Configures auditing against a CIS Benchmark item.

Level: 2

[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.
