From Azure CLI

az monitor activity-log alert create --resource-group "<resource group name>" --condition category=Administrative and operationName=Microsoft.Security/securitySolutions/write and level=<verbose | information | warning | error | critical> --scope "/subscriptions/<subscription ID>" --name "<activity log rule name>" --subscription <subscription id> --action-group <action group ID>

From PowerShell

Create the Conditions object.

$conditions = @()
$conditions += New-AzActivityLogAlertAlertRuleAnyOfOrLeafConditionObject -Equal Administrative -Field category
$conditions += New-AzActivityLogAlertAlertRuleAnyOfOrLeafConditionObject -Equal Microsoft.Security/securitySolutions/write -Field operationName
$conditions += New-AzActivityLogAlertAlertRuleAnyOfOrLeafConditionObject -Equal Verbose -Field level

Retrieve the Action Group information and store in a variable, then create the Actions object.

$actionGroup = Get-AzActionGroup -ResourceGroupName <resource group name> -Name <action group name>
$actionObject = New-AzActivityLogAlertActionGroupObject -Id $actionGroup.Id

Create the Scope object

$scope = "/subscriptions/<subscription ID>"

Create the Activity Log Alert Rule for Microsoft.Security/securitySolutions/write

New-AzActivityLogAlert -Name "<activity log alert rule name>" -ResourceGroupName "<resource group name>" -Condition $conditions -Scope $scope -Location global -Action $actionObject -Subscription <subscription ID> -Enabled $true
