With the changing safety services and social order systems accompanied by the economic development and changing public security environment since the Chinese economic reform, the security service industry in China is growing daily and related problems are increasing. For the Chinese security service market to be activated, the monopoly of security services by the public security agencies must be removed. In addition, the research and development, expansion, and applications of safety and crime prevention technologies regarding the safety and protection of exhibition, sales, culture, sports, commerce activities, combinations of safety technologies and crime prevention processes, the provision of relevant technical operations, and the expansion of security service areas are required. Furthermore, the administration rights, property rights, and business management rights of security companies must be separated, the security headquarters must be integrated and coordinated for optimization of various resources solely by market needs, and their rights and affiliation relations must be clear. Besides, the competitiveness of security companies in the security service market must be enhanced by unifying the business management, and optimizing and sharing their resources. The security service ordinances of China that have been implemented now must be applied realistically, methods to activate the true market economy for security services must be researched, and various ordinances related to security services must be realigned in line with the characteristics of security services. Finally, for the mutual cooperation system between public and private security services, the public security agencies must acknowledge the importance of private security services and the status of security service providers in crime prevention and social order maintenance. They must establish partnership relations with each other beyond the unilateral direction and management system for security services and drive with positive attitudes the security service industry which is still in its infancy.

Recently, the introduction of Cloud Managing Security Services System to respond to security threats in cloud computing environments is increasing. Accordingly, it is necessary to analyze the security requirements for the Cloud Managing Security Services System. However, the existing research has a problem that does not reflect the virtual environment of the cloud and the data flow of the Cloud Managing Security Services System in the process of deriving the requirements. To solve this problem, it is necessary to identify the information assets of the Cloud Managing Security Services System in the process of threat modeling analysis, visualize and display detailed components of the cloud virtual environment, and analyze the security threat by reflecting the data flow. Therefore, this paper intends to derive the security requirements of the Cloud Managing Security Services System through threat modeling analysis that is an improved existing research.

In Mongolia, the regulation related to the private security industry, the Law on Contracted Private Security Services, was legislated relatively recently. The Law on Contracted Private Security Services was enacted into law in Mongolia 16 years ago, in 2000. This regulation has undergone two amendments since its inception. However, new revisions still need to be made to ensure that this regulation is in line with internationally accepted standards and practices. This paper compares the existing private security regulations of South Korea and Mongolia. The purpose of this comparative study was to identify the weaknesses of and problems in the Mongolian regulation and propose amendments to the Mongolian regulation. The comparative study of the two countries' regulations showed and underscored an imperative need to make further amendments to the Law on Contracted Private Security Services. Specifically, the weaknesses of and problems in the Mongolian regulation at issue include the following: the level of accuracy in defining certain legal terms and providing the proper names for various regulations; stipulations which set forth the procedure for registering a private security company; provisions regarding operating a private security company; the details of eligibility and accountability requirements concerning chief executives and security service officers; and the scope of work provisions. This study proposes constructive amendments to strengthen the Law on Contracted Private Security Services.

Internet Services have security issues. To prepare proper security measures for these security issues, security level setting is positively necessary. Until now, we use a security level with CIA (Confidentiality, Integrity, and Availability) Security Levels. However, CIA Security Levels has problems with ambiguous measures for the middle level of security setting. Moreover, security level overlap occurs, in some cases, when user authentications are not done. Additionally, there exist some levels among CIA Security Levels which cannot be applied to Internet services. In this paper, new security level model, CIAA Security Levels with deletion of ambiguous middle level of security setting and addition of authentication to one of security level setting factors, is proposed. The CIAA Security Levels model can be applied to more concrete security measures than CIA Security Levels. The proposed Security Levels model is applicable to almost any on-line services and it can be applied to new online services.

The purpose of the study is to contribute to the positive development of blockchain technology by providing data to examine security vulnerabilities and threats to blockchain-based services and review countermeasures. The findings of this study are as follows. Threats to the security of blockchain-based services can be classified into application security threats, smart contract security threats, and network (P2P) security threats. First, application security threats include wallet theft (e-wallet stealing), double spending (double payment attack), and cryptojacking (mining malware infection). Second, smart contract security threats are divided into reentrancy attacks, replay attacks, and balance increasing attacks. Third, network (P2P) security threats are divided into the 51% control attack, Sybil attack, balance attack, eclipse attack (spread false information attack), selfish mining (selfish mining monopoly), block withholding attack, DDoS attack (distributed service denial attack) and DNS/BGP hijacks. Through this study, it is possible to discuss the future plans of the blockchain technology-based ecosystem through understanding the functional characteristics of transparency or some privacy that can be obtained within the blockchain. It also supports effective coping with various security threats.

Currently many central administrative agencies, municipalities and public and private institutions operate Managed security services to cope with cyber security incidents. These entities exert efforts in operating efficiencies rather than introduction of services as they used to. Accordingly, quite a few policies, directions and guidelines have been established for stable operation of Managed security services. Still, Managed security is operated by individuals, whose competencies influence the quality of Managed security services to a great extent. In this respect, the present article examines Managed security technology and methods and describes evaluation methods and examples relevant to human competencies, so as to seek for some potential courses for further development as well as more efficient approaches to human resource management in terms of institutional Managed security services.

The preliminary security assessment is an information security process to analyze security weaknesses before beginning of services. Discovering security weakness through preliminary security assessment is highly required because it costs much when security incident occur in the middle of service operation. However, this assessment is not widely spread in the online game service domain yet. In this paper, we summarize the security risk existed in the online game service, and we classify the security requirements related to the each risk. Also, through the case study, we evaluated the effectiveness of preliminary security assessment in this domain. In addition, we suggest checklists that should be reviewed once in game-client side, network-side and game-server side for the purpose of security enhancement.

「Security Services Industry Act」made in 1976 for the purpose of contributing to the good operation of services industry by establishing the requirements for promotion, development and systematic management of services industry has been since 26 times of overall revisions. Period division of private security through overall revision of 「Security Services Industry Act」 can be roughly divided into three periods. The first is a settlement period. It is a period when the present five business areas were completed rom 1976 to 2001. Beginning with facility and escort security in 1996, five types of jobs have been prepared. so far by adding personal protection in 1996, and machine and special security in 2001. The second is a quantitative growth period. It is a period when quantitative development is made on the institutional basis. As various culture, sports and arts events are increasing based on the demand of security services due to an increase in the people's sense of security, quantitative development was made, which additionally influenced the downward trend of capital and the possibility of having two jobs through revisions. The third is a qualitative growth period. From 2013 to the present is a period when quantitative growth has slowed and qualitative growth has been made. After the period of quantitative growth, the growth slowed down. However, by raising the criteria for permission of services industry through creation of a rule for the group civil petition, by raising capital, by institutionally compensating for diverse punishment regulations, by realizing the training hours for new security guards, by permitting private education, etc, the reliability and professionality of a security guard job has been to be recovered.
