This question seems silly. We are in the modern internet, yet I got curious after doing several scans of my outside network. Running Zenmap, it listed ports 22 & 443 as open. I then tried using a service “Shields up” listed on the GRC website. It also found them open. Curiously, UpNP is not showing up as active or in use. It was on my MacBook Air m1. I was able to close it by disabling “Airplay”. But with the iPad, this is head scratcher. Why would it be open? Is it not supposed to be closed except for accessing a secure server, like software update?
