  • During the recent years, cyber attacks have been increasing both in the private sector and the government. Those include the DDOS cases in 2009, the Blue House cyber attack, bank hackings etc. Cyber threats are becoming increasingly serious. However, there is no basic law related to cyber security at present, and regulations related to cyber security are scattered in various domestic laws. This can lead to confusion in the application of the law and difficult to grasp the regulations related to cyber security. In order to overcome this situation, the bill on the prevention and countermeasures against cyber crisis was initiated in 2006, but it has been abrogated. Since then, it has been repeatedly proposed, but it has been abrogated repeatedly due to the overlapping of existing laws and concerns about infringement of personal information. The most recent initiative was the National Cyber Security Act, which was initiated by the government in January 2017. The act focuses on resolving the absence of a basic law related to cyber security, strengthening its responsiveness in the event of a cyber security crisis, and fostering security strength. Therefore, this study seeks to contribute to the establishment of National Cyber Security legislation as a basic law of cyber security by examining the necessity of National Cyber Security legislation through comparative legal analysis with existing domestic laws related to cyber security and suggesting policy implications.

  • In this paper, we introduce a smart city-cyber-security-grid-matrix methodology, as a result of research on overall cyber security of smart cities. The identified cyber security risks that threaten smart cities and smart-city-cyber-security-threat list are presented. The smart-city-cyber-security-requirements necessary to secure the smart city cyber security with the developed smart city-cyber-security-grid-matrix are given in this paper. We show how the developed smart city-cyber-security-grid-matrix methodology can be applied to real world. For it, we interlocked the developed smart city-cyber-security-grid-matrix methodology with the cyber-security-framework of the National Institute of Standards and Technology, and developed a framework-based smart city-cyber-security-grid-matrix. Using it, it is easy and comfortable to check the level of cyber security of the target smart ciy at a glace, and the construction and operation of the smart city security system is systematized.

  • The purpose of this study is to investigate the direct effect of victimization experience on cyber security behavior and the indirect effect of information protection awareness through the Dual Process Theory. Baron & Kenny regression analysis was conducted and the results are as follows - first, victimization experience has a positive effect on cyber security behavior; second, the relationship between victimization experience and cyber security behavior is mediated by cyber security awareness; and third, the direct effect of victimization experience on cyber security behavior and the indirect mediating effect of cyber security awareness are both positive (+). The direct effect of victimization experience on cyber security behavior is analyzed to be relatively large compared to the indirect effect that cyber security awareness has on cyber security behavior. Based on these results, It is suggested that periodic cyber security education and campaign policies are needed to enhance cyber security behavior.

  • Nuclear Power Plants (NPPs) are the most protected facilities among all critical infrastructures (CIs). In addition to physical security, cyber security becomes a significant concern for NPPs since swift digitalization and overreliance on computer-based systems in the facility operations transformed NPPs into targets for cyber/physical attacks. Despite technical competencies, humans are still the central component of a resilient NPP to develop an effective nuclear security culture. Turkey is one of the newcomers in the nuclear energy industry, and Turkish Akkuyu NPP has a unique model owned by an international consortium. Since Turkey has limited experience in nuclear energy industry, specific multinational and multicultural characteristics of Turkish Akkuyu NPP also requires further research in terms of the Facility's prospective nuclear security. Yet, the link between "national cultures" and "nuclear security" is underestimated in nuclear security studies. By relying on Hofstede's national culture framework, our research aims to address this gap and explore possible implications of cross-national cultural differences on nuclear security. To cope with security challenges in the age of hybrid threats, we propose a security management model which addresses the need for cyber-physical security integration to cultivate a robust nuclear security culture in a multicultural working environment.

  • Recently, cyber attacks against public communications networks are getting more complicated and varied. Moreover, in some cases, one country could make systematic attacks at a national level against another country to steal its confidential information and intellectual property. Therefore, the issue of cyber attacks is now regarded as a new major threat to national security. The conventional way of operating individual information security systems such as IDS and IPS may not be sufficient to cope with those attacks committed by highly-motivated attackers with significant resources. As a result, the monitoring and control of cyber security, which enables attack detection, analysis and response on a real-time basis has become of paramount importance. This paper discusses how to improve efficiency and effectiveness of national cyber security monitoring and control services. It first reviews major threats to the public communications network and how the responses to these threats are made and then it proposes a new approach to improve the national cyber security monitoring and control services.

  • As core technologies(IoT, 5G, Cloud, Bigdata, AI etc) leading the Fourth Industrial Revolution promote smart convergence across the national socio-economic infrastructure, the threat of new forms of cyber attacks is increasing and the possibility of massive damage is also increasing. Reflecting this trend, cyber security is expanding from simple information protection to CPS(Cyber Physical System) protection that combines safety and security that implements hyper-connectivity and ultra-reliability. This study introduces the recent evolution of cyber attacks and looks at the next generation cyber security technologies based on the conceptual changes of cyber security technologies such as SOAR(Security Orchestration, Automation and Response) and Zero Trust.

  • Since the global spread of COVID-19, social distancing and untact service implementation have spread rapidly. With the transition to a non-face-to-face environment such as telework and remote classes, cyber security threats have increased, and a lot of cyber compromises have also occurred. In this study, cyber-attacks and response cases related to COVID-19 are summarized in four aspects: cyber fraud, cyber-attacks on companies related to COVID-19 and healthcare sector, cyber-attacks on untact services such as telework, and preparation of untact services security for post-covid 19. After the outbreak of the COVID-19 pandemic, related events such as vaccination information and payment of national disaster aid continued to be used as bait for smishing and phishing. In the aspect of cyber-attacks on companies related to COVID-19 and healthcare sector, we can see that the damage was rapidly increasing as state-supported hackers attack those companies to obtain research results related to the COVID-19, and hackers chose medical institutions as targets with an efficient ransomware attack approach by changing 'spray and pray' strategy to 'big-game hunting'. Companies using untact services such as telework are experiencing cyber breaches due to insufficient security settings, non-installation of security patches, and vulnerabilities in systems constituting untact services such as VPN. In response to these cyber incidents, as a case of cyber fraud countermeasures, security notices to preventing cyber fraud damage to the public was announced, and security guidelines and ransomware countermeasures were provided to organizations related to COVID-19 and medical institutions. In addition, for companies that use and provide untact services, security vulnerability finding and system development environment security inspection service were provided by Government funding programs. We also looked at the differences in the role of the government and the target of security notices between domestic and overseas response cases. Lastly, considering the development of untact services by industry in preparation for post-COVID-19, supply chain security, cloud security, development security, and IoT security were suggested as common security reinforcement measures.

  • Despite much discussions on cyber-terrorism in South Korea, several missing issues could be addressed. This paper attempts to deal with such missing but important issues. In South Korea, there has been little attentions on cyber-terrorism with the respects of national security strategy development under macro framework responding to future security environment. This article focuses on such issues. In other words, the purpose of this paper evaluates the meaning of national security threats raised from cyber-terrorism as a mode of security threats and proposes the matter of cyber-terrorism within the development of national security strategy in the future security environment. several issues in this discussion pass some important messages for the construction of national security strategic approach framework within the future security environment adding cyber-space. in the future environment, a new space called cyber is added as an important external condition which might determine the security of individuals, societies, and nations. Therefore, the fundamental strategic framework should be prepared. After that, the trend and direction of future technological advancement should be understood and the identity, nature, and types of threat should be analyzed. Also, after that, various responses and countermeasures are together constituted in the aspect of function and system regarding various anticipated threats of the future human society including cyber-terrorism.
