For social demand and technological development, systematic private information management and security guidance have been enhanced; however, the issue of leakage and invasion of private information is shown in many ways. In the management of such private information, the issue of how to protect such information is one of the sensitive key elements. As a criterion to decide the management policy of each property information consisting of private information, this article suggests Dynamic-Security-Level-Measurement for property information. DSLM adopts the variable characteristics of property information as the element of measurement. By applying this method, it is possible to provide information management functions to cope with the changes of each property information security level of an individual actively. It is expected that this will improve the security of previous information management methods even more and also contribute to the improvement of security in integrated systems such as the integrated ID management system and electronic wallet.

Union file system is a technology that can be used as a single file system by integrating various files and directories. It has the advantage of maintaining the source file/directory used for integration, so it is used in many applications like container platform. When using the union file system, the user accesses the write-able layer, to which the security technology provided by the operating system can be applied. However, there is a disadvantage in that it is difficult to apply a separate security technology to the source file and directory used to create the union file system. In this study, we intend to propose an access control mechanism to deny security threats to source file/directory that may occur when using the union file system. In order to verify the effectiveness of the access control mechanism, it was confirmed that the access control mechanism proposed in this study can protect the source file/directory while maintaining the advantages of the union file system.

Information protection system (Information protection system)-based IT environment built popularity in public agencies and businesses take advantage of the resources for the integration of the information system one essential environment began to recognize, cloud systems (Cloud System), cloud security (Cloud Security), big data (Big Data), big data security (Big Data Security), industrial security (Security Industry), as well as the issue. Due to the influence of these information protection system (Information protection system) in response to my external security threats based on the analysis plan. In this paper, data protection systems (Information protection system), resulting in the introduction, there are a number of security threats and particularly industrial security aspects and internal and external security threats in response by lighting about aspects of the plan is based on knowledge.

With the Internet winning a huge popularity, there rise urgent problems which are related to Network Security Managements such as Protecting Network and Communication from un-authorized user. Accordingly, Using Security equipments have been common lately such as Intrusion Detection Systems, Firewalls and VPNs. Those systems. however, operate in individual system which are independent to me another. Their usage are so limited according to their vendors that they can not provide a corporate Security Solution. In this paper, we present a Hierarchical Security Management Model which can be applicable to a Network Security Policies consistently. We also propose a Policy Negotiation Mechanism and a Prototype which help us to manage Security Policies and Negotiations easier. The results of this research also can be one of the useful guides to developing a Security Policy Server or Security Techniques which can be useful in different environments. This study also shows that it is also possible to improve a Security Characteristics as a whole network and also to support Policy Associations among hosts using our mechanisms.

자율운항선박을 IMO 자율화등급 3단계 이상으로 운용하기 위해서는 내·외부 통신시스템의 사이버보안뿐만 아니라 실시간으로 데이터를 교환하는 데이터 및 시스템 사이버안전에 대한 고려가 필수적으로 요구된다. 본 연구에서는 자율운항선박 사이버안전체계 구축방안에 대해서 살펴본다. 자율운항선박 사이버안전체계 구축을 위해서는 선박 내 사이버위협을 실시간으로 탐지하고 영향을 모니터링하는 통합 보안 시스템 구축이 필요하며, 선박 사이버안전 설계 타당성을 검증하는 사이버리스크평가 기술, 사이버안전체계를 검증하기 위한 CVE(Common Vulnerabilities Enumeration)기반 취약성 진단 및 침투테스트 기술, V-Model을 활용한 통합 소프트웨어 품질인증 기술, ISO 25024 기반 데이터 무결성 검증 기술 적용이 필요하다.
