Recently, the United States has been trying to strengthen its cybersecurity by upgrading its position as an Unified Combatant Command that focuses on the Cyber Command in the United States, strengthening operations in cyberspace, and actively responding to cyber threats. Other major powers are also working to strengthen cyber capabilities, and they are working to strengthen their organization and power. The world demands economic power for its own interests rather than its own borders. But Cyber World is a world without borders and no defense. Therefore, a cyber weapon system is necessary for superiority in cyberspace (defense, attack) for national cybersecurity. In this paper, we analyze operational procedures for cyber weapons operation. And we design cyber weapons to analyze and develop the best cyber weapons to lead victory in cyberwarfare. It also conducts cyber weapons research to solve the confrontation between Cyber World.

The UAE government has set its sights on creating a smart, electronic-based government system that utilizes AI. The country's collaboration with India aims to bring substantial returns through AI innovation, with a target of over $20 billion in the coming years. To achieve this goal, the UAE launched its AI strategy in 2017, focused on improving performance in key sectors and becoming a leader in AI investment. To ensure public safety as the role of AI in government grows, the country is working on developing integrated cyber security solutions for SCADA systems. A questionnaire-based study was conducted, using the AI IQ Threat Scale to measure the variables in the research model. The sample consisted of 200 individuals from the UAE government, private sector, and academia, and data was collected through online surveys and analyzed using descriptive statistics and structural equation modeling. The results indicate that the AI IQ Threat Scale was effective in measuring the four main attacks and defense applications of AI. Additionally, the study reveals that AI governance and cyber defense have a positive impact on the resilience of AI systems. This study makes a valuable contribution to the UAE government's efforts to remain at the forefront of AI and technology exploitation. The results emphasize the need for appropriate evaluation models to ensure a resilient economy and improved public safety in the face of automation. The findings can inform future AI governance and cyber defense strategies for the UAE and other countries.

This study compares the influence of perceived public opinion on Internet users' willingness to expression in real space with in cyber space. In real space, people who perceive their opinions as minority opinion are reluctant to express theirs publicly because of fear of isolation. But cyber space is the anonymous world. So we can expect that people express their opinions freely without the fear of isolation in this space. This study's results provide the support for our expectation. In cyber space, the minority perception group has as the high willingness to expression of their opinion about the abrogation of the Korean Family Rights Raw as the majority perception group. Both of in cyber space and in real space, it is the perception failure group that makes discrepancy in the willingness to expression. This group has the lowest willingness to expression in both space. However, the other predictors of willingness to expression in cyber space are similar to those in real space. Issue salience, Communication apprehension, and Age are the very significant predictors of willingness to expression in both spaces. Sex and ideology are significant predictors in real space, while the frequency of online conversation is the significant predictor in cyber space.

In this day and age physical and cyber boundaries have converged due to the development of new technologies, such as the Internet of Things (IoT) and the Cyber Physical System (CPS). As the relationship between physical system and cyber technology strengthens, more diverse and complex forms of risk emerge. As a result, it is becoming difficult for single organization or government to fully handle this situation alone and cooperation based on information sharing and the strengthening of active defense systems are needed. Shifting to a system in which information suitable for various entities can be shared and automatically responded to is also necessary. Therefore, this study tries to find improvements for the current system of threat information collecting and sharing that can actively and practically maintain cyber defense posture, focusing particularly on the structuring of information sharing platforms. To achieve our objective, we use a risk communication theory from the safety field and propose a new platform by combining an action-oriented security process model.

As wireless communication functions begin to be installed in vehicles, cyberattacks that exploit vulnerabilities in wireless communication functions are increasing. To respond to this, UNECE enacted the UN R156 regulation to safely distribute the software installed in the vehicle by using the wireless communication function. The regulations specify the requirements necessary to safely distribute the software for vehicles, but only the abstract requirements are presented without information on the components and detailed functions necessary to develop and implement the requirements. Therefore, in this paper, we propose a security evaluation standard that can evaluate whether a safe SUMS is built using threat modeling, a method for systematically analyzing security threats.

This study is focused on forecasting the future of tole-democracy. Many Scholars expect that internet provides technological space needing realizing the tole-democracy or deliberate democracy. Especially in Korea, this expectation is higher than other nations because of political corruption and inefficiency. Therefore internet is intended to considering as new technologies reforming political process. In 16th the general election period, many candidates established home page and used as election campaign tool. And a little of home pages is payed attention to among voters. In spite of using internet as political medium, many political communication researchers have a doubt that internet will realize ideal direct democracy. It's reason is that internet is open and anonymous space. At anonymous space, communication participators is tended to be irresponsible and non-serious. Therefore it is hard that cyber-politics will be ideal type of democracy. In this context, this paper analyzed how pauicipators communicate with others at cyber bulletin board establishing candidate's home pages. Main research questions is how do discussions at cyberspace fulfill the conditions of deliberate democracy. Therefore, concrete questions include; who are participators at candidate's cyber bulletin board; which pattern do they communicate; what is the theme of communication; which effects do the anonymous character of cyberspace influence. To that purpose, this study conducted content analysis on 4,210 written matters at 82 cyber bulletin boards of candidate's home page establishing during 16th the general election period. It can be found that cyberspace in Korea still is not deliberate democracy space and not will be. Firstly, discussion patterns at cyber bulletin board is "candidate with supporters communication space. To be exact, it is said that candidate's home page is "the space of self-convincing among supporters." Secondly, the main themes of discussion are simple emotional expressions; "I support you!" "fighting" "Be vigor" etc. By contrast, real political contents'-central or local political matters - is relatively few. In the mode of expression, real political messages are more positive, logical than simple expressions, candidates private matters. Especially this characteristic will make cyberspace as "mutual slander space" consolidating anonymous characteristic of cyberspace. finally, Cyberspace in Korea still is not real "public sphere" realizing deliberate process. Therefore to be real public sphere, it is needed to participant's ethical maturity and political citizenship. In conclusion, it is difficult that cyberspace will reconstruct the Athene's Agora. On the contrary, Cyberagora will like to be irrespectable area fulfilling the sweeping. Making the deliberate space, technological possibility and ethical condition will have to be balanced together.

The development of modern ICT technology constitutes cyber world by using infrastructure in country and society. There is no border in cyber world. Countries around the world are carrying out cyber attacks for their own benefit. A cyber killer strategy is needed to defend cyber attacks. In order to defend the cyber attack or to determine the responsibility of attack, it is important to grasp the attacker origin point. Strategic cyber kill chains are needed to strike against the attacker origin. In this paper, we study the analysis of attacker origin. And analyze the cyber kill chain for attacker origin point strike. Study the efficient and customized cyber kill chain strategy for attacking the origin point. The cyber kill chain strategy will be a practical strategy to replace the power of nuclear and missiles with asymmetric power.
