Abstract: A system tracks ownership data for data resources coupled on a network. The system includes a data extractor for extracting data resource communication activity data from a plurality of network activity data sources, a database of organizational data resource ownership data, and a communication activity report generator for correlating extracted data resource communication activity data and organizational data resource ownership data so that ownership of communication activity may be tracked. The data extractor obtains network activity data from a variety of data sources such as firewalls, routers, servers, PBXs, softswitches, media gateways, SS7 signaling points, integrated access devices, and calling card imports. Network activity data about communication activity may be obtained directly from the data resources initiating the communication activity or from data sources that handle communication activity initiated by a data resource.

Abstract: A disclosed system comprises user sites with monitor devices that report uncategorized content sites requested by users to a master site via an external network such as “the Internet.” The master site administers categorization of content sites, which is carried out by an unknown site reviewer. The master site transmits the resulting site categorization data to the monitor devices. The monitor devices use this data for subsequent user requests to determine categories of content sites requested by users. The monitor device further determines whether users are authorized to access content sites according usage policies established for the users sites.
