The group for analysis of information warfare (the IW group) started within the FoRMA project early in 2000. The group was formed to identify threats and opportunities in the IW field. The purpose of this report is to present a summary of the work accomplished and the conclusions that the IW group arrived at mainly through war gaming. The report contains a discussion of terms within the IW field, conclusions from several war games and a number of concepts that have been produced in close connection with the war gaming process. For anyone wanting to read more, there are references to other documents published by the IW group. Another purpose of this summarizing report is to spread of the IW group and to contribute to the discussion about the role of IW in the future.
