A Threat Targets Ranking Method Based on Competition

We proposed a threat targets ranking method based on competition. Using a competitive function, we set up several competitive mechanisms. By using these competitive mechanisms, we successfully give an objective threat targets ranking, and we effectively avoid the normalization problem of threat attributes. This method makes good use of the joint information of targets, which can improve the use of mutual information to give a more reasonable result. We give an example to verify the effectiveness of the method.
