AAA(Authentication, Authorization, Accounting) protocol is a framework that propose functions of AAA on multiple networks and platforms. AAA protocol is extending from previous RADIUS protocol to Diameter protocol. There are some Diameter applications for variety purpose. Diameter CMS Application makes Diameter messages more secure by using PKI. Diameter CMS Application establish DSA(Diameter Security Association) for end to end security. However the Application has some problems to establish DSA(Diameter Security Association), which can make Diameter system unstable. If one system lose DSA information for some system error - for example, reboot -, the secure communication between two nodes may not be possible. At the application such as MIP, even user registration can't be done. In this paper, we propose a mechannism for DSA re-establishment, and also show the result of the implementation.

Private security guards are not given special legal privileges to the general public, and holds the same legal status. However, the private security industry has been the expansion of business areas, but some legal rights to bring a limited time you can claim that. In this study, major countries such as Japan, the United States and comparative analysis of the legal status of the security guards and private security guards in Korea about the legal status of the current law on the guards private security law Korea by analyzing the legal status of private security guards to the issue of the legal status and thereby derive an alternative proposes a purpose.

Up to now, the security system in Korea has been developed from the human security system to more efficient mechanical security system. The mechanical security system has its advantages over the human security system in terms of economy and operation. However, as there are weaknesses in the use of mechanical security equipment such as erroneous alarm sounds, the studies have been done to improve them. This paper tries to suggest how to improve the mechanical security system based on the results of the study on the weakness of the mechanical security obtained through AHP technique.

Private security industry employers in Korea has not concerned with the importance of training and education by lack of recognition and has been passive about qualified guards. And the authorities supervising and the administrating the guards has not recognized the importance of private security and has neglected the training of the guards. Korea has been operated the guard-instructor system for the acquiring the specialization of the security personnel since 1997, but there has been many problems. This study reviews the guard-instructor system in Korea comprehensively and suggests the efficient operation method of that system.

Because security of Internet of Things(IoT) products and others is poor, there are many hacking incidents To prevent security threats, it is important for companies to first make products with high security levels and choose products that are safe for users. In response, the Korea Internet & Security Agency is testing the security of IoT products and linked mobile apps to impose ratings. Security certification service is a service that tests IoT products and linked mobile apps to ensure certain levels of security and issues certificates when they meet the criteria. It can induce autonomous security enhancement of IoT products, contribute to strengthening security capabilities of IoT companies in Korea and vitalizing their overseas advancement, and have the expected effect of resolving public anxiety over IoT products. In this study, the criteria for IoT security certification are presented, but the importance priority is sought to be derived for assessment items that need to be strengthened. This will help to provide guidelines that can contribute to strengthening the security capabilities of domestic Internet companies and boosting their overseas advancement.

I Study on the security measures of the World Cup Korea and Japan jointly in 2002. The paper, purporting to consider security counterplans, comprise five chapters. Chapter I which sets out purpose, scope and method, is followed by chapter II, dealing largely with the legislations and importance on the security measures of the 17th FIFA World Cup in 2002. Chapter III concerns the security environment -internal environment, external environment- and the highlights accidents and events of history on the FIFA World Cup. Chapter IV consider security measures of the World Cup Korea in 2002. It is followed by concluding observation made in chapter V. To be operated security systems effectively, these need to be regulated according to a security measures organizations, security facilities and equipments, security plan and protective force, security operations and so forth.

Security has been considered one of the most critical issues for managing IT resources in many organizations. Despite a growing interest and extensive research on security at various levels, little research has focused on the comparison of security knowledge levels between different cultures. The current study investigates and compares the security knowledge level between Korea and the U.S. Based on the literature review of spyware, Hofstede's cultural dimensions, and security knowledge, this study identifies three constructs (i.e., security familiarity, spyware awareness, and spyware knowledge) to examine the difference of security knowledge levels between Korea and the U.S. Six hundred ninety-six respondents from Korea and the U.S. participated in the survey, and an in-depth analysis based on analysis of covariance (ANCOVA) was carried out. The results show that the levels of security familiarity, spyware awareness, and spyware knowledge are significantly lower in Korea than in the U.S., as expected. These findings present a significant association between national culture and security knowledge, and the degree of individualism (or collectivism) plays an especially critical role in the perception of security. A number of implications for academia and practitioners emerge. Limitations and future research directions are discussed in the conclusion.

Among the various services for mobile banking, user authentication method using bank security card is still very useful. We can use mobile banking easily and safely in case of saving encoded security codes in smart phone and entering codes automatically whenever user authentication is required without bank security card. In this paper automatic recognition algorithm of security codes of bank security card is proposed in oder to enroll the encoded security codes into smart phone using smart phone camera. Advanced adaptive binarization is used for extracting digit segments from various background image pattern and adaptive 2-dimensional layout analysis method is developed for segmentation and recognition of damaged or touched digits. Experimental results of proposed algorithm using Android and iPhone, show excellent security code recognition results.

The problems of current network security system, separated by a single element is checked. To improve this, this thesis is to find vulnerabilities in the network security systems, and network security systems, security equipment, organic to make sure each works is a comprehensive review. Automation also offers a way to check it, it was implemented.
