Implementation Guidance for Key Security Controls¶

Network Security Implementation¶

Private Link and Private Endpoints¶

Configure private endpoints for secure connectivity:

# PowerShell: Create private endpoint for Synapse workspace
$workspace = Get-AzSynapseWorkspace -Name "mysynapseworkspace" -ResourceGroupName "myresourcegroup"

New-AzPrivateEndpoint `
  -ResourceGroupName "myresourcegroup" `
  -Name "synapse-sql-endpoint" `
  -Location "eastus" `
  -Subnet $subnet `
  -PrivateLinkServiceConnection @{
    Name = "synapse-sql-connection"
    PrivateLinkServiceId = $workspace.Id
    GroupId = "Sql"
  }

Managed Virtual Network¶

Enable managed virtual network during workspace creation:

# PowerShell: Create Synapse workspace with managed VNet
New-AzSynapseWorkspace `
  -ResourceGroupName "myresourcegroup" `
  -Name "mysynapseworkspace" `
  -Location "eastus" `
  -DefaultDataLakeStorageAccountName "mystorageaccount" `
  -DefaultDataLakeStorageFilesystem "myfilesystem" `
  -SqlAdministratorLoginCredential (Get-Credential) `
  -ManagedVirtualNetwork "default" `
  -AllowAllConnections $false

IP Firewall Rules¶

Configure IP firewall rules:

# PowerShell: Add IP firewall rule to Synapse workspace
$synapse = Get-AzSynapseWorkspace -Name "mysynapseworkspace" -ResourceGroupName "myresourcegroup"

$firewallRuleName = "AllowedIpRange"
$startIpAddress = "192.168.0.0"
$endIpAddress = "192.168.0.255"

Update-AzSynapseFirewallRule `
  -WorkspaceName $synapse.Name `
  -Name $firewallRuleName `
  -StartIpAddress $startIpAddress `
  -EndIpAddress $endIpAddress

Identity and Access Control Implementation¶

RBAC Role Assignment¶

Implement least-privilege access with RBAC:

# PowerShell: Assign Synapse RBAC roles
$userObjectId = "00000000-0000-0000-0000-000000000000" # Replace with actual Object ID
$workspaceName = "mysynapseworkspace"
$roleId = "6e4bf58a-b8e1-4cc3-bbf9-d73143322b78" # Synapse Sql Administrator role

New-AzSynapseManagedIdentitySqlControlSettings `
  -WorkspaceName $workspaceName `
  -ResourceGroupName "myresourcegroup" `
  -GrantSqlControlToManagedIdentity "Enabled"

New-AzSynapseRoleAssignment `
  -WorkspaceName $workspaceName `
  -RoleId $roleId `
  -ObjectId $userObjectId

SQL Active Directory Admin¶

Configure Azure AD authentication for SQL:

# PowerShell: Set Azure AD admin for SQL pool
$username = "username@domain.com" # Replace with actual admin username
$objectId = "00000000-0000-0000-0000-000000000000" # Replace with actual Object ID

Set-AzSynapseSqlActiveDirectoryAdministrator `
  -WorkspaceName "mysynapseworkspace" `
