The technology used for remote server access includes protocols and tools such as VPN (Virtual Private Network), SSH (Secure Shell), and remote desktop applications. VPNs create secure tunnels over the Internet, enabling users to securely connect to remote networks. SSH provides a secure way to access a server's command line interface, allowing for safe management of resources remotely. Remote desktop applications facilitate full access to a computer’s graphical interface, enabling users to operate software or files just as if they were at the server's physical location.
