Cyberspace Situation representation based on Niche theory

The rapid development of Internet leads to an increase in system complexity. Traditional network management can not meet the requirement, and it should evolve to fusion based cyberspace situational awareness (CSA). Knowledge representation as the basis of situation awareness uses a uniform standard method to gather massive network management information and express various content such as network operation, user interaction, cyberspace situation factors, and so on, and therefore it plays a vital role to simplify situational awareness and integrate unit network management. Borrowing a good idea from niche theory, we establish a multi-view hypervolume cyberspace situation niche, which can provide an accurate comprehensive detailed description of cyberspace situation using three views and a number of metrics. Then we take situation assessment, network analysis and visualization as examples to illustrate the applications and advantages of situation niche.
