APT cyber attacks have been a problem for over a past decade, but still remain a challenge today as attackers use more sophisticated techniques and the number of objects to be protected increases. 'Cyberattack Tracing System' allows analysts to find undetected attack codes that penetrated and hid in enterprises, and to investigate their lateral movement propagation activities. The enterprise is characterized by multiple networks and mass hosts (PCs/servers). This paper presents a data processing procedure that collects event data, generates a temporally and spatially extended provenance graph and cyberattack tracing paths. In each data process procedure phases, system design considerations are suggested. With reflecting the data processing procedure and the characteristics of enterprise environment, an operational architecture for CyberAttack Tracing System is presented. The operational architecture will be lead to the detailed design of the system.

This study is about the effect of original brand on the evaluation of extended brand in the policy of an enterprise's extending its brand. More specifically, this study investigated to see whether the customers' attitude toward original brand has effect on an extended brand and the width and similarity extent of the brand extension affect a brand which is not similar when another brand is extended. The summary of the demonstrative analysis results are as follows: 1. If the attitude toward original brand becomes more positive, the evaluation of the extended brand will become more positive as well. 2. If the attitude toward original brand becomes more positive, the width of a brand extension will become wider. 3. If customers' attitude toward a original brand is positive, their attitude toward an extended brand will be positive as well although the extended brand is not similar to the original brand. This study proved it is possible for brands to be extended from a original brand under the influence of the original brand even though they are weak in their similarity to their original brand unlike the existing theory which was skeptical about the extension of a brand which is low in its similarity to its original brand and that the success of the extension of a brand does not depend upon its similarity to its original brand.

The Virtual Local Area Network (VLAN) has been used for a long time in campus and enterprise networks as the most popular network virtualization solution. Due to the benefits and advantages achieved by using VLAN, network operators and administrators have been using it for constructing their networks up until now and have even extended it to manage the networking in a cloud computing system. However, their configuration is a complex, tedious, time-consuming, and error-prone process. Since Software Defined Networking (SDN) features the centralized network management and network programmability, it is a promising solution for handling the aforementioned challenges in VLAN management. In this paper, we first introduce a new architecture for campus and enterprise networks by leveraging SDN and OpenFlow. Next, we have designed and implemented an application for easily managing and flexibly troubleshooting the VLANs in this architecture. This application supports both static VLAN and dynamic VLAN configurations. In addition, we discuss the hybrid-mode operation where the packet processing is involved by both the OpenFlow control plane and the traditional control plane. By deploying a real test-bed prototype, we illustrate how our system works and then evaluate the network latency in dynamic VLAN operation.

Networked enterprise (NE) is an organization of independent companies that collaborate with each other temporary or permanently for accomplishing common goals. The USA and EU have been developing principal concepts, techniques, and solutions to enhance the competitiveness of traditional industries including small-and-medium enterprises (SMEs). In Korea, however, implementation as well as R&D of NE is very few, which we believe comes from lack of understanding on Its meaning and lack of effective information systems for it. This paper is to suggest an Enterprise Architecture (EA) framework or reference model of NE and an Information Technology Architecture (ITA) of NE. The EA framework will help stakeholder of NE (e,g., policy makers, members of NE, IT solution providers, and researchers) understand structural and behavioral characteristics of NE. The ITA will be used as a guideline of developing information systems for NE that is essential for spreading networked business models, The focus of this paper is not on logical-level design but on conceptual-level modeling of NE. As verification of the suggested framework and architecture is still required, so we'll apply them to various manifestations of NE, e.g., dynamic supply chain, vertical integration of extended enterprises, and P2P-style virtual enterprises.

인터넷과 웹이 활성화됨으로써 사용자는 문서, 디렉토리, 데이터베이스, 웹 페이지 등과 같은 자원들을 액세스하는 것이 훨씬 더 쉬워졌다. 그러나 이로 인하여 네트워크의 인증, 자원들을 액세스하기 위한 권한의 허가, 데이터의 정책과 보안 그리고 보안 시스템의 무결성과 같은 중대한 보안 문제들이 생기게 되었다. 본 논문에서는 기업 환경의 접근제어를 위하여 시간(기간과 주기)에 따른 제약으로 자원의 사용을 제한할 수 있는 GTRBAC(Generalized Temporal Role Based Access Control) 모델에 부역할(sub-role) 개념과 PBDM(Permission Based Delegation Model) 개념을 적용한 확장된 GTRBAC 위임(Ex-GTRBAC Delegation)모델을 제안한다. 제안 모델은 부역할을 사용하여 하위 역할에 할당된 권한을 상위 역할에 할당된 사용자가 모두 상속하여 실행할 수 없도록 하여 권한의 남용을 방지하여 최소권한의 원칙을 지킬 수 있도록 하고, 기업 환경에서 빈번히 발생하는 권한의 위임에 대해서 사용자 대 사용자 위임, 역할 대 역할 위임, 다단계 위임, 다중 위임과 같은 기능을 제공하여 기업 환경의 특성에 따라 다양하고 정교한 접근제어 정책을 적용할 수 있도록 한다.

This is an era in which companies should realize sustainable management through business models that propose social values beyond financial benefits and solve social problems. Accordingly, the role of corporate designers should be extended to social value propositions and materializations, including corporate profit-seeking. Among the members and organizations of the company, design organization and designers have strengths in terms of humanities and creativity compared to other organizations and members. We should actively seek opportunities for corporate designers to find the context of connecting businesses and society on their own, actively seek opportunities to integrate them with corporate design, expand the role of corporate designers through creative ideas, and actively pursue sustainable and wide social career development that encompasses both inside and outside of the company. To this end, we suggested three transitions of thougths to change the perception of fixed and straight-line forms of enterprise organization, enterprise design approach and product development process so far to present useful insights through case studies, how enterprise designers can accommodate social impact through new communication and access.

The focus of enterprise collaboration of supply chain management, has changed from integrating and exchanging business information to integrating and managing business processes between business partners. However, the collaboration is difficult due to the inherent complexity such as diverse business processes and dynamic business environments. To settle these problems, a reference model based enterprise architecture framework for the collaboration of supply chains is proposed in this paper. The supply chain collaboration framework is composed of three reference models capturing the different views of supply chain collaboration: supply process reference model, service component reference model, and technology and standard reference model. As the framework adapts the OMG's metadata architecture, the processes in the supply chain can be extended and integrated with other value chains, such as design chains, when it is necessary. Using the proposed framework, business managers can rapidly integrate and manage their business processes with their suppliers and customers.
