Study on Complicated Information System Support Platform

摘要

摘要: 保障复杂信息系统(CIS)的安全、互操作、可扩展和可管理非常关键。该文提出安全的CIS体系结构模型以指导CIS的建设或改造。模型把CIS划分为不同层次以降低系统复杂度，采用Web Service技术实现互操作和可扩展，使用密码支撑层、安全防护与可靠性支持层在不同层面保证安全性与可靠性。通过系统管理层与各层交互，实现系统的可管理性。某电子政务试点示范工程案例及其网络统计、网络仿真证明模型不会影响业务系统性能。模型适用于政府、军队、银行等高安全级别的信息系统。适当简化模型中相应层次，模型也可用于相对简单的信息系统。

Abstract: It is crucial to make Complicated Information System (CIS) secure, interoperable, extensible and controllable. This paper presents a secure CIS architecture model to conduct the construction or reconstruction of CIS. It divides CIS into layers to reduce system complexity. Web service is adopted to fulfill interoperability and extensibility. It uses encryption support layer, security protection and reliability support layer to guarantee system security and stability. It uses system management layer to interact with other layers to make CIS administrable. A case study with performance statistic and network simulation show the model can satisfy the need of e-government without interfere with system performance. This model is apt to security-critical environment such as government, military and bank. Been properly simplified, it can be applied to relative simple information system too.
