Description

Create an Activity Log Alert for the Create or Update Network Security Group event.

Rationale

Monitoring for Create or Update Network Security Group events gives insight into network access changes and may reduce the time it takes to detect suspicious activity.

Audit

This policy evaluates Azure Subscriptions for the presence of an Azure Activity Log Alert that captures Create or Update Network Security Group events. A subscription is marked as INCOMPLIANT if it does not have an Activity Log Alert whose Condition JSON filters on the Microsoft.Network/networkSecurityGroups/write operation.

Default Value

By default, no monitoring alerts are created.
