The majority of financial and general business organizations have had individual damage from hacking, worms, viruses, cyber attacks, internet fraud, technology and information leaks due to criminal damage. Therefore privacy has become an important issue in the community. This paper examines various elements of the information security management system and discuss about Information Security Management System Models by using the analysis of the financial statue and its level of information security assessment. These analyses were based on the Information Security Management System (ISMS) of Korea Information Security Agency, British's ISO27001, GMITS, ISO/IEC 17799/2005, and COBIT's information security architecture. This model will allow users to manage and secure information safely. Therefore, it is recommended for companies to use the security management plan to improve the companies' financial and information security and to prevent from any risk of exposing the companies' information.

In this paper, we designed the security management system based on IEC 62351-7 in the Smart Grid environment. The scope of IEC 62351-7 focuses on network and system management (NSM) of the information infrastructure as well as end-to-end security through abstract NSM data objects for the power system operational environment. However, it does not exist that security management system based on IEC 62351-7 manages the security of the power system in the Smart Grid environment, because power equipment or SNMP agents providing NSM data do not exist yet. Therefore, we implemented the security management system to manage the information infrastructure as reliably as the power system infrastructure is managed. We expect that this system can perform the security management of IEC 61850 based digital substation and can be a prototype of the security system for the Smart Grid in the future.

This paper considers the design and management of security MIB for EDI system. EDI system has to establish various securety wervices and mechanisms to protect against security threats. Hence, the EDIsystem requires appropriate security management to monitor and control the security obhects for its security services and mechanisms. In this paper, I identify security objects for management of secueity services defined in the EDIsystem, and propose the design of a security MIB and describe the use of SNMPnetwork management protocol in its management.

Recently, as evaluation of information security (IS) management become more diverse and complicated, the contents and procedure of the evidence to prepare for actual assessment are rapidly increasing. As a result, the actual assessment is a burden for both evaluation agencies and institutions receiving assessments. However, most of them reflect the evaluation system used by foreign government agencies, standard organizations, and commercial companies. It is necessary to consider the evaluation system suitable for the domestic environment instead of reflecting the overseas evaluation system as it is. The purpose of this study is as follows. First, we will present the problems of the existing information security assessment system and the improvement direction of the information security assessment system through analysis of existing information security assessment system. Second, it analyzes the technical guidance for information security testing and assessment and the evaluation of information security management in the Special Publication 800-115 'Technical Guide to Information Security Testing and Assessment' of the National Institute of Standards and Technology (NIST). Third, we will build a framework to implement the evidence collection system and present a system implementation method for the '6. Information System Security' of 'information security management actual condition evaluation index'. The implications of the framework development through this study are as follows. It can be expected that the security status of the enterprises will be improved by constructing the evidence collection system that can collect the collected evidence from the existing situation assessment. In addition, it is possible to systematically assess the actual status of information security through the establishment of the evidence collection system and to improve the efficiency of the evaluation. Therefore, the management system for evaluating the actual situation can reduce the work burden and improve the efficiency of evaluation.

Recently, internal information leaks is increasing rapidly by internal employees and authorized outsourcing personnel. In this paper, we propose a method to integrate internal control systems like system access control system and Digital Rights Managements and so on through expansion model of SIEM(Security Information Event Management system). this model performs a analysis step of security event link type and validation process. It develops unit scenarios to react illegal acts for personal information processing system and acts to bypass the internal security system through 5W1H view. It has a feature that derives systematic integration scenarios by integrating unit scenarios. we integrated internal control systems like access control system and Digital Rights Managements and so on through expansion model of Security Information Event Management system to defend leakage of internal information and customer information. We compared existing defense system with the case of the expansion model construction. It shows that expanding SIEM was more effectively.

