Such solutions have been studied in-depth by
concepts like the NATO Network-Enabled Capabilities
(NNEC) [2]. NNEC doctrine [3] has identified four essential
components that must be addressed to enable generic solutions
for secure and efficient information sharing: (1) the networks
and systems supporting the command and control information
flows; (2) the information itself; (3) the processes and
procedures that ensure availability of information when and
where needed, and; (4) the policies and doctrine that permit
and facilitate the information exchange to happen. It is well
understood that no solution will satisfy the requirements for
efficiently federating information unless it properly addresses
all of the four above mentioned components.
