Verify that Activity Log Alert exists for Create or Update Security Solution

Last updated: April 9, 2026

Subtitle: Framework Reference: A.8.16 Integration: Azure Monitor Activity Logs

Why this matters

Security solutions are central to maintaining a secure cloud environment. If they are created or updated without oversight, it opens the door to undetected misconfigurations or malicious changes. This alert ensures that any modification to security solutions triggers immediate visibility and review.

What this check does

This Auto Check verifies that an Activity Log Alert is configured for the event:

Operation name = Microsoft.Security/securitySolutions/write 

Check Logic:

IF Activity Log Alert EXISTS AND   Condition includes Operation name = 'Microsoft.Security/securitySolutions/write' AND   Category = 'Administrative' AND   No filters on Level, Status, or Caller THEN PASS ELSE FAIL

The check ensures that such an alert is enabled and linked to an action group to notify responsible personnel.

How to fix it

  1. Remediate via Azure Portal

  2. Go to Monitor > Alerts > Alert Rules

  3. Click Create → Alert rule

  4. Select your Subscription

  5. Under Condition, click See all signals

  6. Select: Create or Update Security Solutions (Security Solutions)

  7. Under Actions, assign an existing Action Group or create a new one

  8. Under Details, provide a name and resource group

  9. Review + Create → Create

  10. Remediate via Azure CLI

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