Windows Defender Firewall with Advanced Security – what is that Advanced Security part? Let’s remove the dust … (Part 4 – Allow the connection if it is secure rules and Connection security rules (IPSec) and limit to certain application)

In this last post regarding security that you can apply by using Windows Defender Firewall with Advanced Security I would like to point out another option that is available when you start to configure more complex scenarios by using Connection security rules.

In this example I will force user (in this case Bill) that needs to connect from a specific workstation (PAW) (in this case C2) to use specific application (in this case Firefox) to access the web site on server (in our case SRV2). You will see that connection will not be established if Bill uses Edge (or some other browser).

This example can be an starting point to not only allow the connection to some servers services by using combination of correct user from correct workstation but also application that should be used for such connection.
