Recently, the breakdown of online banking servers and the leakage of customer information give rise to much concern about the security of information systems in financial and banking companies in Korea. The enforcement of security for information system becomes much more important issue than earlier. However, the security reinforcement of information system is restricted by a budget. In addition, the activities' cost to secure information system from threatening are under uncertain circumstances and should be established by a human decision maker who is basically uncertain and vague. Thus, making the budget for information system is exposed to any extent of the risk for these reasons. First, we introduce brief fuzzy set theory and fuzzy AHP (Analytic Hierarchy Process) methodology. Then, the cost elements that comprise yearly budget are presented and the priorities among the cost elements are calculated by fuzzy AHP. The cost elements that are exposed to risk are evaluated from the both perspectives of the risk impact and risk occurrence possibility which are expressed as linguistic terms. To get information on the risk profiles-pessimistic, most likely, and optimistic-for each cost element, the evaluation is accomplished and the result is presented. At last, the budget ranges-minimum, mode, maximum-for each cost element are estimated with the consideration of the risk profiles.

정보보호를 효율적이고 효과적으로 실천하는 방법으로 정보자산을 기준으로 위험관리를 수행하는 GMITS(ISO 13335)과 정보보호 관리체계 수립을 위한 ISMS(ISO 27001), 정보보호 능력성숙도 모델을 제시하는 SSE-CMM 등의 국제 표준이 존재한다. 그러나 각 표준은 위험관리를 위한 절차를 제시하거나 관리체계 수립방안, 그리고 능력성숙 수준을 제시하는 등 관리, 기술, 운영의 종합적인 보안방안을 제시하지는 못하고 있다. 또한 현 보안문제를 최고 관리자 수준에서 판단할 수 있는 종합적인 방안을 제시하지 못하고 있다. 본 논문에서는 정보시스템 보안평가를 통해 보안 기술, 관리, 운영측면의 문제점을 종합하여 위험관리가 가능하도록 하는 방안을 제안하고, 또한 제안한 위험관리를 통해 도출된 문제점을 최고관리자 수준에서 직관적으로 판단 할 수 있는 방안을 제시하여 정보보호 예산과 연계할 수 있는 방법을 제안한다.

Disaster and safety budget can be characterized as a large-scale public asset on which the government has a significant role. It is of a crucial importance to properly allocate the limited national budget to various areas as necessary. Higher investment efficiency of the budget related to disaster and safety management requires distribution criteria based on relevance and efficiency. Currently, the budget related to disaster and safety management is orchestrated through the prior consultation system. However, there is still no clear framework for reviewing the investment direction and setting the priority investment areas by prior consultation. This study analyzes the status and characteristics of disaster and safety management projects by damage type and proposes a structured system for prioritization. This framework can be useful in selecting the areas that need priority investments by damage type of disaster and safety management projects, thereby contributing to improving investment efficiency.

The security risk management used by some service providers is not appropriate for effective security enhancement. The reason is that the security risk management methods did not take into account the opinions of security experts, types of service, and security vulnerability-based risk assessment. Moreover, the security risk assessment method, which has a great influence on the risk treatment method in an information security risk assessment model, should be security risk assessment for fine-grained risk assessment, considering security vulnerability rather than security threat. Therefore, we proposed an improved information security risk management model and methods that consider vulnerability-based risk assessment and mitigation to enhance security controls considering limited security budget. Moreover, we can evaluate the security cost allocation strategies based on security vulnerability measurement that consider the security weight.

The purpose of this study is to examine the operational performances by the investment level of information security in companies. The theoretical background summarized the meaning of information security, management information security, and network security. The research process was carried out in four stages. As a result of the analysis, the level of information security was classified into four groups, and the difference in operational performance was confirmed. According to the categorical regression analysis of the three dependent variables, independent variables such as network threats, non-network threats, executive information security awareness, industry, organizational size, and information security education all affected information security regulations, in-house information security checks, and information security budget investments. The theoretical implications of this study have contributed to updating the latest information security theory. Practical implications are that rational investments should be made on the level of information security of companies.

Although more than 99% of all Korean companies are small and medium-sized enterprises (SMEs), which accounts for a large part of the national economy, they are having difficulties in securing information protection capabilities due to problems such as budget and manpower. On the other hand, as 97% of cyber incidents are concentrated in SMEs, it is urgent to strengthen the information protection management and response capabilities of SMEs. Although the government is promoting company-wide information security consulting for SMEs, the need for supplementing it's procedures and consulting items is being raised. Based on the results of information security consulting supported by the government in 2020, this study attempted to derive improvement plans by interviewing SME workers, information security consultants, and system operators. Through the research results, it is expected to create a basis for SMEs to autonomously check the information security management system and contribute to the reference of related policies.

Federal Information Security Management Act emphasizes the importance of information security to the economic and national security interests of the United States. This paper provides a brief review on FISMA which is a United States federal law enacted in 2002 as Title III of the E-Government Act of 2002, and predicts the possible problems which might be caused from domestic introduction of FISMA. The domestic introduction of FISMA could improve the average level of information security of government agencies. Whereas, the government agencies and the government officials might face with many problems such as the increased government budget, lack of social awareness and security professionals, and the effectiveness of penalty on non-compliance.
