A look back at the history of war reveals that leaders/nations which were able to recognize beforehand the change in weaponary or the concept of implementing war achieved victory in war(battle) while those that were not able to do so lost. Along with the development of civilization, so too did the characteristics of war : from the first wave of war (ancient, Napoleon's war)$\rightarrow$ the second wave of war (The first and second World War) $\rightarrow$ to the third wave of war (The Gulf War, and the War in Iraq). Especially notable was the American led victory earned in the Afghanistan and Iraq wars which applied the Rapid Decisive Operations(RDO) concept according to the Effects Based Operations(EBO) following the Gulf War and 9.11. This is the time when methods of warfare is changing through development in military science technology and military innovation and when the change of the defense paradigm including those of the Korea - U.S. alliance is required. We should therefore prepare for the future by delving into the analysis of American Modern warfare and learn from it.

The growing number of threats to society through the uncontrolled distribution of information is forcing library communities in many countries to reconsider their views on free access to collections. Based on the content of numerous documents of international importance, it can be concluded that in any democratic country access to information is one of the most important human rights, along with the right to life, liberty, and security of person. However, the state has the right to restrict citizens' access to information within the framework of existing legislation. Constantly, restrictions on access to information are established in order to protect the ethical foundations of the constitutional order, morality, health, rights, and legitimate interests of others, to ensure the country's defense and state security. It goes without saying that each country has the right to independently decide where the boundaries lie between permitted and prohibited information, including printed information, contained in library collections. This article describes three levels of access restriction: foreign, state, and regional. The authors have analyzed the legal and regulatory documents that govern libraries, as well as the reasons and methods of limitation. A comparative analysis of the restriction of access to information in the countries of Europe and Asia is presented.

DDoS attacks make people can't using normal internet service, because DDoS attacks cause exhaustion of network bandwidth or exhaustion of computer system resources by using many personal computers or servers which already infected computer virus from hackers. Recent DDoS attacks attack government brach, financial institution, even IT security company. IT security companies make Anti-DDoS product for defense from DDoS attack. But, There is no standard for BMT of Anti-DDoS product. In this dissertation, Anti-DDoS product quality characteristics of the survey analysis to evaluate them by comparing the assessment items were derived.

As the 4^th Industrial revolution technology develops, it is expected that future technologies will be used in the military. The Army is developing the Army TIGER 4.0 system, which means innovative changes in mobile, networked, and intelligent ground forces. In order to utilize future technologies, it is necessary to be able to transmit and receive large amounts of data between weapon systems, but there are limitations to supporting this through TICN and ANASIS. Therefore, in this paper, the information exchange requirements generated by the Army TIGER 4.0 battalion and the amount of traffic by communication layer are analyzed based on the battalion defense operation scenario to suggest information distribution capability of the future tactical communication system.

Malicious insider threats have increased recently, and methods of the threats are diversifying every day. These insider threats are becoming a significant problem in corporations and governments today. From a technology standpoint, detecting potential insider threats is difficult in early stage because it is unpredictable. In order to prevent insider threats in early stage, it is necessary to collect all of insiders' data which flow in network systems, and then analyze whether the data are potential threat or not. However, analyzing all of data makes us spend too much time and cost. In addition, we need a large repository in order to collect and manage these data. To resolve this problem, we develop an indicator-based behavior ontology (IB2O) that allows us to understand and interpret insiders' data packets, and then to detect potential threats in early stage in network systems including social networks and company networks. To show feasibility of the behavior ontology, we developed a prototype platform called Insider Threat Detecting Extractor (ITDE) for detecting potential insider threats in early stage based on the behavior ontology. Finally, we showed how the behavior ontology would help detect potential inside threats in network system. We expect that the behavior ontology will be able to contribute to detecting malicious insider threats in early stage.

In recent years, new and variant hacking of binary codes has increased, and the limitations of techniques for detecting malicious codes in source programs and defending against attacks are often exposed. Advanced software security vulnerability detection technology using machine learning and deep learning technology for binary code and defense and response capabilities against attacks are required. In this paper, we propose a malware clustering method that groups malware based on the characteristics of the taint information after entering dynamic taint information by tracing the execution path of binary code. Malware vulnerability detection was applied to a three-layered Few-shot learning model, and F1-scores were calculated for each layer's CPU and GPU. We obtained 97~98% performance in the learning process and 80~81% detection performance in the test process.

Among the network information services combined with a number of security technologies and required security policies, Infrastructure as a Service, a hardware plat-form service of Cloud Computing, has been provided since 2011. It is more or less similar to the existing central concentration method services, in terms of the specifications and technical aspects for given hardware category, but it is entirely different from them in that it overcomes the spatial limitations of specific network and targets the public network. Information security technology has also been prospering so that it could ensure the stability of offered hardware plat-forms. As currently supported hardware, Internet Data Center has been provided by virtualizing the previously offered servers and discs (backup discs), but the hardware plat-forms offered are somewhat limited. Meanwhile, the areas of security fields for offered services are confined to the center or include the TCP/IP-based SSL (Secure Sockets Layer) for the public network connected with clients, which shows that microscopic access security policies have been used. Therefore, this study was aimed to provide a realistic security mechanism for realizing defense policy, by expanding service areas into security devices and suggesting Diskless and Stateless security policy based high-speed synchronous network infrastructure.

Among many hacking attempts carried out in the past few years, the cyber-attacks that could have caused a national-level disaster were the attacks against nuclear facilities including nuclear power plants. The most typical one was the Stuxnet attack against Iranian nuclear facility and the cyber threat targeting one of the facilities operated by Korea Hydro and Nuclear Power Co., Ltd (Republic of Korea; ROK). Although the latter was just a threat, it made many Korean people anxious while the former showed that the operation of nuclear plant can be actually stopped by direct cyber-attacks. After these incidents, the possibility of cyber-attacks against industrial control systems has become a reality and the security for these systems has been tightened based on the idea that the operations by network-isolated systems are no longer safe from the cyber terrorism. The ROK government has established a realistic control systems defense concept and in the US, the relevant authorities have set up several security frameworks to prepare for the threats. This paper presented various cyber security attack cases and their scenarios against control systems, along with the analysis of countermeasures for them. Though this task, we attempt to identify the items that need to be considered when designing a domestic security framework to improve security and secure stability.

In recent years, the ROK military is promoting Defense Innovation 4.0 with the goal of fostering strong military based on science and technology equipped with artificial intelligence(AI) to prepare for the upcoming population cliff. In particular, at the present time of increased threats of North Korea, the South Korean military is seeking to deal with a decrease in military service resources through the introduction of a Scientific Guard System using advanced technology. TICN which is a core basic communication system to ensure the integrated combat capability of the ROK military is, however, limited to use as a based network for the emerging Scientific Guard System due to the narrow transmission bandwidth with widely spread poor reception area. To deal with this problem, this paper proposes TVWS-based Scientific Guard Systems with TVWS-based wireless network construction technology that has been available for free in Korea since 2017. The TVWS-based Scientific Guard System proposed in this paper, when compared to the existing wired network-based Scientific Guard Systems, has various advantages in terms of minimizing operational gaps, reducing construction costs, and flexibility in installation and operation.
