Migrar do Defender clássico para APIs SQL

O Classic Defender for SQL APIs para Avaliação de Vulnerabilidades e Proteção Avançada contra Ameaças será descontinuado em 16 de agosto de 2027. Se você usar essas APIs, migre para o modelo de configuração suportado e atualize quaisquer scripts dependentes ou automação antes da data de aposentadoria.

Este artigo explica como identificar recursos que utilizam as APIs clássicas e migrar a configuração Vulnerability Assessment e Proteção Avançada contra Ameaças.

Alterações na configuração em nível de banco de dados

As APIs Classic suportam a configuração do Vulnerability Assessment e do Proteção Avançada contra Ameaças tanto no nível do servidor quanto do banco de dados. As versões da API suportadas usam configuração em nível de servidor para que a proteção seja aplicada de forma consistente entre os bancos de dados do servidor.

Essa mudança não afeta a faturação porque as cobranças do Microsoft Defender para SQL são baseadas em servidores protegidos, e não em configurações individuais de banco de dados.

Identificar recursos usando APIs clássicas

Use AuditClassicPolicies.ps1 para identificar recursos SQL do Azure que utilizam APIs clássicas de Vulnerability Assessment ou Proteção Avançada contra Ameaças.

O roteiro verifica:

• Servidores lógicos do Banco de Dados SQL do Azure
• Instâncias Gerenciadas de SQL do Azure
• Espaços de trabalho do Azure Synapse Analytics

O script é somente leitura e não altera a configuração dos recursos.

Prerequisites

Antes de executar o script, certifique-se de ter:

• PowerShell 7 ou posterior.
• módulo Azure PowerShell Az.Accounts versão 2.9.1 ou posterior.
• Pelo menos acesso de leitor à assinatura que você deseja auditar.

Para instalar ou atualizar o Az.Accounts módulo, execute:

Install-Module Az.Accounts -Scope CurrentUser -MinimumVersion 2.9.1

Você não precisa correr Connect-AzAccount antes de executar o script. Se você ainda não está logado, o script pede para você fazer login.

Execute o script de auditoria

1. Copie AuditClassicPolicies.ps1 da seção seguinte e salve localmente como AuditClassicPolicies.ps1.

2. Executar o script:

   .\AuditClassicPolicies.ps1
   

   Se você não estiver logado, o script pede para você fazer login. Se sua conta tem acesso a várias assinaturas, selecione a assinatura que deseja auditar.

3. Para auditar uma assinatura específica, execute:

   .\AuditClassicPolicies.ps1 -SubscriptionId "<subscription-ID>"
   

Por padrão, o roteiro exibe o progresso e um resumo final.

Revise os resultados da auditoria

O script informa o número de recursos escaneados, o número que não usa APIs clássicas e o número que requer migração.

Se recursos afetados forem encontrados, o script cria um relatório CSV que contém apenas os recursos que requerem ação. Se nenhum recurso afetado for encontrado, nenhum relatório CSV é criado.

O relatório CSV contém as seguintes informações:

.SYNOPSIS
    Audits a subscription for usage of the classic SQL Vulnerability Assessment
    and Advanced Threat Protection (ATP) APIs across SQL Server, SQL Managed Instance, and Synapse.

.DESCRIPTION
    For the given subscription, discovers all:
      - Azure SQL logical servers   (Microsoft.Sql/servers)
      - SQL Managed Instances       (Microsoft.Sql/managedInstances)
      - Synapse workspaces          (Microsoft.Synapse/workspaces)

    Synapse's own auto-provisioned backing SQL server (kind contains "analytics", living in a
    system "synapseworkspace-managedrg-*" resource group) is excluded from the SQL Server list
    - it is not a customer-managed resource and is already covered via the Synapse workspace
    entry itself.

