Defender pre-reqs - ports.
Hi We are running through the pre-reqs and unsure what exactly is required for the firewall section and allowing the ports: https://learn.microsoft.com/en-us/defender-for-identity/prerequisites#p...

It should be read like "The machine running the sensor should be allowed to connect to the MDI azure backend via port 433 using TCP."
Or "The machine running the sensor should be allowed to connect to all your DNS servers via port 53 using TCP or UDP".
Does this clarify the table syntax?

We haven't made any changes to our firewall, so I presume most of the traffic passes over port 443? Either way our DCs with agents are working.
