보안 제품의 개발이 많아지면서 각 제품에 대한 통합의 필요성이 대두되고 있다. 예를 들어, 침입탐지 시스템에서 침입을 시도하는 노드를 판별한 경우, 실제 그 노드로부터의 접속을 차단할 수 있는 기능을 방화벽 시스템에서 제공하고 있기 때문에, 방화벽 시스템으로 접속 차단 명령을 보낼 수 있는 기능이 제공된다면 보다 자연스럽게 통합 관리가 이루어 질 수 있을 것이다. 그러나, 현재 보안 시장은 많은 종류의 보안 제품이 존재하기 때문에 이러한 통합이 쉽게 이루어지지는 않고 있다. 정보보호에 대한 관심이 높아지면서 많은 기업이 각종 보안시스템을 도입하고 있지만, 각 보안 시스템의 개별 관리에 중점을 두고 있어 이기종 보안 시스템간의 연동에 기반한 통합 관리 차원의 필요성이 증가된다. 따라서, 국내외의 많은 보안 업체들이 이기종 보안 제품의 연동을 위한 방안들을 제시하고 있으며, IETF(Internet Engineering Task Force)를 중심으로 표준화 작업이 진행되고 있다. 본 논문에서는 국내외 각 보안 업체 혹은 보안 업체간 컨소시엄 형태로 제안된 이기종 보안 솔루션 연동 방식 및 공개 API(Application Programming Interface) 형식들을 분석하고, 표준화 동향에 대해 살펴본다.

Enterprise security management system proposed to properly manage heterogeneous security products is the security management infrastructure designed to avoid needless duplications of management tasks and inter-operate those security products effectively. In this paper, we propose the model of generalized security policies. It is designed to help security management build invulnerable security policies that can unify various existing management infrastructures of security policies. Its goal is not only to improve security strength and increase the management efficiency and convenience but also to make it possible to include different security management infrastructures while building security policies. In the generalization process of security policies. we first diagnose the security status of monitored networks by analyzing security goals, requirements, and security-related information that security agents collect. Next, we decide the security mechanisms and objects for security policies, and then evaluate the properness of them on the basis of security goals, requirements and a policy list. With the generalization process, it is possible to integrate heterogeneous security policies and guarantee the integrity of them by avoiding conflicts or duplications among security policies. And further, it provides convenience to manage many security products existing in large networks.

Recently, Networks are required to adopt the security system and security consulting because of security threats and vulnerabilities of systems. Enterprise Security Management (ESM) is a system which establishes the security zone composed of security systems and Firewalls and applies the security policy to each security system. A relevant ESM is based on the effective policy and the proper security system. Particularly, multiple firewalls in ESM are concerned with the security policy about each traffic. In this paper, we describe the problems that can be occurred when we select the firewalls to apply security policy of access control in ESM composed of multiple firewalls and propose the FALCON algorithm, which is able to select the firewalis to apply the policy. We expect that FALCON algorithm offers stability, scalability and compactness for selecting firewall set.

Security infrastructure of Educational Network responds to threats by collecting and analyzing security events from various information protection system based on the integrated management system. Even if this system provides useful and detailed information to the administrator, there are some problems that this system does not provide effective response process and management systems for various threatening situations and the simultaneous threat processes. To solve this problem, we propose and develop security agents that enable the administrator to effectively manage integrated security for Educational Network. The proposed solution provides the administrator with efficient management techniques and process scheduling for various security events so that the administrator can response promptly to problems with the initial threat to Educational Network.

Recently It's difficult to deal with about variety of attack. And Simple Security management have a problem. It is that they don't develop system measuring their system envoirment and have efficient attack detector, countermeasure organization about large network. Therefore, need model about enterprise management of various security system and intrusion detection of each systems and response. In this paper, improve PBNM structure that manage wide network resources and presented suitable model in intrusion detection and response of security system. Also, designed policy-based enterprise security management system for effective intrusion detection and response by applying presented model to enterprise security management system.

This thesis proposes how data security has changed since the emergence of 'Big Data' in 2012 and the type of Integrated Security Management System that needs to be built against security threats, based on an analysis of Big Data. Much research has been conducted in Big Data. I need to think about what an Integrated Security Management System requires in order to safeguard against security threats such as APT. I would like to draw a comparison between the current Integrated Security Management System and one that is based on Big Data, including its limitations and improvements, so that I can suggest a much improved version of Integrated Security Management System.

유비쿼터스 사회가 도래함에 따라 유비쿼터스 기술을 도시에 적용한 u-City가 개발되고 있다. u-City는 다양한 정보화 기기들이 존재하며 정보화 기기 사이를 연결하는 다양한 네트워크 기술이 상존한다. u-City의 핵심 요소인 u-City 통합운영센터는 u-City 내의 모든 서비스를 처리하도록 설계되었으며, 도시를 통제 관리하는 중요한 업무를 수행한다. 이 중에서 보안관리 업무는 시스템에서 수집, 가공, 산출하는 데이터 및 정보의 보안유지를 위해 중요한 부분이다. 따라서 본 논문에서는 u-City 통합운영센터의 보안유지를 위한 기술적, 물리적, 관리적인 측면에서 보안관리 대책을 제시하였다.

As new information technology emerges, companies are introducing an Enterprise Security Management system to cope with new security threats, reducing redundant investments and waste of resources and counteracting security threats. Therefore, it is necessary to construct a security evaluation metric based on related standards to demonstrate that the Enterprise Security Management(ESM) System meets security. Therefore, in order to construct a metric for evaluating the security of the ESM, this study analyzed the security quality related requirements of the ESM and constructed a metric for measuring the degree of satisfaction. This metric provides synergies through the unification of security assessments that comply with ISO/IEC 15408 and ISO/IEC 25000 standards. It is expected that the evaluation model of the security quality level of ESM will be established and the evaluation method of ESM will be standardized in the future.

갈수록 심각해져가는 보안위협 속에 많은 기관들은 다양한 정보보호시스템을 구축하고, 이를 통합하는 통합보안관리시스템을 운영하고 있다. 이러한 통합보안관리시스템은 이기종간 보안로그를 상호연관분석 할 수 있는 기능을 다양한 방법을 통해 제공하고 있다. 이러한 다양한 상호연관분석 방법 중 다단계 상호연관분석 방법을 이용한 통합보안관리시스템에서 내부자원이 악성코드에 악용되는 걸 사전에 탐지할 수 있는 상호연관분석 정책을 제안한다.
