It is no doubt that information technology is the key factor of national safety. Information technology is positively useful for national security such as crime prevention and detection, criminal investigation, disaster management, and national defense. However, it might be a threat to the security as we saw in the examples such as '3.4 DDoS attacks' and 'Nong-hyup Computer Network Failure.' Although the effect that information technology makes upon the national security is immense, the current legal system does not reflect these changes well. National security should be kept during 'prevention-response-recovery' process regardless it is in the online on offline. In addition, public administration for national security should be based on laws. However, the current legal system is lack of legislative basis on cyber and physical disaster, and the laws on the response to disaster might cause confusing. Therefore, this study examines the limitation of the current legal system on national security, and suggests directions for the development of the system based on the new establishment of the legal concept for 'national security'.

The information space, the main components of which are information resources, means of information interaction, and information infrastructure, is a sphere of modern social life in which information communications play a leading role. The objective process is the gradual but stable entry of the national information space into the European and world information sphere, in the context of which there is a legitimate question of its protection as one of the components of the national security of Ukraine. However, the implementation of this issue in practice immediately faces the need to respect the rights and fundamental freedoms guaranteed by international regulations and the Constitution of Ukraine, especially in the field of cybersecurity. The peculiarity of the modern economy is related to its informational nature, which affects the sharp increase in cyber incidents in the field of information security, which is widespread and threatening and affects a wide range of private, corporate, and public interests. The problem of forming an effective information security system is exacerbated by the spread of cybercrime as a leading threat to information security both in Ukraine and around the world. The purpose of this study is to analyze the state of cybersecurity and on this basis to identify new areas of the fight against cybercrime in Ukraine. Methods: the study is based on an extensive regulatory framework, which primarily consists of regulatory acts of Ukraine. The main methods were inductions and deductions, generalizations, statistical, comparative, and system-structural analysis, grouping, descriptive statistics, interstate comparisons, and graphical methods. Results. It is noted that a very important component of Ukraine's national security is the concept of "information terrorism", which includes cyberterrorism and media terrorism that will require its introduction into the law. An assessment of the state of cybersecurity in Ukraine is given. Based on the trend analysis, further growth of cybercrimes was predicted, and ABC analysis showed the existence of problems in the field of security of payment systems. Insufficient accounting of cybercrime and the absence in the current legislation of all relevant components of cybersecurity does not allow the definition of a holistic system of counteraction. Therefore, the proposed new legal norms in the field of information security take into account modern research in the field of promising areas of information technology development and the latest algorithms for creating media content.

A space system refers to a network of sensors, ground systems, and space-craft operating in space. The security of space systems relies on information systems and networks that support the design, launch, and operation of space missions. Characteristics of space operations, including command and control (C2) between space-craft (including satellites) and ground communication, also depend on wireless frequency and communication channels. Attackers can potentially engage in malicious activities such as destruction, disruption, and degradation of systems, networks, communication channels, and space operations. These malicious cyber activities include sensor spoofing, system damage, denial of service attacks, jamming of unauthorized commands, and injection of malicious code. Such activities ultimately lead to a decrease in the lifespan and functionality of space systems, and may result in damage to space-craft and, lead to loss of control. The Cybersecurity Adversarial Tactics, Techniques, and Common Knowledge (ATT&CK) matrix, proposed by Massachusetts Institute of Technology Research and Engineering (MITRE), consists of the following stages: Reconnaissance, Resource Development, Initial Access, Execution, Persistence, Privilege Escalation, Defense Evasion, Credential Access, Discovery, Lateral Movement, Collection, Command & Control, Exfiltration, and Impact. This paper identifies cybersecurity activities in space systems and satellite navigation systems through the National Institute of Standards and Technology (NIST)'s standard documents, former U.S. President Trump's executive orders, and presents risk management activities. This paper also explores cybersecurity's tactics attack techniques within the context of space systems (space-craft) by referencing the Sparta ATT&CK Matrix. In this paper, security threats in space systems analyzed, focusing on the cybersecurity attack tactics, techniques, and countermeasures of space-craft presented by Space Attack Research and Tactic Analysis (SPARTA). Through this study, cybersecurity attack tactics, techniques, and countermeasures existing in space-craft are identified, and an understanding of the direction of application in the design and implementation of safe small satellites is provided.

