NFV is a technology that allows network services to be controlled and managed in software by separating various net work functions (NFs) from hardware devices in dedicated network equipment and implementing them in a high-performance general-purpose server. Therefore, standardized virtualization of network functions is one of the most important factors. However, until the introduction of NFV to provide commercial services, there are many technical issues to be solved such as guaranteeing performance, stability, support for multi-vendor environment, ensuring perfect interoperability, and linking existing virtual and non-virtual resources. In this paper, we propose a method to provide an end-to-end network virtualization service based on OSM R2 in KREONET.

Cyber attacks are an important factor that determines the victory and defeat of Network-centric wars in which advanced weapon systems are highly interlinked. In addition the increasing dependability on software as its develop as the latest fighter is demanding enhanced security measures for fighter software to Cyber attacks. In this paper, we apply the DO-326A, which is an airworthiness security certification standard, to design a risk-based security threat assessment process by reflecting characteristics and operational environment of fighter aircraft. To do this, we add the following steps in security threat assessment stage of DO-326A's airworthiness security certification process. First, we derive security threats of fighter. And then, we scored the security threat in terms of possibility and impact on the fighter. Finally, we determine the security risk severity.

그리드는 고성능 컴퓨터, 대용량 데이터베이스. 각종 정보통신 첨단장비 등을 초고속 네트워크로 연동해 상호 공유하는 핵심기술과 운영체제를 말하며, 이를 효율적으로 활용하기 위해서는 자원의 특성과 사용자의 신원에 의해 제한적으로 액세스가 가능한 메커니즘과 신원이 확인된 사용자의 권한 유무를 검증할 수 있어야 한다. 따라서 사용자와 관리자 양방의 편리성과 안전성을 위해 그리드의 보안은 단일 인증 기능을 제공해야 하는데, 기존의 방식은 공개키 인증서 방식의 복잡한 알고리즘을 사용하므로 인증 시간이 오래 소요되며. 전체적으로 그리드 성능을 저하시키는 요인이 된다. 따라서 본 논문에서는 이를 해결하기 위하여 SAML을 이용한 그리드 단일 인증 보안 기법을 제안하고자 한다.

The interview for the selection of army officers had a lot of interview questions and topical content, so it was difficult to prepare for military officers applicants. Applicants who pass the written evaluation will be selected after passing the final interview. However, as the number of applicants is relatively decreasing due to the improvement of the treatment of the soldiers, it is expected that there will be a shortage of executives to operate advanced equipment in the future. To ensure that excellent applicants do not drop out of the final interview, we intend to provide interview-related data and suggest a unique interview direction for applicants.

Among the five promotion strategies of Defense Innovation 4.0(DI 4.0), the military structure/operation optimization strategy aims to innovate the military structure based on advanced science&technology(S&T), and to integrate advanced S&T in the field of defense operation such as education&training and human resource development. As the future battlefield expands to AI-based unmanned/robot combat systems, space, cyberspace, and electromagnetic fields, it is necessary to train officers with the capabilities required in these battlefields. It is necessary to develop capabilities from junior officers who will lead the future battlefield to operating core advanced power based on the 4^th industrial revolution S&T. We review the education system of the military in universities and propose a method of redesigning the education system that is compatible with DI 4.0 and can develop technology-intensive capabilities based on advanced S&T. We propose a operation plan of major and extra-programs that can develop the capabilities of junior officers required for the future battlefield, and also suggest ways to support the army's practical training.

With the growth of airline management, as well as computer and IT security, the international trade in this modern society has been rapidly increasing, Along with the advancing, airplanes have become a universal means of communication. However, the complications associated with airplane safety have also been brought up as a result, the most concerning of which is terrorism. One of the main counterplans for preventing terrorism is Ground security activities the core of Ground security activities is absolute safety for passengers in both passenger terminal and freight terminal. Subastral security refers to physical protection, proximity control and 100% security search and freight guarding of the passengers' possessions, and the personnel's duties to perform such jobs are be! coming more crucial. On the other hand, Airport security check has bee n gradually developing since the 1960's, when hijacking began to take place. Although the airports have been providing more safe and comfortable services to their customers, terrorism is still happening today. When Ground security activities is minute, the users feel displeasure and discomfort, yet considering solely their convenience can brings problems in achieving safety. Since the 9.11 terror in 2001, the idea of improving and strengthening airport security was reinforced and a considerable amount of estate is being spent today for invention and application of new technology. Various nations, including the United States, have been improving their systems of security through public services; public police department is actively carrying out their duties in airports as well. In San Francisco International Airport, private police department is in charge of collection of data, national events, VIP protection, law enforcement, cooperation within facilities, daily-based patrol and traffic control. Under guidance and supervision of national organizations, such as TSA, general police department interprets X-Rays, operates metal detectors, checks passports or IDs and observes reactions to explosives. Under these circumstances, studies about advancement of cooperation and duties of general police department and private police department necessitated: especially about private police department and their training for searching equipments, decrease in number of turn over rate, invention of technology and prior settlement in estate for security. The privacy of the public, who make up the major population of airport passengers, must also be minimized. In the following research, the activities of police departments in San Francisco International Airport will be analyzed in order to understand recent actions of the United States on airport security.
