<p>A remotely configurable transmission security filtering, monitoring and alarm unit (108) is installed locally between an end-user's workstation (102) or network (100) and a wide-area, non-secure network (106) like the Internet. A management unit (104) for configuring and monitoring one or more of the remotely configurable security units (108) connects to the wide-area network (106) and transfers alarm criteria and other configuration data particular to each security unit (108). The local security units (108) filter digital transmissions between their workstations (102) or network (100) and the wide-area network (106) such as the Internet, according to the alarm criteria. The management unit (110) may upload encryption parameters to the remote local security units (108). In response to new security information, such as newly discovered security threats, the management unit (104) reconfigures the alarm criteria at the local security units at their respective locations around the Internet or other wide-area network (106).</p> |
