I have a 4 PC wired network with wireless internet access. One of the PCs is for my kids. How can I restrict their access to just the internet and the files on their machine, but allow me access to everything? Windows XP home.
What is a VPN?
VPN is (Virtual Private Network) were first used by companies to enable their employees to securely access internal systems such as email remotely (e.g. from home or while on business trips). Today they are increasingly being used for personal use by individuals to protect their privacy while online in public places (e.g. when using the wi-fi connection in a cafe) or in a country where the internet is censored / blocked (e.g. China, Saudi Arabia).
