| Definition |
A security system intended to protect an organization´s network against external threats, such as hackers, coming from another network, such as the Internet. A firewall prevents computers in the organization´s network from communicating directly with computers external to the network and vice versa. Instead, all communication is routed through a proxy server outside of the organization´s network, and the proxy server decides whether it is safe to let a particular message or file pass through to the organization´s network.

| Context |
Where personal data are incorporated into material held on an Internet site available for public access or for access by members of a closed user group, different considerations apply. Unless access is restricted to a closed user group and is coupled with encryption and/or a firewall, any person with access to the Internet can visit the site and extract information held on it.
