Threats posed by cyber attacks have been increasing year by year, and such security risks, for most entities whether corporate, government or individuals, cannot be dismissed. There is ongoing effort on human resources development for cyber security measures by the governments and academia, however, it would be far optimistic to assume that the current human resources are sufficient to deal with ever-evolving cyber attack techniques. As such, security operations which is feasible with limited manpower are desired. This paper will introduce research for efficient and effective security operations based on new technologies.
