How to protect a computer on a local network?

Question

firewall

There is a computer on the local network at work. I want no one to be able to scan it and check what programs are installed there.
I have radmin installed on it and I also use rdp.
What should be installed from the software and how to configure Windows?

Answer 1

Contact your system administrator.

Answer 2

And then you will be asked for what purpose there was a connection to these addresses for such and such a duration.
Do not create problems for yourself or your superiors.
PS RDP is built into the OS, Teamviewer can run without installation
