6.6 Ensure that Network Watcher is 'Enabled' (includes Reserved access regions) (Automated)


This rule has been changed to automated, see Automated Policies for CIS Azure 1.5.0 for details.

Profile Applicability

• Level 2


Enable Network Watcher for physical regions in Azure subscriptions.


Network diagnostic and visualization tools available with Network Watcher help users understand, diagnose, and gain insights to the network in Azure.


There are additional costs per transaction to run and store network data. For high-volume networks these charges will add up quickly.


From Azure Portal

  1. Go to Network Watcher.
  2. Ensure that a network watcher is listed for each region.

From Azure CLI

az network watcher list --query "[].{Location:location,State:provisioningState}" -o table

This will list all network watchers and their provisioning state. Ensure provisioningState is Succeeded for each network watcher.

az account list-locations --query "[?metadata.regionType=='Physical'].{Name:name,DisplayName:regionalDisplayName}" -o table

This will list all physical regions that exist in the subscription. Compare this list to the previous one to ensure that for each region, a network watcher exists with provisioningState set to Succeeded.

From Azure Powershell

Get a list of Network Watchers


Make sure each watcher is set with the ProvisioningState setting set to Succeeded.


Opting out of Network Watcher automatic enablement is a permanent change. Once you opt-out you cannot opt-in without contacting support.

To manually enable Network Watcher in each region where you want to use Network Watcher capabilities, follow the steps below.

From Azure Portal

  1. Go to Network Watcher.
  2. Click Create.
  3. Select a Region from the drop-down menu.
  4. Click Add.

From Azure CLI
