Rapid advances in information and communication technology have opened the way to a huge amount of information for operational exploitation. But it is well known that an increase in available data does not imply a consistent increase of useful information needed for decisions. The transformation of collected data into knowledge is a complex process strongly dependent on the capability of analysis and the availability of technological tools. As the events of September 11 clearly demonstrated, the lack of ability for processing data into useful information severely limits the intelligence outputs and the knowledge needed for operational capability and responsiveness. Taking advantage of experience in business intelligence techniques developed for business purposes, the management of strategic information and the intelligence support to operations can be strongly improved. In this analysis requirements and constraints for collecting, archiving and processing data are identified. These in particular are stressed, as the accuracy of data is a key factor to a positive increase of information value at different stages of the process and finally to knowledge. Accuracy requirements are the first bridge to the missing link between intelligence and security tools. Security can provide integrity of data and minimize the injection of disinformation into the process and the poisoning of query results. Synergically, intelligence technology can strengthen the bridge to security providing tools for a proactive management of security services and an improved resilience to attacks.