    For each resource, this script checks whether the Classic APIs are still
    configured (i.e. return a real, non-default policy):
      - Classic VA policy               (.../vulnerabilityAssessments/default)
      - Classic Security Alert Policy   (.../securityAlertPolicies/Default) - the classic
        ATP API (NOT the newer advancedThreatProtectionSettings API). A policy is treated as
        "configured" only if it shows a concrete configuration signal: a storage endpoint is
        set, real notification email addresses are set, emailAccountAdmins is on, or specific
        alert categories are disabled. `state == Enabled` alone is NOT sufficient - Defender for
        SQL can report state=Enabled even when the classic policy was never actively used.

    It then enumerates all child databases / SQL pools and checks the same two policies at
    the database level, recording which specific databases have a Classic VA and/or Classic
    Security Alert Policy configured.

    These are exactly the API surfaces listed for deprecation:
      VA:  Server/DB Vulnerability Assessments, Baselines, Scans (SQL DB, MI, Synapse)
      ATP: Server/DB Security Alert Policies (SQL DB, MI, Synapse)

    No changes are made - this script is read-only. The CSV report only includes resources
    that need attention (a Classic VA and/or ATP policy configured somewhere, at the
    server/workspace level or a database/pool level) - fully clean resources are omitted from
    the report but included in the console summary count.

.PARAMETER SubscriptionId
    The subscription to audit (GUID or subscription name). If you don't know it, run this
    script without the parameter set and it will prompt you to sign in and pick one.

.PARAMETER OutputPath
    Path to the CSV report. Defaults to
    ".\ClassicPolicyAudit_<subscriptionId>_<yyyyMMdd_HHmmss>.csv" in the current directory.

.PARAMETER ShowDetails
    Show a verbose, per-resource trace of every check performed (useful for troubleshooting).
    By default the script only prints a compact progress bar and a final summary.

.EXAMPLE
    .\AuditClassicPolicies.ps1 -SubscriptionId "aaaaaaaa-bbbb-cccc-dddd-eeeeeeeeeeee"

.EXAMPLE
    .\AuditClassicPolicies.ps1 -SubscriptionId "aaaaaaaa-bbbb-cccc-dddd-eeeeeeeeeeee" -OutputPath "C:\reports\audit.csv"

.NOTES
    This script is READ-ONLY - it only performs GET requests and never modifies any resource.
    You need at least Reader access on the subscription to run it.

.SYNOPSIS
    Shows the current (classic) Security Alert Policy / Advanced Threat Protection
    configuration for a SQL Server, SQL Managed Instance, or Synapse workspace - at the
    SERVER/WORKSPACE level.

.DESCRIPTION
    Read-only. Retrieves and displays the raw Security Alert Policy settings (state, storage
    endpoint, notification email addresses, email account admins, disabled alert categories)
    for the given resource, so you can see exactly what is currently configured before deciding

.SYNOPSIS
    Shows the current (classic) Security Alert Policy configuration for a single DATABASE
    (or Synapse SQL pool), i.e. the per-database Advanced Threat Protection override.

.DESCRIPTION
    Read-only. Retrieves and displays the raw Security Alert Policy settings (state, storage
    endpoint, notification email addresses, email account admins, disabled alert categories)
    for the given database / SQL pool, so you can see exactly what is currently configured
    before deciding whether to migrate or remove the per-database override.

    This does not change anything.

.PARAMETER SubscriptionId
    The subscription containing the resource. If omitted, you'll be prompted to sign in and
    pick one.

.PARAMETER ResourceType
    One of: SqlServer, SqlManagedInstance, Synapse.

.PARAMETER ResourceName
    The name of the server / managed instance / Synapse workspace.

.PARAMETER ResourceGroup
    The resource group containing the resource.

.PARAMETER DatabaseName
    The database name (or SQL pool name, for Synapse).

