Recently, with the enlargement of cloud computing, virtual desktop infrastructure(VDI) can be an alternative of the existing personal computer based information environment. For the case of partially introduced VDI coexisting with personal computer environment, we suggest a virtual folder based approach to control the overall digital contents within an organization with a case of implementation. Although a centralizing device was used for storage and sharing of organization's digital contents, it was not easy to accomplish centralizing digital contents completely. It is tried to prevent users from utilizing their own storage in their personal computers or virtual machines and to use virtual folder which transfer and store digital contents to and in EDMS. The virtual folder system of this paper looks like a real folder in a personal computer, but it is another virtual device for outer storage devices including EDMS. It can be an alternative and reference of digital contents control for future applications of cloud computing.

EDMS systems have been a main alternative for enterprise content management (ECM), which provide valuable functions for the effective control and management of organization-level digital contents. However, it has not been effective frequently for the purpose of integrative control of overall contents in an organization. One of reasons for this problem is that individuals usually create and store files with their own personal computers and do not move them to the central storage and control device, EDMS. Many occasions show that this situation can cause undesirable results for better management of enterprise contents. This paper introduced an approach of virtual folder which can directly connect individual computers and EDMS storage device without users' inconvenience. Adding the capacity of restricting usage of individual computer, users unavoidably and conveniently store and retrieve digital contents using EDMS server system. Several modules and implementing architecture for the virtual folder system are shown and the results of utilizing the system are explained with a case of application.

독특하게도 WannaCryptor는 사용자 데이터를 암호화하고 이를 복구하려면 돈을 요구하는 랜섬웨어임에도 불구하고 Windows 운영체제의 공유 폴더 취약점을 이용하여 스스로 확산하는 인터넷 웜과 같은 특징을 가진다. 본 논문에서는 기존 랜섬웨어와는 차별화되는 WannaCryptor의 확산 방식에 초점을 맞추어 확산을 분석하고 예측한다. 이를 위하여 가상 환경에서 동작 실험을 진행하였고, 확산 예측 모델링을 통하여 다양한 환경에서 WannaCryptor 확산의 양상을 분석하였다.
