Earlier this week, the company released its own Linux version in its format Azure Sphere OS. And before that, it became known that more Linux distributions will now be available through the Microsoft Store.
The latest news is that the company has decided to transfer its benefits Windows Defender Firewall in the Linux subsystem (WSL). In other words, WSL is now supported by the Windows Defender firewall. The company made this announcement along with the release of Windows 10 Insider Preview Building 17650 on the Skip Ahead Ring.
As a result of this change, Windows 10 users can now add specific WSL-specific rules to the Defender firewall. The whole process is similar to adding rules for any common Windows process.
This change will also allow someone to take advantage of WSL firewall notifications. So when a Linux tool tries to allow access to a port via SSH or web server, the Defender Firewall will let you know to give it access.
