Command and control (C2) information is exploding as sensor and network technologies development. In the C2 are a, processing information on time is very important. If it is not possible to process all information on time because of resource limitation, higher priority information should be processed first. For this, recommendation system is available. Because it can select and present information suitable for each user among tons of information in the order of priority. This study extends the triple-metric priority criterion, which is widely used to implement military communication networks, to the quadruple-metric priority criterion, and proposes a C2 information recommendation system based on it, and shows it's feasibility through experiments.

본격적인 정보화시대를 맞아 정부에서는 정보화사회를 조기에 구현, 정착시키고자 행정,금융, 교육/연구, 국방, 복지등 5개 분야에 걸친 국가 기간망 구축사업을 위시하여 각종 정보화 정책 및 사업을 추진하고 있다. 그러나 국가정보화사회를 성공적으로 구현하기 위해서는 그의 인프라(Infra)인 지역별 정보화가 추진되어야 한다. 지역정보화는 이제 국가정보화사회를 구현하는데 필수적으로 거쳐야 할 중간단계로 인식되고 있다. 충북지역에서도 청주/청원 지역을 정보화의거점으로 삼아 지역데이타베이스를 구축하고 이를 공중통신망에 접속하여 주민들이 가정이나 직장에서 컴퓨터 단말기를 통하여 필요한 정보를 검색하고,주민간 상호정보교류는 물론 의견이나 제안을 해당 기관 및 단체에 알릴 수 있는 본격적인 지역정보통신 시대를 개막하고자 하는 계획을 추진하고 있다. 그러나 지역정보란 개념과 범위가 방대하고 이용집단에 따라 정보 수요가 다양한 차이를 보일 수 있기 때문에 단번에 지역의 모든 집단의 정보수요를 충족시킬 수 있는 데이터베이스를 구축한다는 것은 불가능한 것이다. 따라서 지역 데이터베이스는 단계적이며 일관성을 유지한 추진 계획과 지속적인 구축노력이 필수적이다. 이러한 배경하에 본 소고에서는 정보항목별 데이터베이스 구축의 우선순위를 파악하고 데이비스의 기술수용모델을 중심으로 사용자에 대한 기술 수용태도를 알아보기 위해 검증을 시도하였다.

Cyber space is a place where free activities are guaranteed. However, it is also true that not all individuals and countries strive for peaceful cyberspace, and that there is a growing tendency to gain unfair advantage through this space. Therefore, the state should reform laws and institutions to keep cyberspace safe. By establishing the "Basic Law on Cyberspace" which includes the law of the state law on cyberspace, it is necessary to be able to recognize and respond to the direction of the national legal discipline on cyberspace. The development of digital forensics is an urgent task due to the rapid development of IT. However, if the law is delayed for various reasons, some of the existing laws should be amended to improve the stability of the law in accordance with the circumstances. To this end, it is necessary to revise the "Information and Communication Infrastructure Protection Act", "Information and Communication Network Enhancement and Information Protection Act", "Integrated Defense Law", "Establishment of Defense Information Infrastructure Infrastructure and Defense Information Resource Management Act".

The ROK Army is promoting cutting-edge, future-oriented military development such as a mobile, intelligent, and hyper-connected Army TIGER system. The future infantry brigade plans to increase mobility with squad-level tactical vehicles to enable combat in multi-domain operations and to deploy various weapon systems such as surveillance and reconnaissance drones. In addition, it will be developed into an intelligent unit that transmits and receives data collected through the weapon system through a hyper-connected network. Accordingly, the future infantry brigade will transmit and receive more data. However, the Army's tactical information communication system has limitations in operating as a tactical communication system for future units, such as low transmission speed and bandwidth and restrictions on communication support. Therefore, in this paper, the information distribution capability of the future infantry brigade is presented through the offensive operation scenario and M&S.

ICT infrastructure is electronic control systems or communication network related to national security, public administration, defense, policing, finance. Water resources sector has been building a system of control that can be performed electronically, communications, management, energy, and other work-related. Water resources sector has been a paradigm shift in water management and the control system is integrated into a single network. The control system security vulnerabilities are exposed - other control networks, business networks, linking with outside agencies, etc. Cyber terrorist society can cause a huge mess economically, The importance of security for control systems is becoming. In this paper, ICT infrastructure - the water resources in the field of control systems will analysis security measures.

At present, TICN has been developed and distributed for military command control. TICN is known as the 3.5G mobile communication technology based on WiBro, which shows technical limitation in the field operation situation. Accordingly, the drone-type base station platform is attracting attention as an alternative to overcome technical limitations such as difficulty in securing communication LoS and limiting expeditious network configuration. In this study, we performed simulation performance evaluation of drone-type base station operation in 28 GHz that is considered most suitable for cellular communication within mmWave frequency band. Specifically, we analyzed the changes in throughput and fairness performance according to radio resource management policies such as frequency reuse and scheduling in multi-cell topology. Through this, we tried to provide insights on the operation philosophy on drone-type base station.

As tactical networks are gradually shifting toward IP-based flexible operation for diversified battlefield services, QoS(Quality-of-Service) coordination for service differentiation becomes essential to overcome the heterogeneous and scarce networking resources limitations. QoS coordination for tactical network traffic should be able to monitor and react the dynamic changes in underlying network topology and service priorities. In this paper, by adopting the emerging cloud-native service mesh concept into tactical network context, we study the feasibility of intelligent QoS coordination by employing tactical service mesh(TSM) as an additional layer to support enhanced traffic quality monitoring and control. The additional TSM layer can leverage distributed service-mesh proxies at tactical mesh WAN(Wide Area Network) nodes so that service-aware differentiated QoS coordination can be effectively designed and integrated with TSM-assisted traffic monitoring and control. Also, by validating the feasibility of TSM layer for QoS coordination with miniaturized experimental setup, we show the potential of the proposed approach with several approximated battlefield traffics over a simulated TSM-enabled tactical network.

The drone-type base station will be an optimal platform as a way of information sharing for efficient operation of the military force due to their high network flexibility. It is expected that the characteristics of the drone-type base station which would freely adjust the altitude can be used to offset the propagation attenuation characteristics of the millimeter-wave frequency band by securing the stable Line of Sight. In this paper, we proposed a framework for evaluation drone-type base station that can be utilized as a future military communication network by performing modeling for performance analysis that can reflect various factors.
