| Summary: | 碩士 === 國立政治大學 === 資訊管理研究所 === 99 === To develop Enterprise Portal System, most enterprises always meet the problem of satisfying numerous security standards and dealing with complicated programming languages. It still lacks an integrated security solution which could provide enterprises an easy way to complete this task. Therefore, this technical problem leads to an entrance barrier and significant corresponding cost to enterprises when deploying their portal. Service-Oriented Architecture is a promising framework to improve the situation. Service-Oriented Architecture framework is distributed, combinable, standardized which and develop the security mechanisms security mechanisms in Service-Oriented Architecture environment. Considering the advantage of Service-Oriented Architecture, this study explores the possibility of building Security Services for Service-Oriented Enterprise Portal. This study analyzes Service-Oriented Architecture security and security services. In addition, the authors propose a Service-Oriented security service prototype architecture for enterprise portal to meet its security requirements. This architecture can integrate service-oriented security services into enterprise portal applications and improve security level. Accordingly, it could develop a highly reliable enterprise portal and create a better competitiveness. The work done by this study includes (1) analyzes the security requirements in a service-oriented enterprise portal, (2) proposes a new framework for enterprise portal service-oriented security services, and (3) demonstrate this framework can support complete security functions for enterprise portal, be flexibility to increase security functions for demands in the future and continue to strengthen the enterprise portal security. By considering this new framework, the design a Enterprise Portal System could be more convenient and secure and it will benefit the development of enterprise in the future.
