Controlling the Language of Security

A security policy specification that guarantees the reliability and availability of home networks has been developed by computer scientists at Kyungpook National University and the Electronics and Telecommunications Research Institute in South Korea. "Whenever a new access to the home network is found, it should be able to authenticate and authorize it and enforce the security policy based on rules set by the home administrator," the researchers say.

The researchers developed the Home security Description Language (xHDL), which includes the necessary notation for consistently describing and specifying the security policy, and ultimately securing a home network. XHDL consists of a combining-rule element, authentication element, user element, object element, object-group element, role element, and rule elements. Each term could be used to run a browser-based control center. The domestic administrator would have simple control options for allowing access to the home network for specific devices and for controlling the packets of information that pass through the gateway to and from the Internet. XHDL would protect home networks from cyberattacks and ensure that it is available for use.
