Cyber-attacks occur in the blink of an eye in cyberspace, and the damage is increasing all over the world. Therefore, it is necessary to develop a cyber common operational picture that can grasp the various assets belonging to the 3rd layer of cyberspace from various perspectives. By applying the method for grasping battlefield information used by the military, it is possible to achieve optimal cyberspace situational awareness. Therefore, in this study, the visualization screens necessary for the cyber common operational picture are identified and the criteria (response speed, user interface, object symbol, object size) are investigated. After that, the framework is designed by applying the identified and investigated items, and the visualization screens are implemented accordingly. Finally, among the criteria investigated by the visualization screen, an experiment is conducted on the response speed that cannot be recognized by a photograph. As a result, all the implemented visualization screens met the standard for response speed. Such research helps commanders and security officers to build a cyber common operational picture to prepare for cyber-attacks.

In the case of unauthorized individuals, systems and entities or process threatening the instrumentation and control systems of nuclear facilities using the intrinsic vulnerabilities of digital based technologies, those systems may lose their own required functions. The loss of required functions of the critical systems of nuclear facilities may seriously affect the safety of nuclear facilities. Consequently, digital instrumentation and control systems, which perform functions important to safety, should be designed and operated to respond to cyber threats capitalizing on the vulnerabilities of digital based technologies. To make it possible, the developers and licensees of nuclear facilities should perform appropriate cyber security program throughout the whole life cycle of digital instrumentation and control systems. Under the goal of securing the safety of nuclear facilities, this paper presents the KINS' regulatory position on cyber security program to remove the cyber threats that exploit the vulnerabilities of digital instrumentation and control systems and to mitigate the effect of such threats. Presented regulatory position includes establishing the cyber security policy and plan, analyzing and classifying the cyber threats and cyber security assessment of digital instrumentation and control systems.

The interest in cyber counseling services has been increased recently by needs and merits of cyber counseling service found through various related studies. A cyber counseling service system has not only merits but also demerits such as anonymous one-off access and difficulties of forming relations. In this study, a cyber counseling service system using class homepage was developed and implemented in order to investigate counseling methods that can enhance merits and supplement demerits of cyber counseling services. As a result, it was found that the implementation of a cyber counseling service system using class homepage can fill counseling needs of students, teachers and parents by providing various counseling methods and inducing active interaction using the site-on function. Interesting menu on class homepage was effective to lead students and parents to visit the cyber counseling room, and they prefered the secret board and counseling cases to e-mail counseling. Prior acquisition of information about students and the environment allowing teachers to continuously observe students improved counseling effects and solved problems of existing counseling services.

Cyberspace is closely related with one another, transcending the spacetime throughout the world, and is already located in the most important area of our lives. However, if the organizational cyber terror happens like the national paralysis crisis of major information network such as the previous 1.25 the Internet crisis, the possibility of cyber crisis highly damaging our whole society such as the leakage of the national secrecy and advanced technology is increasing. But we haven't set up the institutional procedure systematically performing the national cyber security management affairs yet. So, in case of cyber crisis, this is highly likely to damage the aspects of national and personal level. On this point, this study looks into the examples of legislation related to our cyber security, and suggests the implication on the revision direction of national cyber security management regulations through relative examination about the examples of legislation in major countries.
