As rehabilitation psychology analysis system which manages examination information becoming more popular, interoperability, portability and security are becoming major concerns of modern computing. We propose a security model on the type information based access control system for rehabilitation psychology analysis that can enhance both security and availability by separating the functions delivered from object-oriented databases to solve these problems. We apply the access control model specifically to enhancement of security system and also perform a test to verify the security and availability of our model.

현재 미국을 비롯한 선진 국가에서는 ISO 국제 표준인 국제 공통 평가 기준 ISO/IEC 15408(CC v2.1, Common Criteria for Information Technology Security Evaluation))과 공통평가방법론(CEM, Common Methodology for Information Technology Security Evaluation)에 근거하여 IT 제품 및 시스템에 대한 보안성 평가를 하고 있다. 그러나, 현재 CC 및 CEM은 주로 IT 제품의 보안성 평가를 위한 것이며, 실제 IT 환경에서 운용되는 시스템에서 이를 적용해 평가하는데는 많은 어려움이 있다. ISO를 중심으로 각 국에서도 이와 관련해 시스템 평가에 CC를 적용하기 위한 방법론이 검토 중에 있다. 그리고 현재 개발 진행중이거나 시장에 출시된 많은 제품이 여러 단일 제품이 합성된 통합제품 형태로 구성되고 있는 추세이며, 이는 시스템 평가 문제와 더불어 향후 CC 기반의 평가를 활성화시키기 위해 풀어야 할 문제로 제기되고 있다. 본고에서는 각 국에서 추진 중인 시스템 평가 동향을 살펴보고, 현재 ISO/IEC SC27/WG3에 표준화로 제안된 "Security Assessment of Operational System"에 대해 살펴보고자 한다.자 한다.

In the recent years, various researches on the use cases of the cloud computing service have been achieved for its standardization. Notwithstanding, we need more additory effort to refine the operating mechanisms on the cloud computing environment. In this paper, we suggest an operating mechanism on IaaS cloud computing environment that is related to the integrated security management system. By using CloudStack 2.2.4 toolkit, we have built a test-bed for IaaS cloud computing service i.e., SWU-IaaS cloud computing environment. Through operating this hierarchical SWU-IaaS cloud computing environment, we have derived the attributes and the methods of its components. Its scenarios can be described in case of both normal state and abnormal state. At the end, a special scenario has been described when it receives a security event from the integrated security management system.

The vulnerability of privacy in the Identity Management System (IMS) is the most pressing concern of ordinary users. Uncertainty about privacy keeps many users away from utilization of IMS. Therefore, this paper proposes an access-control oriented privacy model for IMS. The proposed model protects privacy using access control techniques with privacy policies in a single circle of trust. We address characteristics of the components of for the proposed model and describe access control procedures. After that, we show the architecture of privacy enforcement and XML-based schema for privacy policies.

지능형 전력망인 AMI(Advanced Metering Infrastructure)에 대한 관심이 높아지고 있다. AMI 시스템은 전력의 제공자와 소비자가 양방향 통신을 함으로써 전력의 효율적인 관리를 위한 것이지만 기존의 전력망에 통신망인 IT의 결합으로 인한 보안 문제에 대한 대응방안이 필요하다. 본 논문에서는 한전 KDN(주)가 규정하여 추진하고 있는 AMI 시스템의 문제점을 분석하고, 한전의 규정상에서 적용 가능한 대칭키 기반의 보안으로 안전한 AMI 시스템의 통신망 구조를 제시하여 암호화 및 메시지인증을 통해 기밀성, 무결성, 가용성 등의 보안 요건을 만족시킬 수 있는 통합적인 관리를 제안한다.

Current security efforts provided in such as firewall or IDS (intrusion detection system) of the network level suffer from many vulnerabilities in internal computing servers. Thus the necessity of secure OS is especially crucial in today's computing environment. This paper identifies secure OS requirements, analyzes tile research trends for secure Linux in terms of security kernel, and provides the descriptions of the multi-level security(MLS) Linux kernel which we have implemented. This security kernel-based Linux meets the minimum requirements for TCSEC Bl class as well providing anti-hacking, real-time audit trailing, restricting of root privileges, and enterprise suity management functions.

Cloud service provider has to protect client's information securely since all the resources are offered by the service provider, and a large number of users share the resources. In this paper, a NoSQL-based anomaly detection system is proposed in order to enhance the security of mobile cloud services. The existing integrated security management system that uses a relational database can not be used for real-time processing of data since security log from a variety of security equipment and data from cloud node have different data format with unstructured features. The proposed system can resolve the emerging security problem because it provides real time processing and scalability in distributed processing environment.

학술정보 통합관리시스템 OCEAN(Online Collaborator for society & Association Network of KISTI)은 학회정보화지원사업의 일환으로 학술정보를 통합관리하기 위해 2007년부터 사용된 통합관리 시스템이다. 구 OCEAN은 Struts2 프레임워크 기반으로 설계되어, 노후화된 프레임워크는 끊임없는 유지보수에도 급변하는 정보기술 환경에 낙후되었고, 보안적 측면 및 신규 기능 구현에 어려움이 있어 2차년도(2015~2016)에 걸친 시스템 재정비를 통해 최신 프레임워크를 적용하여 신규 시스템 설계하고 구축하였다.
