Microsoft has announced that Zero Trust DNS (ZTDNS), which aims to restrict device access to untrusted domains in Windows, is currently in private preview.
In a blog post announcing the private preview, Microsoft stated that ZTDNS was crafted with interoperability in mind, leveraging network protocols from open standards to meet Zero Trust criteria outlined in OMB M-22-09 and NIST SP 800-207. This solution will provide an option to administrators seeking to utilize domain names as indicators of network traffic.
Per Microsoft:
In the blog post, Microsoft’s Tommy Jensen, of the Windows Core Networking team, breaks down exactly how ZTDNS will work:
While the new feature will help to block incoming attacks on certain devices, Microsoft said that ZTDNS in its current early state still has some shortcomings. Because of networking concerns and the development stage of the service, the following can still bypass the security feature: VPN and SASE/SSE tunnels, Hyper-V VMs, including WSL, stack bypass technologies and deactivation of said feature by local administrators.
Microsoft noted that it will announce when Insiders can start testing ZTDNS once the private preview has concluded.