Migrar configuração do Proteção Avançada contra Ameaças

Algumas propriedades de configuração disponíveis nas APIs clássicas do Proteção Avançada contra Ameaças não estão disponíveis na API suportada. Use as seguintes alternativas para essas capacidades:

Para a configuração clássica do Proteção Avançada contra Ameaças em nível de banco de dados, os scripts de migração nesta seção habilitam a proteção no nível do servidor ou espaço de trabalho antes de desativar a configuração em nível de banco de dados.

Os scripts não modificam a configuração da Avaliação de Vulnerabilidades.

Migre um único recurso

Use o Remediate-ClassicAtpPolicy.ps1 para migrar a configuração do Proteção Avançada contra Ameaças no nível do banco de dados de um único servidor SQL, Instância Gerenciada de SQL ou espaço de trabalho do Synapse.

1. Copie o Remediate-ClassicAtpPolicy.ps1 script na seção seguinte e salve-o localmente como Remediate-ClassicAtpPolicy.ps1.

2. Execute o script e especifique a assinatura, tipo de recurso, nome do recurso e grupo de recursos:

   .\Remediate-ClassicAtpPolicy.ps1 -SubscriptionId "<subscription-ID>" -ResourceType <resource-type> -ResourceName "<resource-name>" -ResourceGroup "<resource-group>"
   

   Para ResourceType, use SqlServer, SqlManagedInstance ou Synapse.

O script primeiro permite a proteção no nível do servidor ou do espaço de trabalho. Ele desativa a configuração clássica Proteção Avançada contra Ameaças em nível de banco de dados somente após a habilitação da proteção em nível de servidor com sucesso.

<#
.SYNOPSIS
    Remediates the classic Advanced Threat Protection
    configuration for a SINGLE Azure SQL resource (SQL Server, SQL Managed Instance, or
    Synapse workspace).

.DESCRIPTION
    Only acts on resources that have a DATABASE-LEVEL Classic Security Alert Policy actually
    configured. If none is found, the script does nothing.

    When a database-level Classic ATP policy is found:
      1. Enables the new server-level Advanced Threat Protection setting:
           - SQL Server / SQL Managed Instance: the new `advancedThreatProtectionSettings` API
             (state = Enabled). This new API only supports on/off - it does not support
             storage/email configuration.
           - Synapse workspace: the new API is not supported for Synapse, so the classic
             Security Alert Policy is set at the WORKSPACE level instead, with only
             `state = Enabled` (no storage/emails set).
      2. Once the server-level setting succeeds, disables (state = Disabled) every
         database-level Classic Security Alert Policy that was found, so the database no
         longer relies on the classic per-database policy.

    This script does NOT touch Vulnerability Assessment (VA) settings at all - only ATP/
    Security Alert Policy.

    Every write to Azure is retried up to 3 times with a short delay before being reported as
    failed. If the server-level setting fails after retries, the old database-level policies
    are intentionally left untouched (so there is no gap where nothing is protecting the
    database) and the failure is reported so you can re-run the script later.

.PARAMETER SubscriptionId
    The subscription containing the resource.

.PARAMETER ResourceType
    One of: SqlServer, SqlManagedInstance, Synapse.

.PARAMETER ResourceName
    The name of the server / managed instance / Synapse workspace.

.PARAMETER ResourceGroup
    The resource group containing the resource.

.PARAMETER ShowDetails
    Show a verbose, per-step trace of every check/write performed.

.EXAMPLE
    .\Remediate-ClassicAtpPolicy.ps1 -SubscriptionId "aaaa-bbbb-cccc-dddd" -ResourceType SqlManagedInstance -ResourceName testmig-sqlmi -ResourceGroup TestMigrationScript

.NOTES
    This script WRITES to Azure resources. Make sure you have Security Admin / SQL Security
    Manager (or Contributor) rights on the target resource before running it.

Migre recursos em uma assinatura

Use Remediate-ClassicAtpPolicySubscription.ps1 para identificar e migrar recursos com a configuração clássica da Proteção Avançada contra Ameaças no nível do banco de dados em toda a assinatura.

