기업 및 공공기관의 클라우드 서비스 도입이 확산되면서 업무 시스템에 대한 보안 요구사항이 변화하고 있다. 기존에는 보호해야 할 정보자산이 물리적으로 외부와 분리된 내부 공간에 집중되었다면 클라우드 환경에서는 자산의 분포 범위가 넓어지면서 내부와 외부의 경계가 모호해진다. 따라서 경계 기반의 전통적인 보안 방식은 클라우드 기반 업무환경에 적합하지 않으며 정보 서비스를 이용하는 전 주기에서 암묵적인 신뢰를 배제하고 지속적으로 검증을 수행하는 제로 트러스트 기반의 업무 시스템 운영이 필요하다. 본 논문에서는 스토리지 클라우드 서비스인 아마존 웹 서비스 S3(Simple Storage Service)에 대하여 제로 트러스트 모델을 설계하고, 직접 서비스를 운영하며 제안된 제로 트러스트 모델의 안전성을 검증한다. 제로 트러스트 모델은 스토리지에 접근하는 사용자에 대한 인증 및 식별 기술, 스토리지 암호화 기술, 암호화 키 관리 기술을 활용하여 설계하였으며 제로 트러스트 기술 적용 시, 스토리지 보안성이 향상되는 것을 실제 서비스 운영을 통한 실험을 통해 확인하였다.

The universal cloud computing environment, the increase of mobile devices, and the emergence of various web-based services require large amounts of storage space. With the widespread use of Web-based storage services, such as Google Drive, Naver Ndrive, Daum Cloud, there is a need for more storage space. Therefore, storage areas can be provided according to the needs of users of virtualized storage resources through a network, and a large, easy to extend, and royalty in a specific geographical location, cloud storage may be the limelight. In this paper, find out about the features of open source software technology, Hadoop, Swift, GlusterFS for Cloud Storage infrastructure.

With the help of information technology, the web 2.0 gives people the environment where they share informations and a means of expressing ideas. The power of web affects interactive storytelling for Alternate Reality Game (ARG). There are less theoretical approaches and practices about ARG in Korea and to understand ARG into a deeper sense shall contribute to the development of domestic culture and its contents. In order to realize this, first we will explore the general idea about ARG. Second, know its elements in Interactive storytelling and finally, analyze the examples.

IT 산업의 발달과 함께, 정보의 양은 기하급수적으로 증가하고 있고, 최소의 비용으로 정보의 가치를 최대로 창출하기 위해 서버와 스토리지 간에 대용량 데이터를 고속으로 전송할 수 있는 네트워크인 SAN(Storage Area Networks)의 급속한 발전을 하게 되었다. 이에 따라 네트워크로 연결된 자동화 스토리지 인프라는 물론 포괄적인 서비스 및 솔루션이 결합된 새로운 정보 관리 전략인 ILM(Information Lifecycle Management)이 대두되기 시작했다. 본 논문은 SAN 을 효율적으로 관리할 수 있고, ILM 을 위한 웹 기반 솔루션인 SANCruiser 시스템을 제안한다.

HTML5 has developed not to have browser dependancy considering interoperability as same as maintaining compatability with lower versions of HTML. HTML5, the newest web standardization is on going of being structured. Along with the smart phone boom, HTML5 is spotlighted because it can be applied to cross platforms in mobile web environments. Specially the local Storage that has been listed in new features in HTML5 supports offline function for web application that enables web application to be run even when the mobile is not connected to 3G or wifi. With Local storage, development of server-independent web application can be possible. However Local storage stores plaintext data in it without applying any security measure and this makes the plaintext data dangerous to security threats that are already exist in other client side storages like Cookie. In the paper we propose secure Local storage methods to offer a safe way to store and retrieve data in Local storage guaranteeing its performance. Suggested functions in this paper follow localStorage standard API and use a module that provide cryptographic function. We also prove the efficiency of suggested secure Local storage based on its performance evaluation with implementation.

Web-based Promotion of companies have several advantages: They can publicize the brand image in various ways; they enable consumers to learn the information of products in the round with interests; they can stretch out their marketing targets to the whole world. In order to make an effective delivery of their information in such promotion websites, interaction with their consumers is an important factor, for which understanding Interactive Storytelling is essential. The purpose of this thesis is to study Interactive Storytelling which enables us to have effective interaction with consumers in making promotion websites of companies. For this, this thesis analyzes examples of Interact Storytelling focused on it have story promotion websites on the basis of the five steps for internet marketing promotions: attraction of visitors, attraction of interests and participations, acquisition of the information of customers, grasp of the needs of customers, and an offer of values classified by customers.

This paper presents an optimized adoption of NVM for the storage system considering application characteristics. To do so, we first characterize the storage access patterns for different application types, and make two prominent observations that can be exploited in allocating NVM storage efficiently. The first observation is that a bulk of I/O does not happen on a single storage partition, but it is varied significantly for different application categories. Our second observation is that there exists a large proportion of single accessing in storage data. Based on these observations, we show that maximizing the storage performance with NVM is not obtained by fixing it as a specific storage partition but by allocating it adaptively for different applications. Specifically, for graph, database, and web applications, using NVM as a swap, a journal, and a file system partitions, respectively, performs well.

Due to the development of new digital technologies in recent years, consumers play different roles with compared to the past. Though they used to consume various existing contents, nowadays they have opportunities to use in user-friendly environment which can make them create and share their own contents. Under this circumstance, the digital storytelling has become a big issue in large area, and the web-based contents have been produced with diverse contests. In fact, the digital storytelling means a kind of storytelling method which is made by digital technologies and has been created under various circumstances. However, many researches concern that the digital storytelling is just applied for moving from analog to digital in terms of a tool, but in the reality it is far from the web 2.0 with collective intelligence. Therefore, in this paper, we propose a web-based collaborative digital storytelling platform that analysis user's action processes and components applying collective intelligence.

As the development of IT technology and Web services have changed recently, education environment combined with high-tech digital content is becoming a new trend with the demands of educational consumers. In Korea, however, there is no systematic discussion on the issue, and there is not enough evidence to verify the effectiveness of the research. Therefore, we will systematically analyze the educational effects of Digital Storytelling to create an educational environment that meets the new horizon of intelligent web and personalized service provision in the Web3.0 era, In this study, 12 domestic experimental studies that verify the educational effects of digital storytelling were systematically analyzed, compared with overseas cases, and proposed development plans in the Web3.0 era.