정보통신시스템에 대한 기술적 보안만으로는 안전한 정보통신시스템 운영을 보장할 수 없다. 따라서, 안전한 정보통신시스템 운영을 위한 정보보안관리시스템(ISMS)에 대한 연구와 표준화가 활발히 전개되고 있다 우리나라는 2005년 "국가사이버안전관리규정"을 제정하고, "국가사이버안전매뉴얼"의 "보안관리 기준"에 의하여 국가 공공기관이 자체적으로 "보안관리수준 평가"를 수행토록 함으로써 체계적인 정보보안관리 활동이 이루어지도록 하고 있다. 본 논문은 관련 표준들과 호주, 미국의 보안관리 체계에 대하여 조사하고, "보안관리수준 평가" 체계를 효율적인 보안관리 측면에서 분석하고, 이를 통하여 "보안관리수준 평가"의 개선방향에 대하여 연구하였다. 기존의 체계에 추가항목(A/C ; Additional Control), 선택적 보안관리 기준(Selective Controls)구성을 도입하고 평가 준비 절차의 개선을 통하여 각 기관에 최적화된 보안관리 기준을 작성할 수 있도록 함으로써, 기관에 적합한 효율적 보안관리의 수행이 가능하고, 급변하는 정보통신 환경에 유연하게 대응할 수 있도록 하였다.

클라우드 컴퓨팅 서비스는 이용자 요구에 실시간으로 유연하게 컴퓨팅 자원을 제공하고 사용량만큼 과금하는 고효율의 차세대 IT 서비스이다. 그러나 이용자는 데이터를 '위탁'하고, 인프라, 플랫폼, 어플리케이션 서비스를 '제공'받는 '위탁/제공'의 서비스 구조와 적용기술, 자원공유, 데이터센터 위치 등으로부터 비롯된 많은 위협에 직면해 있다. 클라우드 서비스 도입의 가장 큰 걸림돌로 작용하는 보안과 신뢰성을 담보하기 위해서는 객관적인 평가 기준이 필요하다. 지금까지 정보보호관리체계는 조직의 보안관리 및 IT 운영의 보안 지표로 활용되어 왔다. 그러나 클라우드 컴퓨팅 서비스는 기존의 조직 내 IT 환경과는 다른 관점의 보안관리와 평가기준이 필요하다. 본 논문에서는 클라우드 특성에 맞는 정보보호관리체계를 설계하기 위하여 클라우드 서비스의 핵심요소를 위협관리영역으로부터 도출하고 기본적인 보안관리가 누락되지 않도록 기존 정보보호관리체계의 모든 통제영역을 포함하고 있다. 또 온라인 셀프환경에 따른 서비스 이용을 지원하고 서비스 계약, 제공자 사업현황을 포함하는 서비스 보안관리를 추가하여 설계한다.

데이터 주도 시대가 형성되면서 경제적 활용가치가 높은 정보의 수집과 분석, 생산과 유통에 관한 안전성 확보를 위한 정보보호 관리의 중요성이 날로 높아지고 있다. 이러한 환경에서 기업은 정보보호 관리체계(ISMS) 인증을 통해 정보보안에 대한 신뢰를 보장받고 있으나 관리체계를 구성하는 세부영역에 대한 수준 평가와 활용은 제한적이다. 이에 반해 보안 성숙도 모델은 기업의 정보보호 수준을 단계적으로 진단할 수 있고 시급히 개선해야 할 영역을 판단할 수 있음은 물론 기업의 특성과 수준에 맞는 목표 설정을 지원하는 도구가 된다. 본 논문에서는 성숙도 모델을 바탕으로 정보보호 분야에 특화되어 개발, 활용되고 있는 보안 성숙도 모델의 사례인 C2M2를 국내 ISMS인증과 비교, 분석하여 정보보호 관리 수준을 점검하기 위한 모형을 벤치마크 하고 ISMS인증의 정보보호대책 세부영역을 구성하는 점검항목 간 우선순위를 도출하여 단계적으로 정보보호 관리수준을 점검하고 구축을 지원할 수 있는 방법을 살펴본다.

The Enterprise Security Management system is a centralized control system based on predefined security policies by organizations. In Korea, there is a Common Criteria security certification according to the strict standards for various features. As the needs of information security product are increasing, the ESM system should be evaluated with quality characteristics. In this paper, we propose evaluation items for functionality and performance of Enterprise Security Management system, and the best practices for evaluation.

The first thing to be prioritized is to set the scope of the management system when establishing an information security management system for systematic and effective information security management. It is important to set the scope for an organization's information security goals due to the scope affects the organization's overall information security activities. If the scope is set incorrectly, it might become impossible to protect important services and therefore, the scope of the management system should be determined in consideration of the core business services of the organization. We propose a core service selection model based on the organization's mission-critical service and high risk service in order to determine the effective information security management system scope in this paper. Core service selection criteria include the type of service, contribution to sales, socio-economic impact, and linkage with other services.
