Damage caused by ransomware has continued to increase since last year, but cyber operations are managed without any separate classification of ransomware types in the military's guidelines for carrying out cyber operations. However, unlike other malware, ransomware is a threat that could paralyze all defense operations in one moment, and the military should reevaluate ransomware and take countermeasures. Accordingly, this paper aims to analyze the assets, vulnerabilities, and threats related to defense information service based on information security risk management, and propose alternatives to ensure continuity of defense work from ransomware threats.

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.

ROK and the United States finally reached accord on the controversial transition of Wartime Operational Control on February, 2007, and ROK Government needs to strengthen the role of supporting for the comprehensive threats of futuristic warfare. The crucial point of the supporting for Military Operation depends on the nation's mobilization capabilities. For the effective mobilization the following facets can be improved further. First of all, the organizational integrity of the mobilization network within the government can be bolstered along the vertical command chain. The process of mobilization must be improved and it is import to utilize the information system. On the other side the government plan to distribute timely the mobilized resources must be made up for the weak points and developed continuously. We can expect these points to be improved steadily with the execution of the National Defence Reform 2020.

As the IT service environment grows, it is critical in terms of IT service quality to minimize the occurrence of failures due to changes in applications and to diagnose and recover in a short period of time how failure will affect the business. Thus, the Defense Acquisition Program Administration (DAPA) has been building and operating ITSMs to implement IT service management in a leading manner. Information Technology Service Management (ITSM) is divided into events, obstacles, changes, versions and setup management to ensure flexibility and stability in service delivery. It is also operated separately from service level, availability, capacity, financial and IT service continuity management to ensure service quality and cost efficiency. Based on ITSM military service history, this study looks at the impact of quality of service on value, satisfaction, and trust. The results of the analysis are highly valuable for future ITSM implementation and operation.

In order to restore the Hwangsanbeol Combat at present, it is necessary to make a close examination on the name of the military cops, the number of units, and the numerical strength, an unit organization, and a combat formation. Based on Samguksagi, Samgukyusa, other historical documents and military history information, I tried to restore the Hwansanbeol Combat as follow. The Shilla, at the 7 year of Mooyeol Dynasty, AD. 660, maintained 35 military units. The Shilla committed18 military units from among 35 units to battle against Baekje at the 7 Year of Mooyeol Danasty. The names ofmilitary units are as follow: 1) Daedang, 2) Sangjoojeong, 3) Hajoojeong, 4) Seodang, 5) Nangdang, 6) Eumlihwajeong, 7) Samryanghwajeong, 8) Sosarnjeong, 9) Namcheonjeong, 10) Leehwahaejeong, 11) Kaegeumdang, 12) Geupdang, 13) Nodang, 14) Woonjaednag, 15) Chungdang, 16) Suktoodang, 17) Gwidang, and 18) Soogun. The numerical strength, which the Shilla maintained at the year of A.D. 660, was total 106,353 persons from 35 military units. Shilla committed 57,433 military personnel to combats against the Great Baekche. Ground Forces from the 57,433 personnel were 58,343 persons, and the naval forces were 9,100 persons. Finally, 2,602 persons from among the 9,100 naval forces were only combating forces, and non-combat forces were 6498 persons.

None of the recent cases of military secret leakages have leaked internal information using networks. This is because the Internet and the Intranet are physically separated, and has a difficult process when transmitting and receiving data through the Internet. Therefore, most of the leaked paths are to copy and hand over secrets, shoot and send them with a smartphone, or disclose after remembering them. So, the technology of blocking and detecting military secret leakages through the network is not effective. The purpose of this research is to propose a method to prevent information leakage by focusing on the insider behaviors, the subject of leakage, rather than the military secret. The first is a preventive measure to prevent the leakage behavior of military secrets, the second is to block suspicious access to the military secret data, and the last is to detect the leakage behavior by insiders.

The limits of current DN(Defense networks), private and closed network, become to reality; for Example, high expense of construction and maintenance of networks, restriction of new subscribers on DN. Therefore, a network using web environment that reflect fast development of If and IS(Information Security) technology is demanded for MND. Meeting the requirement of reliable IS system and extension and improvement of DN using common network, we can reduce the expense to extend, maintain, repair DN, form the environment that makes military business cooperate better with civil company and government agency, advance implementing Defense computing and networking service for field small size units that was a exception of Defense digitalization. But it is essential to construct DN based on common network that there are security requisites; confidentiality, integrity, availability, efficiency, log, backup, restoration, that have to be realized at demanding level for IS. This thesis suggested four measurements; replacement DN with common network to resolve the requirements of building new network and improvement of performance for private DN, linkage with common network for new requirement, distribution of traffic using common network, configuration of DN using Internet and Proposed a refinement of IS management organization to treat security threat of common network flexibly, and LAN IS standard model of DN based on the web environment.
