Remote access is access to organizational information systems by users (or processes acting on behalf of users) communicating through external networks (e.g., the Internet). Remote access methods include, dial-up, broadband, and wireless. Virtual private networks (VPNs), when adequately provisioned with appropriate security controls, are considered internal networks, rather than a remote access method. Enabling access to the network from outside introduces security risks which must be addressed through implementation of strict controls and procedures, such as authentication and defining what resources can be accessed.
