name: Azure Update Security Policy Alert Not Configured
|
|
author: princechaddha
|
|
severity: high
|
|
description: |
|
|
Ensure that an Azure activity log alert is used to detect "Update Security Policy" events within your Microsoft Azure cloud account. Activity log alerts get activated when a new activity log event that matches the condition specified in the alert occurs. In this case, the required alert condition is 'Whenever the Security Activity Log "Update security policy (Microsoft.Security/policies)" has "any" level, with "any" status and event is initiated by "any"'.
|
|
impact: |
|
|
Without proper alert rules configured for monitoring "Update Security Policy" events, unauthorized or unanticipated policy changes might go unnoticed, leading to potential security risks.
|
|
remediation: |
|
|
Ensure alert rules are properly configured to monitor and notify on "Update Security Policy" events by setting the alert condition to "Microsoft.Security/policies/write" and ensuring that an action group is attached to manage notifications.
