Defence Security Command is the only military intelligence and investigation agency which is in charge of safeguarding military information and investigating specific crimes such as subversion and disloyalty in military. While the presidential security provided by Defence Security Command, along with Presidential Security Service(PSS) and the police, forms one of three pillars sustaining presidential security, its works and activities have been rarely known to the public due to the military confidentiality. This study looks into some data specialized into the presidential security among works of Defense Security Command by using various resources such as biographies of key people, media reports, and public materials. It reviews the presidential security works in a historical sense that the works have developed and changed in accordance with the historical changes of Defense Security Command, which was rooted in Counter-Intelligence Corps (Teukmubudae in Korean) in 1948 and leads to the present. The study findings are as follows. First, when the Korean War broke out in 1950 and since then the South Korea was under the threat of the North Korean armed forces and left wing forces, Counter-Intelligence Corps(Bangcheopdudae in Korean) took the lead in presidential security more than the police who was in charge of it. Secondly, even after the Presidential Security Office has founded in 1963, the role of the military on presidential security has been extended by changing its titles from Counter-Intelligence Corps to Army Security corps to Armed Forces Security Command. It has developed their provision of presidential security based on the experience at the president Rhee regime when they could successfully guard the president Rhee and the important government members. Third, since the re-establishment into Defence Security Command in 1990, it has added more security services and strengthened its legal basis. With the excellent expertise, it played a pivotal role in the G20 and other state-level events. After the establishment of the Moon Jaeinin government, its function has been reduced or abolished by the National Defense Reform Act. However, the presidential security field has been strengthening by improving security capabilities through reinforcing the organization. This strengthening of the security capacity is not only effective in coping with the current confrontation situation with the hostile North Korean regime, but also is important and necessary in conducting constant monitoring of the military movement and security-threat factors within military during the national security events.

It is needless to say that the port security is very important owing to the geographic setting of Korea and the possibility of the provocation by North Korea. In addition, The security management is necessary for the port and the domain of maritime to block the inflow from overseas because of the increase of international crime as terrorism. The training system for port security guard should be constructed to secure the specialization of the manpower for the efficient port security management. But the training system of port security manpower is not unified and the training is not carried out, therefore it is necessary to improve the training system of port security manpower. In this study, the improvement plan of training system is suggested as follows. First, the unification of the legislation of port security should achieved to establish the guidance of training for port security guard. Second, the specialized training per activities should be done. And lastly, the qualification system should be introduced for the specialization of port security manpower.

The purpose of the present study is to empirically examine factors that affect the information security awareness and perceived information security risk of employees of port companies. In particular, in order to identify factors that affect the perceived information security risks, we investigated the relation of assets, threats, and vulnerabilities to it, using the risk analysis methodology. With A total of 252 valid questionnaires, we also performed the structural equation modeling analysis using AMOS. It was found that first, there was no meaningful relationship between the information assets and the perceived information security risk in the case of employees of port companies. Second, threats and vulnerabilities turned out to have positive influences on the perceived information security risk. Finally, there was a positive relationship not only between the information security awareness and the information security education, but also between the information security awareness and the intention of information security. However, there was no meaningful relationship between the information security concern and the information security awareness.

통신기술의 급속한 발전으로 네트워크 환경이 광대역통합망으로 진화되어가고 있다. 이로 인해 개별 네트워크에서 운영되던 IT서비스들 또한 광대역통합망 환경에서 빠른 속도로 융합되고 있다. 하지만, 개별 네트워크에서 운영되던 기존의 IT서비스들이 광대역통합망에서 서로 융합되어 신규 IT 서비스를 생성하는 과정에서 보안요소가 적용되지 않을 경우에 신규 IT서비스의 안정성 및 신뢰성이 떨어질 수 있다. 이러한 문제점을 해결하기 위해서, 본 논문에서는 신규 IT 서비스의 기반구축 및 운영이전인 서비스에 대한 기획 및 설계시에 필수적인 보안대책 제시하여 서비스 운영이전에 보안대책을 적용할 수 있도록 함으로써, 신규 IT 서비스의 안정성과 신뢰성을 확보할 수 있는 방법으로 정보보호사전평가 모델을 제시하고, 이 모델을 RFID 서비스에 적용한 예제를 설명한다.

Recently, security incidents are growing rapidly in which internal employees let the drawing leak out to competitors or other countries. This type of security incidents has a characteristic that it occurs less frequently than other types of security incidents such as network or server security incident, but the damage is a lot more serious. The existing information security technologies to prevent internal information from being leaked out are only applicable to general documents(office documents, web pages and image files in which data are encrypted one by one). However, architectural drawings made up of collection of files with various formats(extensions) have problems with the process speed of en(de) cryption and accuracy, so the developments of security technologies by new methods are required. In this study, we design and develop a security technology based on work area with which users can protect the leakage of critical information in the kernel level while maintaining their work environment when they have to use sharing information that cannot be managed by the unit of file. As a result, we developed the "Virtual Secure Disk" which allows only authorized users and applications to have an access to drawings, and have verified its security by applying it to the actual company.

Existing research on security technology related to network attack response has focused on research using hardware network security technology, network attacks that wiretap and wiretap network packets, denial of service attack that consumes server resources to bring down the system, and network by identifying vulnerabilities before attack. It is classified as a scanning attack. In addition, methods for increasing network security, antivirus vaccines and antivirus systems have been mainly proposed and designed. In particular, many users do not fully utilize the security function of the router. In order to overcome this problem, it is classified according to the network security level to block external attacks through layered security management through layer-by-layer experiments. The scope of the study was presented by examining the security technology trends of edge routers, and suggested methods and implementation examples to protect from threats related to edge router-based network attacks.