The forms of current war are diversified over the pan-national industry. Among these, one kind of threats which has permeated the cyber space based on the advanced information technology causes a new type of war. C4ISR, the military IT revolution, as a integrated technology innovation of Command, Control, Communications, Computer, Intelligence, Surveillance and Reconnaissance suggests that the aspect of the future war hereafter is changing much. In this paper, we design the virtual decoy system and intrusion trace marking mechanism which can capture various attempts and evidence of intrusion by hackers in cyber space, trace the penetration path and protect a system. By the suggested technique, we can identify and traceback the traces of intrusion in cyber space, or take a legal action with the seized evidence.

미국의 현행 원격탐사에 관한 법은 1992년에 제정되어 현재의 기술수준에 맞지 않는다는 비판을 받아 왔다. 이에 트럼프 대통령은 원격탐사분야를 포함해 상업적 우주활동에 대한 규제체제를 개혁함으로써 미국의 경쟁력을 제고하기 위해 2018년 5월 24일 Space Policy Directive (SPD) - 2를 발표하였다. 미 행정부의 규제개혁 노력은 국가안보와 경제적 번영을 동시에 추구하고자 하는 2017년 12월 17일 국가안보전략(National Security Strategy)의 틀에서 추진된다. 미 의회 또한 행정부의 규제개혁 노력에 발 맞춰 입법논의를 진행하고 있다. 상업 원격탐사시스템의 운영허가에 관한 규제개혁은 허가절차에 관한 프로세스를 대폭 개선해서 신청인의 행정부담을 경감하고 또한 허가심사과정에서 국가안보 등에 미치는 영향이 명백한 경우에만 허가를 제한하는 내용을 골자로 한다. 그러나 개인 우주활동의 자유 확대는 국가간 상이한 규제체제로 인해 국제법상 분쟁이나 위반을 초래할 수 있기 때문에 국제적인 차원에서 미국의 규제개혁 노력에 관심을 갖고 우주기술 및 우주산업의 수준에 맞게 신축적으로 적용 가능한 국제적 규범을 발전시키기 위한 노력이 필요하다.

그 동안 사이버 테러와 관련하여 우리나라에서 많은 양질의 지식이 축적되어 왔음에도 불구하고 몇 가지 매우 중요한 취약점이 지적될 수 있다. 그리고 이러한 취약점을 극복해 보려는 시도가 이 논문의 주요 논제이다. 기존 사이버 테러관련 논의나 연구를 살펴볼 때 아쉬운 점으로 파악되었던 사항은 사이버 테러와 관련된 여러 현상들이 빚어내는 미래의 안보환경에서 국가안보전략 개발이라는 거시적 프레임에서 사이버 테러문제를 접근하는 논의가 없었다는 점이다. 이 논문은 이러한 사항에 중점을 두고 사이버 테러에 대한 논의를 전개할 것이다. 바꾸어 말하면 이 논문의 목적은 안보위협의 한 양식으로서 사이버 테러가 던지는 국가안보위협의 의미를 재평가하고 미래안보환경에서 국가안보전략 개발이라는 틀 속에서 사이버 테러의 문제를 재조명 한다. 이 논의에서 다루는 사이버 테러에 관련된 몇 가지 쟁점들은 사이버 공간이 추가된 미래안보환경에서 국가안보의 전략적 접근 틀의 구성에 중요한 메시지를 전달한다. 미래 환경에서 사이버라는 새로운 특성을 가진 공간 환경이 국가안보와 사회 및 개인안전에 중요한 외부조건의 하나로 추가되었다는 사실을 직시하고 기존의 4차원에 사이버가 추가된 5차원 공간환경에서 어떻게 새로운 국가안보전략이 마련되어야 하는지에 대한 기본 전략 틀이 마련되어야 한다. 이러한 전제위에 미래의 기술진보의 양상과 방향이 파악되어야 하고, 위협의 주체와 성격과 유형이 분석되어야 한다. 사이버 테러의 위협과 성격은 이런 맥락에서 다루어져야한다. 한편 이러한 기반위에 다시 사이버 테러를 포함한 여러 미래사회에 예상되는 위협들과 위협 주체들에 대응하기 위한 방안들이 기능과 시스템 면에서 동시에 수립되어야 한다.
