Each organization installing and operating multimedia system, to achieve the goal of organization, should decide security level, implement security countermeasure, and manage these countermeasures to keep the effects. To decide and manage security level of multimedia system, the first, organizations must be able to decide security level, and then, organizations must establish procedures for building security countermeasures according to security level. For the next step, organizations must be able to select areas where security countermeasures should be applied, and the last, organizations must be able to evaluate and improve the effect of security countermeasures. In this paper, based on the analysis of threat to multimedia system and the consideration for multimedia assets, we propose a method for deciding security level of multimedia system.

Recently, the necessity of systematic security management system that consider company' character and environment has appeared because of increasing security accident continuously in domestic companies. However, most of companies has applied to only K-ISMS which is existing information security management system, although They are different from object, purpose and way of security level evaluation by companies. According to this situation, Many experts have questioned that there are many problems with effectiveness of introducing security management system. In this study, We established definition of information security management system, industrial security management system and research security management system through analysis of previous study and developed evaluation item which can implement security in whole industry comparing and analyzing the control items of them. Also, we analyzed existing security level evaluation and suggest design direction of industry-centric security level evaluation model considering character of industry.

In this study, the scope of previous logistics security were focused only on port and ship. Because of it now extends to the overall (export and import) supply chain areas and in regards with supply security programs in the international level, it reviewed supply chain security programs categorized them into 'ships and port security system', 'container screening system', 'logistics chain authorization system' which are expanded to be adopted in the international level. The major features of those programs are summarized as in building risk management system, providing information ahead, selectivity test and benefits to AEO authorized companies in the customs administration level. The government and companies which are to ensure supply chain security and trade facilitation in order to cope actively with international customs administrative atmosphere need to do the followings : First, they need to build an intra-government integrated supply chain security and make efforts to conclude AEO MRA in order to increase trade competitiveness among major trading countries. Second, they need to build supply chain risk management system in order to enhance management performance through overseas market and company level strategy to obtain and maintain AEO authorization in the company level.

In recent years The importance of information security management for securing information collection and analysis, production and distribution is increasing. Companies are assured of confidence in information security through authentication of information Security Management System. However, level assessment and use of domains that make up the management system is limited. On the other hand, the security maturity model is able to diagnose the level of information protection of the enterprise step by step. It is also possible to judge the area to be improved urgently. It is a tool to support goal setting according to the characteristics and level of company. In this paper, C2M2, which is an example of security maturity model, is compared and analyzed with Korea Information Security Management System certification. Benchmark the model to check the level of information security management and derive the priority among the items that constitute the detailed area of information security measures of ISMS certification. It also look at ways to check the level of information security management step by step.

In the paper, we designed an automatic security diagnostic evaluation System(SeDES) based on a security diagnostic evaluation model(SeDEM) for an organization's security assurance. The SeDEM evaluates a security level of an organization quantitatively by a security evaluation formula which is composed of security variables and security index as applying the statistical CAEL model for evaluate risk level of banks. The SeDES has a good expandability as changing security variables according to an organization scale, characteristics and so on. And it also has a excellent usage because it inputs only numeric data got from statistical technique to security index. We can understand more a security level correctly than the existent risk assessment system because it is possible to assess quantitatively with an security grade as well as score. analysis.

Recent increase of commercial network Integration to World Wide Web(WWW) shifts an ordinary commerce to electronic environment. This draws more people to examine re-assurance of their secure transaction. This study investigates current status of security methodology for Electronic Payment System and extracts important axis of security level for electronic payment. Using these axis as security evaluation criteria, the research proposes a security matrix which consists of four different level of security granularity, hence allowing evaluation of a nation-wide credit card based payment system. Feasible usage of this matrix contributes to security analysis of the electronic system as whole, hence providing better secured electronic environment.

Currently, the evaluation technology for the security systems of risk analysis level measurement is maintained by only the developed countries including U.S and U.K, and the evaluation technology and its infrastructure are insufficient for the evaluation technology of security threat analysis level measurement in Korea. Therefore this paper presents the development of the security control items and the evaluation tool(ISSPET) for the security level performance. It is expected to evaluate the security management level of the current system and its security environment through analyzing the security management level of security systems using ISSPET.

Purpose: The purpose of this study is to design a x-ray screening rating system to improve X-ray screening ability, which is a core job competency of security screener at Incheon International Airport, and to verify its effectiveness through empirical analysis to suggest ways to improve the level management system. Methods: In this study, the effectiveness of the research model was analyzed using T-test tests for effect analysis based on the empirical analysis results derived through the competency evaluation model, the screening rating system. Results: The results of this study are as follows. The average score for regular education before the implementation of the x-ray screening rating system was 94.1 points, but after the implementation of the x-ray screening rating system, the average score for regular education was 95.5 points, an average of 1.4 points increased. In addition, the proportion of those with 95 or more points classified as high scorers also increased significantly from 51.1% to 69.3%. Conclusion: The X-ray screening rating system of security inspectors will systematically manage the level of screening ability, which is a key job competency, and play a strong role in improving competency, while preventing security accidents through early identification and intensive training of level-lowers.

Security operating system applied to MAC(Mandatory Access Control) or to MLS(Multi Level Security) gives both subject and object both Security Level and value of Category, and it restrict access to object from subject. But it violates Security policy of system and could be a circulated course of illegal information. This is correctly IPC(Interprocess Communication)mechanism and Covert Channel. In this thesis, I tried to design and implementation as OS kernel in order not only to give confidence of information circulation in the Security system, but also to defend from Covert Channel by Storage and IPC mechanism used as a circulated course of illegal information. For removing a illegal information flow by IPC mechanism. I applied IPC mechanism to MLS Security policy, and I made Storage Covert Channel analyze system call Spec. and than distinguish Storage Covert Channel. By appling auditing and delaying, I dealt with making low bandwidth.
