Remote desktop-style access is interactive control of one computer from another over a network. It lets an operator move the mouse, type, open files, and run commands as if sitting at the remote device. In legitimate use, this supports help-desk work, administration, and troubleshooting.
In cyber security, the risk is that the same capability can be used by attackers after a user installs a trusted remote support tool or approves a session under false pretenses. Because the activity can look like normal IT support, it may blend into routine operations and avoid suspicion. Defenders should verify every remote access request, restrict who can start sessions, log and alert on unusual support tools, and treat unexpected interactive control as a potential intrusion rather than routine maintenance.
