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.

The purpose of this study is to suggest the educational system and direction of cyber operations officers of non-cyber operations forces who do not specialize in cyber operations. In order to carry out cyber operations as a joint operation, non-Cyber Operations officers must also know about cyber operations, but there is no education system for them at present, Since there is almost no previous research on this, research in the relevant field is necessary. Therefore, the education system was developed based on the prior literature review, that is, the education system, that is, the necessity of education, the object of education, the goals and contents of the education, and the curriculum. In addition, the relevant experts confirmed the validity of each item with Delphi method, and as a result, some improvement was needed, but it was shown to be suitable as a whole. In addition, detailed educational program development can be developed based on this in the future.

As technology evolves, Internet usage continues to grow, resulting in a geometric increase in network traffic and communication volumes. The network path selection process, which is one of the core elements of the Internet, is becoming more complex and advanced as a result, and it is important to effectively manage and analyze it, and there is a need for a representation and visualization method that can be intuitively understood. To this end, this study designs a framework that analyzes network data using BGP, a network path selection method, and applies it to the cyber common operating picture for situational awareness. After that, we analyze the visualization elements required to visualize the information and conduct an experiment to implement a simple visualization. Based on the data collected and preprocessed in the experiment, the visualization screens implemented help commanders or security personnel to effectively understand the network situation and take command and control.