1. Copie o Remediate-ClassicAtpPolicySubscription.ps1 script na seção seguinte e salve-o localmente como Remediate-ClassicAtpPolicySubscription.ps1.

2. Executar o script:

   .\Remediate-ClassicAtpPolicySubscription.ps1 -SubscriptionId "<subscription-ID>"
   

O script verifica os servidores SQL, as Instâncias Gerenciadas do SQL e os espaços de trabalho do Synapse na assinatura e migra os recursos que têm configuração clássica de Proteção Avançada contra Ameaças no nível do banco de dados.

.SYNOPSIS
    Remediates the classic Advanced Threat Protection
    configuration across an ENTIRE subscription, for every SQL Server, SQL Managed Instance,
    and Synapse workspace that has a database-level Classic ATP policy configured.

.DESCRIPTION
    Discovers all SQL servers, SQL Managed Instances, and Synapse workspaces in the given
    subscription (using the same discovery/filtering rules as AuditClassicPolicies.ps1,
    including exclusion of Synapse's auto-provisioned backing SQL server). For each one:

      - Skips it entirely if it has no database-level Classic Security Alert Policy configured.
      - Otherwise, remediates it exactly like Remediate-ClassicAtpPolicy.ps1 does:
          1. Enables the new server-level Advanced Threat Protection setting
             (SQL Server / Managed Instance), or the classic Security Alert Policy at the
             workspace level with state=Enabled only (Synapse - new API not supported there).
          2. Disables (state = Disabled) each database-level Classic Security Alert Policy that
             was found, once the server-level setting succeeds.

    This script does NOT touch Vulnerability Assessment (VA) settings at all - only ATP/
    Security Alert Policy. Resources with only a server-level classic policy (and no
    database-level override) are left untouched, since the task here is specifically to clean
    up per-database overrides in favor of a single server-level setting.

    Every write to Azure is retried up to 3 times with a short delay before being reported as
    failed. A resource-level failure does not stop the run - the script keeps going and reports
    every success/failure at the end so you know exactly what to re-run.

.PARAMETER SubscriptionId
    The subscription to remediate. If omitted, you'll be prompted to sign in and pick one.

.PARAMETER OutputPath
    Path to the result CSV - one row per remediated resource (SubscriptionId, ServerName,
    ResourceType, ResourceGroup, DatabasesRemediated, Status, Detail). Resources with no Classic
    ATP policy found are NOT included in the CSV (they're still shown in the console trace when
    -ShowDetails is used). Defaults to
    ".\ClassicAtpRemediation_<subscriptionId>_<yyyyMMdd_HHmmss>.csv" in the current directory.

.PARAMETER ShowDetails
    Show a verbose, per-resource/per-step trace while it runs.

.EXAMPLE
    .\Remediate-ClassicAtpPolicySubscription.ps1 -SubscriptionId "aaaa-bbbb-cccc-dddd"

.NOTES
    This script WRITES to Azure resources across the whole subscription. Make sure you have
    Security Admin / SQL Security Manager (or Contributor) rights before running it. Consider
    running Remediate-ClassicAtpPolicy.ps1 against a single test resource first.

Migração da configuração de Avaliação de Vulnerabilidades

Migre recursos que usem a configuração clássica de Avaliação de Vulnerabilidades para Express Configuration.

Ao migrar, note as seguintes diferenças:

O Express Configuration suporta relatórios de e-mail por meio do Logic Apps. O mecanismo de agendamento embutido disponível na configuração clássica não é suportado. Para mais informações, veja Automatizar notificações por e-mail com Logic Apps.

O Express Configuration exporta os resultados da avaliação de vulnerabilidades em formato CSV em vez de Excel.

O Express Configuration fornece uma API unificada entre os tipos de recursos SQL suportados. Para mais informações, veja Gerenciar avaliações de vulnerabilidades programáticamente.

Para etapas de migração e o script de migração do PowerShell, veja Migrar avaliação de vulnerabilidades SQL para Express Configuration.
