何迁移到 Az PowerShell 模块，请参阅 将 Azure PowerShell 从 AzureRM 迁移到 Az。

.SYNOPSIS
This script configured an Azure SQL Server to the express configuration Vulnerability Assessment feature, scans all databases that belong to the selected server and set baselines (if defined in classic configuration) from the storage that is configures in the policy.
.DESCRIPTION
This script migrates Azure SQL Server to express configuration Vulnerability Assessment feature by executing the following steps:
- It deletes the current Vulnerability Assessment settings (if exists).
This step will reset all the Vulnerability Assessment scans and baselines for all databases.
- It copies the current baselines (if exist) from the customer's storage.
In order to revert this script follow the instructions as mentioned here: https://learn.microsoft.com/azure/defender-for-cloud/sql-azure-vulnerability-assessment-manage?tabs=express#revert-back-to-the-classic-configuration.
.PARAMETER ServerSubscriptionId
The Subscription id that the server belongs to
.PARAMETER ServerResourceGroupName
The Resource Group that the server belongs to
.PARAMETER ServerName
The SQL server name that we want to apply the new SQL Vulnerability Assessment policy to.
.PARAMETER Force
Will remove the old Vulnerability Assessment setting without asking for confirmation.
