Process control systems used in most domestic petrochemical corporates today are based on the Windows platforms. As technology leans toward opened environment, the exposure risk of control systems is increasing. However, not many companies are preparing for various cyberattacks due to lack of awareness and misunderstanding of cyber intrusion. This study investigated the extent of how much exposed the petrochemical process control system is to security threats and suggested practical measures to reduce OT cybersecurity vulnerabilities. To identify the cyber threat status of process control systems, vulnerabilities of the Windows platform, a principal cyber threat factor, have been analyzed. For research, three major DCS providers in Korea and the discontinuation of Windows platform of 635 control systems were investigated. It was confirmed that 78% of the survey subjects were still operating in the discontinued windows platforms, and those process control systems were operated in a state vulnerable to cyber intrusions. In order to actively cope with these cyber threats, legal regulations such as designation of critical infrastructure for major petrochemical facilities which is implemented in advanced countries such as the United States are needed. Additionally, it is necessary to take the initiative in eradicating security threats to the process control systems by aggressively introducing security solutions provided from existing DCS suppliers. This paper was submitted to Professor Ko JaeWook's retirement anniversary issue.

In Korea, national information infrastructure has been grown well because of the rapid growth and supply of Internet, but threats of cyber terror and cyber war are also increasing. Cyber attacks on knowledge information society threaten industry, economy and security. Major countries realize that cyber attacks can cause national heavy loss. So, they are trying to adopt policy on their cyber safe. And natural environmental crisises are increasing around the world. Countries such as India and Philippine in which tsunami, typhoon and earthquake are often occurring have national systematic disaster management system that can prevent and recover. We need systematic management for prevention and recovery from cyber terror, and need to establish national cyber disaster management system. Therefore, in this paper, we analyze major countries's cyber security policy and suggest a method of establishing the national cyber disaster management system.

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 Army TIGER System, which is being deployed to implement a future combat system, is expected to bring innovative changes to the army's combat methods and comabt execution capability such as mobility, networking and intelligence. To this end, the Army will introduce various systems using drones, robots, unmanned vehicles, AI(Artificial Intelligence), etc. and utilize them in combat. The use of various unmanned vehicles and AI is expected to result in the introduction of equipment with new technologies into the army and an increase in various types of transmitted information, i.e. data. However, currently in the military, there is an acceleration in research and combat experimentations on warfigthing options using Army TIGER forces system for specific functions. On the other hand, the current reality is that research on cyber threats measures targeting information systems related to the increasing number of unmanned systems, data production, and transmission from unmanned systems, as well as the establishment of cloud centers and AI command and control center driven by the new force systems, is not being pursued. Accordingly this paper analyzes the structure and characteristics of the Army TIGER force integration system and makes suggestions for necessity of building, available cyber defense solutions and Army TIGER integrated cyber protections system that can respond to cyber threats in the future.

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.

North Korea's cyber warfare capability is becoming a serious security threat to Korea because most of the operational systems of social infrastructure and advanced weapons system are all networked. Therefore, the purpose of this article is to examine what the Korean government should do to strengthen cyber security capabilities toward North Korea. For this purpose, this article analyzed North Korea's cyber attack cases against Korea by categorizing according to threat type and purpose. The research findings are as follows. It is necessary first, to have aggressive cyber protection and attack capabilities; second, to establish an integrated cyber security control tower that can be overseen by the national government; third, to need to legislate domestic cyber- related laws; fourth, to build a multilateral & regional cyber cooperation system. The implication of these findings are that it needs to be strengthened the cyber security capability from the cyber threats of North Korea by minimizing the damage during the peacetime period and for the complete warfare in case of emergency.

Nuclear power plant data networks and their associated safety systems are being modernized to include many information technology (IT) networks and applications. Along with the advancement of plant data networks (PDN), instrumentation and control systems are being upgraded with modern digital, microprocessor-based systems. However, nuclear PDN is confronted significant side-effects, which PDN is exposed to prevalent cyber threats typically found in IT environments. Therefore, cyber security vulnerabilities and possibilities of cyber incidents are dramatically increased in nuclear PDN. Consequently, it should be designed fully ensuring the PDN meet all reliability, performance and security requirements in order to overcome the disadvantages raised from adaption of IT technology. In this paper, we provide technical security criteria should be used in design and evaluation of secure PDN. It is believed PDN, which is designed and operated along with these technical security critera, effectively protect against possible outside cyber threats.

Considerable number of major countries have put great efforts to leverage the efficiency of power consumption using Smart Grid in order to resolve the critical issues with drastical growing demands regarding electricity, the crisis of environmental pollution and so on. There has been increasing number of researches to construct Smart Grid in Korea as well. The threats of cyber terror attacks which might cause national crisises in terms of economy and society have been climbing up because of the fact that Smart Grid employs bi-directional communications embedding the cyber threats from existing/legacy communication networks. Consequently, it is required to build concrete response processes including investigation and analysis on cyber breaches into Smart Grid. However, the digital evidence acquisition techniques do not suffice to be deployed in Smart Grid systems despite of the fact that the techniques, against cyber breaches into well-known networks, have been studied in plenty of time. This work proposes a novel digital evidence acquisition scheme appropriate to Smart Grid systems through intensive investigation of the evidence acquisition requirements in Smart Grid and the historical evidence acquisition methods.
