I am going back and forth on this one with a consultant on this one and need an expert opinion. So, I turn to you :) When configuring webemail (such as owa) that is using https, is it better to change the default port (443) to an uncommon port (20000)for security reasons? Does it secure it further by doing this?
that would be security thru obscurity, will add one more layer of secure but it would be very easy to break this one doing someing as nmap scan would reveal this
Wouldn't it cause more issues than anything if you try to access that site from inside an org that only allows port 80/443 and 21 out?
none that i would think of.
Thank you in advance for any opinions you may share.
