Chatbot services are used in various fields in connection with AI services. Security research on AI is also in its infancy, but research on practical security in the service implementation stage using it is more insufficient. This paper analyzes the security requirements for chatbot services linked to AI services. First, the paper analyzes the recently published papers and articles on AI security. A general implementation model is established by investigating chatbot services provided in the market. The implementation model includes five components including a chatbot management system and an AI engine Based on the established model, the protection assets and threats specialized in Chatbot services are summarized. Threats are organized around threats specialized in chatbot services through a survey of chatbot service managers in operation. Ten major threats were drawn. It derived the necessary security areas to cope with the organized threats and analyzed the necessary security requirements for each area. This will be used as a security evaluation criterion in the process of reviewing and improving the security level of chatbot service.

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.

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.

Cloud computing is a widely used technology that has changed the way people and organizations store and access information. This technology is quite versatile, which is why extensive amounts of data can be stored in the cloud. Furthermore, businesses can access various services over the cloud without having to install applications. However, the cloud computing services are provided over a public domain, which means that both trusted and non-trusted users can access the services. Though there are several advantages of cloud computing services, especially to business owners, various challenges are also posed in terms of the privacy and security of information and online services. A kind of threat that is widely faced in the cloud environment is the on/off attack. In this kind of attack, a few entities exhibit proper behavior for a given time period to develop a highly a positive reputation and gather trust, after which they exhibit deception. A viable solution is provided by the given trust model for preventing the attacks. This method works by providing effective security to the cloud services by identifying malicious and inappropriate behaviors through the application of trust algorithms that can identify on-off attacks.

This study proceeded to examine the cause of the continuous secret information leakage in the firms. The purpose of this study is to find out what type of security among administrative, technological and physical security would have important influence on firm's security performance such as the security-incident response competence. We established the model that can empirically verify correlation between those three types of security and the security-incident response competence. In addition, We conducted another study to look at relation between developing department of security in the firms and reaction ability at the accidents. According to the study, the administrative security is more important about dealing with the security-incident response competence than the rest. Furthermore, a group with department of security has better the security-incident response competence and shows higher competence in fixing or rebuilding the damage. Therefore, this study demonstrates that investing in administrative security will be effective for the firm security.

The proposed conceptual framework is based in the relationships among knowledge of personal information security, trust on the personal information security policies of parcel delivery service companies, privacy concern, trust in and risk of parcel delivery services, and user satisfaction with parcel delivery services. Drawing upon both cognitive theory of emotion and cognitive emotion theory that complement each other, we propose a research model and examine the relationships between cognitive and emotional factors and the usage of parcel delivery services. The proposed model is validated using data from customers who have previously used parcel delivery services. The results show a significant relationship between the cognitive and affective factors and the usage of parcel delivery services. This study enhances our understanding of parcel delivery services based on the consumers' psychological processes and presents useful implications on the importance of privacy and security in these services.

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.
