Is it possible to conduct a "secure session" remotely on someone else's computer?

Question

Remote access

Is it possible to conduct a remote session on another computer in this way:
1. A specialist could remotely, for example, demonstrate software, but
2. So that the computer owner would not be able to interrupt remote access and keep all the software at home
3. If such a solution exists, is there an analogue for the Mac operating system?

Answer 1

Turn inside out.
Give him remote access to your computer and demonstrate the software installed on your computer.
Another option is to demonstrate according to the precepts of Kin-Dza-Dza:

- Can I have a look?
- Look.
“Actually, I'm not a gravitsappa expert. Let's go show my chatlanin, he'll check.
- Now, let's put the pin.

those. show a non-full-functional version; until you put the "tap" - it will not fly.

Answer 2

It is necessary to do the opposite
TimWeaver or AnyDesk in the "view only" mode .... it is also a presentation mode. It will be enough.
By the way, it was well suggested here too - Zoom

Answer 3

No. The owner of the computer can always terminate the connection forcibly by turning off the computer.
Why not do the opposite: run a demo on a remote computer, and give the person who should be watching only access to view this demo?
There is a zoom, for example.

Answer 4

The owner of the computer always has the opportunity to interrupt the session by stupidly pulling the plug out of the socket :) Demonstration should be carried out only at home, providing him with remote access.

Answer 5

Depending on the type of remote connection (rdp/vnc/anydesk/teamviewer), the ability to harm the connected user is different.
The most primitive protocol is vnc, in its original form it is only transferring the contents of the screen, keyboard and mouse (even there is no sound), but even in this case, you can quietly press win + r combinations very quickly, type a command and press enter, with proper motivation this is automated and works at maximum speed, in some cases it will be almost impossible to notice with your eyes.
What can we say about anydesk/teamviewer combines? there, a person who connects can copy files in the background, connect to a local network and mess even more (rdp gives network access to the server machine and, by the way, vice versa - to a connected client, so a connected client may also be under attack)
You can set up a very limited user (by the way, there is such a guest account) who has a minimum of capabilities, but control is still not complete, and most importantly, it is difficult to understand what an attacker could do so bad.
Be careful, an attacker can take advantage of access to your Internet (and local network), there are few scripts to do nasty things, but they exist. This means that he can launch an application, open a browser, and so on.
Virtualization will provide absolute protection - you set up a clean OS in a virtual machine and give remote access to it, at the end of work you delete the machine (you can take a snapshot and delete it, and leave the configured OS for another time). You can even personally disable the network for this virtual machine in principle.
