Alvin,
I am my ISP and IT support person. My Fedora laptop cannot be
remotely administered. I am inconvenienced by this. If I want to do
something with it, I have to get up and walk to where I have it
stored. From the laptop, I can administer my desktop, because I have
ssh set up. My desktop stays behind my firewall. My laptop gets
exposed.
I have been on a commercial site where the Windows laptops were
administered remotely, from somewhere in the USA, I think. I don't
know how secure they were. The company did not have particularly nasty
security requirements, i.e. they were not managing people's personal
data, or military secrets.
