Remote desktop is technology that streams a computer's screen to another device and sends your keyboard and mouse input back, so you can operate a distant machine. Examples include Microsoft RDP, VNC, Chrome Remote Desktop, TeamViewer and AnyDesk.
Why it matters
IT teams use it to support users and manage servers, and individuals use it to reach a work or home computer from elsewhere. Because it grants full control, it is a frequent attack target: exposed RDP ports on port 3389 are heavily scanned and attacked by brute-force and ransomware operators. Strong passwords, multi-factor authentication and a VPN make it much safer.
Example
On Windows, the built-in client is run with:
mstsc /v:192.168.1.50The target must have Remote Desktop enabled and a user permitted to connect. Instead of exposing port 3389 to the internet, connect through a VPN or a gateway that enforces authentication.
Common mistakes
- Forwarding port 3389 straight to the internet.
- Using weak or reused passwords, with no multi-factor authentication.
- Leaving remote access tools running after a support session ends, or installing them at a stranger's request, a common scam.
