SoftOS中系统安全视图的设计与实现

安全信息的复杂性和多样性使得用户很难对系统的安全状况有直观全面的了解，更不用说时异常事件的及时响应和处理了。在构建安全增强型操作系统SoftOS的过程中，我们通过研究操作系统中各种主客体，包括用户、进程及其它各种系统资源之间的关系的表达，资源消耗情况同系统安全之间的联系等，设计与实现了系统安全视图Sec-View，以达到能够提供集成全面的安全相关信息并予以分析，辅助用户直观地了解系统的安全状况和做出正确处理。本文即对这一设计和实现予以阐述。

Design and Implementation on System Security View in SoftOS

The complexity and diversity of the security make it difficult for users to get an intuitionistic and full-scale comprehension of security conditions of the system,let alone timely response and disposal with abnormal events.In the process of building SoftOS,a type of security strengthened OS,by means of research on the relationships between various subjects and objects,as well as the resource consumption and system security,we design and implement the System Security View,i.e,SecView,for the purpose of providing and analysing integrated and comprehensive security related information so as to assist users in knowing the security status of the system fully and conducting proper disposals.
