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.
