VPN

VPN (stands for Virtual Private Network) is a technology that is commonly used to connect remote workers and telecommuters to main office's local area network, securely.

Using a VPN connection between remote workstation and an office network will create a secure connection between the two and typically the telecommuter using VPN client can see the office network exactly as he/she could see the network when being connected locally to the network (i.e. all shared drives, servers, printers, etc are visible).
