Remote desktop / remote control desktop / remote desktop protocol means to take control of one computer from another one.

This can be very useful if say you need to work at home but access some services from your workplace or files off your work computer etc.  It’s also used extensively by IT support staff.

Within a company network it can be safe but if you open your firewall to allow remote access through the firewall then this can be a problem.

Microsoft’s implementation of remote access has vulnerabilities that the hackers know about and they scan IP addresses looking for anyone that has left that door in their firewall available (typically RDP is on TCP port 3389).

If you use remote access through your firewall – make sure you’re safe or turn it off permanently.
