Migrer depuis les API classiques de Defender pour SQL

Les API Classic Defender for SQL pour l’évaluation des vulnérabilités et l’Protection avancée contre les menaces seront retirées du service le 16 août 2027. Si vous utilisez ces API, migrez vers le modèle de configuration supporté et mettez à jour tout script ou automatisation dépendante avant la date de départ à la retraite.

Cet article explique comment identifier les ressources utilisant les API classiques et migrer la configuration Vulnerability Assessment et Protection avancée contre les menaces.

Modifications de la configuration au niveau de la base de données

Les API classiques prennent en charge la configuration de Vulnerability Assessment et Protection avancée contre les menaces au niveau du serveur ou de la base de données. Les versions API prises en charge utilisent une configuration au niveau du serveur afin que la protection soit appliquée de manière cohérente entre les bases de données du serveur.

Ce changement n'affecte pas la facturation car les frais de Microsoft Defender pour SQL sont basés sur des serveurs protégés plutôt que sur des paramètres individuels de base de données.

Identifier les ressources à l’aide d’API classiques

Utilisez AuditClassicPolicies.ps1 pour identifier les ressources Azure SQL qui utilisent les API classiques Vulnerability Assessment ou Protection avancée contre les menaces.

Le script vérifie :

Serveurs logiques Azure SQL Database
Instances managées Azure SQL
espaces de travail Azure Synapse Analytics

Le script est en lecture seule et ne modifie pas la configuration des ressources.

Prerequisites

Avant de lancer le script, assurez-vous d’avoir :

PowerShell 7 ou version ultérieure.
Azure PowerShell Az.Accounts module version 2.9.1 ou ultérieure.
Au minimum, un accès Lecteur à l’abonnement que vous souhaitez auditer.

Pour installer ou mettre à jour le Az.Accounts module, exécutez :

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

Vous n’avez pas besoin de lancer Connect-AzAccount avant d’avoir lancé le script. Si vous n’êtes pas déjà connecté, le script vous invite à vous connecter.

Exécutez le script d’audit

Copiez AuditClassicPolicies.ps1 depuis la section suivante et enregistrez-le localement sous le nom de AuditClassicPolicies.ps1.
Exécutez le script :
```
.\AuditClassicPolicies.ps1
```
Si vous n’êtes pas connecté, le script vous invite à vous connecter. Si votre compte a accès à plusieurs abonnements, sélectionnez celui que vous souhaitez auditer.

Pour auditer un abonnement spécifique, exécutez :

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

Par défaut, le script affiche les progrès et un résumé final.

Examiner les résultats de l’audit

Le script indique le nombre de ressources scannées, celles qui n’utilisent pas d’API classiques, et celles nécessitant une migration.

Si les ressources concernées sont trouvées, le script crée un rapport CSV qui ne contient que les ressources nécessitant une action. Si aucune ressource affectée n’est trouvée, aucun rapport CSV n’est créé.

Le rapport CSV contient les informations suivantes :

Column	Description
`SubscriptionId`	Abonnement contenant la ressource.
`ServerName`	Nom du serveur SQL, de l’instance SQL Managed Instance ou de l’espace de travail Synapse.
`ResourceType`	Type de ressource.
`ResourceGroup`	Groupe de ressources qui contient la ressource.
`ServerLevelClassicVaPolicy`	Indique si l’évaluation classique des vulnérabilités est configurée au niveau serveur ou espace de travail.
`ServerLevelClassicAtpPolicy`	Indique si le classique Protection avancée contre les menaces est configuré au niveau serveur ou espace de travail.
`DbLevelVaPolicy`	Indique si une base de données ou un pool SQL utilise la configuration classique d’évaluation des vulnérabilités.
`DbLevelAtpPolicy`	Indique si une base de données ou un pool SQL utilise la configuration classique Protection avancée contre les menaces.
`DatabasesWithVaPolicy`	Bases de données ou pools SQL utilisant la configuration classique d’évaluation des vulnérabilités.
`DatabasesWithAtpPolicy`	Bases de données ou pools SQL utilisant la configuration classique Protection avancée contre les menaces.

