In a move aimed at boosting the security infrastructure, Microsoft is bringingZero Trust DNS(ZTDNS)to Windows devices. Currently in thePrivate Preview,ZTDNSwill soon be available to Windows Insiders.

In theofficial announcement, Microsoft explains howZTDNS, integrated with the Windows DNS(Domain Name System)client and theWindows Filtering Platform (WFP), works.

Elaborating on the next step in the authentication process, Microsoft explains,

In simple words, any network traffic (IPv4andIPv6) to an IP address not a part ofZTDNSwill be blocked. With this, administrators can quickly and securely block traffic whose associated domain names are not identified.

In anotherblog posthighlighting deployment considerations for Windows’Zero Trust DNS, Microsoft highlights that the feature might conflict with printing, file sharing, Windows updates, teleconferencing apps, media streaming, and casting to wireless displays. However, all these can be resolved through some quick modifications!

Microsoft also explains thatZTDNSmight not be as effective when deployed alongsideVPNs,SASE/SSE tunnels, andHyper-V VMs. Besides, anyone withadministrative privileges on the PCcan disable Microsoft’sZero Trust DNSvia the built-in settings. So, admins should reconsider the permissions they grant to users!

There will be several improvements inZero Trust DNSbefore it’s finally introduced in the stable version of Windows, as confirmed by Microsoft.
