开放系统安全性

在开发系统环境中，安全性是极为重要的一个方面。只有保证了安全性，才能体现出开放系的优越性，本文对ＯＳＩ安全体系进行了分析，指出该结构主要涉及的是通信安全性，通过分析开发系统的特点和安全需求，探明了开放系统安全性应包括三个方面：通信安全性、端系统安全性和管理安全性。探讨了开放系统安全性的设计和实现方案。

OPEN SYSTEM SECURITY

Security is one of the most important components for open system environments. Advantages of the open system will become hollow ones if its security can not be perfectly ensured. The analysis of OSI security architecture shows that it only involves in communication security. From the features and requirements of open system, it is deduced that open system security contains three aspects: communication security, end-sysytem security and management security. Design and implementation of the open system security are discussed.