<#
.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
    whether to migrate.

    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.

.EXAMPLE

Migrer la configuration d’Protection avancée contre les menaces

Certaines propriétés de configuration disponibles dans les API classiques Protection avancée contre les menaces ne sont pas disponibles dans l'API prise en charge. Utilisez les alternatives suivantes pour ces capacités :

Capacité	Propriété API classique	Alternatif
Désactivez les alertes spécifiques	`properties.disabledAlerts`	Supprimer les alertes de Microsoft Defender pour le cloud
Notifications par e-mail	`properties.emailAccountAdmins`, `properties.emailAddresses`	Configurer des notifications par e-mail pour les alertes de sécurité
Exportation des alertes vers le stockage	`properties.retentionDays`, `properties.storageAccountAccessKey`, `properties.storageEndpoint`	Utilisez l’exportation continue et, en option, exportez les données des Event Hubs vers stockage Azure.

Pour la configuration classique Protection avancée contre les menaces au niveau de la base de données, les scripts de migration de cette section activent la protection au niveau serveur ou espace de travail avant de désactiver la configuration au niveau de la base de données.

Les scripts ne modifient pas la configuration de l’évaluation des vulnérabilités.

Important

Les scripts de migration modifient les ressources Azure. Assurez-vous d’avoir les autorisations nécessaires pour mettre à jour les ressources que vous migrez.

Migrer une seule ressource

À utiliser Remediate-ClassicAtpPolicy.ps1 pour migrer la configuration Protection avancée contre les menaces au niveau de la base de données pour un serveur SQL, une instance SQL Managed Instance ou un espace de travail Synapse.

Copiez le Remediate-ClassicAtpPolicy.ps1 script dans la section suivante et enregistrez-le localement sous Remediate-ClassicAtpPolicy.ps1forme .
Exécutez le script et spécifiez l’abonnement, le type de ressource, le nom de la ressource et le groupe de ressources :
```
.\Remediate-ClassicAtpPolicy.ps1 -SubscriptionId "<subscription-ID>" -ResourceType <resource-type> -ResourceName "<resource-name>" -ResourceGroup "<resource-group>"
```
Pour ResourceType, utilisez SqlServer, SqlManagedInstance ou Synapse.

Le script permet d’abord la protection au niveau du serveur ou de l’espace de travail. Il désactive la configuration classique Protection avancée contre les menaces au niveau de la base de données seulement après activation réussie de la protection au niveau serveur.

.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.

.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.

Migrer la configuration de l’évaluation des vulnérabilités

Migrez les ressources utilisant la configuration classique d’évaluation des vulnérabilités vers Express Configuration.

Lorsque vous migrez, notez les différences suivantes :

Capacité	Configuration classique	Configuration rapide
Notifications par e-mail	Planificateur intégré et applications logiques	Applications logiques
Exportation de l’analyse	Excel	CSV
les API	API séparées pour chaque type de ressource SQL	API unifiée à travers Azure SQL Database, Azure SQL Managed Instance, SQL Server sur les machines virtuelles Azure, et Azure Synapse Analytics

Express Configuration prend en charge le reporting par email via Logic Apps. Le mécanisme de planification intégré disponible avec la configuration classique n’est pas pris en charge. Pour plus d’informations, voir Automatiser les notifications par e-mail avec Logic Apps.

Express Configuration exporte les résultats de l’évaluation des vulnérabilités au format CSV au lieu d’Excel.

Express Configuration fournit une API unifiée entre les types de ressources SQL pris en charge. Pour plus d’informations, voir Gérer les évaluations de vulnérabilités de façon programmatique.

Pour les étapes de migration et le script de migration PowerShell, voir Migrer l’évaluation des vulnérabilités SQL vers Express Configuration.
