Why is there so much outgoing traffic shown on port 443
Looking at our firewatch, I see a lot of computers in our building that have a lot of outgoing traffic through port 443 to lots of different IP addresses. How can i prevent that? I can't just block 443 as we also have a mail and web server controlling our email and website.
I am testing one computer that i just turned on and opened no applications and still shows a lot of outgoing traffic.
Anyone have thoughts to this?
