*ORA-LITE:

Overview | Sponsors | Hardware Requirements | Software | Training & Sample Data

*ORA-LITE is a dynamic meta-network assessment and analysis tool developed by CASOS at Carnegie Mellon.  It contains hundreds of social network, dynamic network metrics, trail metrics, procedures for grouping nodes, identifying local patterns, comparing and contrasting networks, groups, and individuals from a dynamic meta-network perspective. *ORA-LITE has been used to examine how networks change through space and time,  contains procedures for moving back and forth between trail data (e.g. who was where when) and network data (who is connected to whom,  who is connected to where …),  and has a variety of geo-spatial network metrics, and change detection techniques.  *ORA-LITE can handle multi-mode, multi-plex, multi-level networks.  It can identify key players, groups and vulnerabilities, model network changes over time, and perform COA analysis.  Although all metrics available in *ORA-LITE have been tested with large networks (10^6 nodes per 5 entity classes); *ORA-LITE is itself limited to a maximum of 2,000 nodes per entity class. So you can have 2000 agents, 2000 organizations, and so on. The Professional version of ORA which is available from Netanomics (www.netanomics.com) has no limit on the number of nodes. Distance based, algorithmic, and statistical procedures for comparing and contrasting networks are part of this toolkit.

Based on network theory, social psychology, operations research, and management theory a series of measures of “criticality” have been developed at CMU.  Just as critical path algorithms can be used to locate those tasks that are critical from a project management perspective, the *ORA-LITE algorithms can find those people, types of skills or knowledge and tasks that are critical from a performance and information security perspective.  Each of the measures we have developed are calculated by *ORA-LITE on the basis of network data like that in the following table.

*ORA-LITE can be applied both within a traditional organization or on covert networks.

For information on ORA-PRO
ORA-PRO is offered by Netanomics, visit their website for additional software information. ORA-PRO supports unlimited number of nodes, geo-spatial and temporal analytics and visualization. In addition, in ORA-PRO specialized sub-tools for twitter and blog importing, geo-spatial network metrics. Data pruning techniques for big data are also available. ORA-PRO is available both for Mac and PC.
