Pipeline: 3.1.16 [LEGACY] Ensure That Microsoft Defender for DNS Is Set To 'On'

Description

[NOTE: As of August 1, 2023 customers with an existing subscription to Defender for DNS can continue to use the service, but new subscribers will receive alerts about suspicious DNS activity as part of Defender for Servers P2.]

Microsoft Defender for DNS scans all network traffic exiting from within a subscription.

DNS lookups within a subscription are scanned and compared to a dynamic list of websites that might be potential security threats. These threats could be a result of a security breach within your services, thus scanning for them could prevent a potential security threat from being introduced.

  2. Under Management, select Environment Settings.
  3. Click on the subscription name.
  4. Select the Defender plans blade.
  5. Select On under Status for DNS.

az security pricing create -n 'DNS' --tier 'Standard'

From Powershell
