This rule identifies when an Azure Virtual Network or Virtual Network Gateway is modified or deleted. This activity is captured through Azure Activity Logs, specifically looking for 'MICROSOFT.NETWORK/VIRTUALNETWORKGATEWAYS/' or 'MICROSOFT.NETWORK/VIRTUALNETWORKS/' operations that end with '/WRITE' or '/DELETE'. Such actions can indicate unauthorized changes to network infrastructure, potentially leading to denial of service, network segmentation bypass, or other security incidents.
