- Firstly , in this paper , we review the histories of xml and xml database , and all kinds of data models used widely now . then we review traditional access control policies and policies specially used on xml , and present a new expression method of access set on xml based on child tree of w3c data model . and we bring rbac model into xml database and present a new xml access model x - rbac . because the usage of data in databases has high frequency , we present an ids model based on access set density to logging the potential security threats . and then we introduce the design and implementation of a prototype of our native xml database nhx and its access control system . finally , we draw a conclusion for this paper and the future work
本文首先回顾了xml及xml数据库的历史,并总结了目前广泛使用的xml数据模型,在分析了各种传统数据库访问控制策略,以及xml的专有访问控制策略的优缺点后,基于w3c的xml数据模型,提出了一种基于子树的具有高弹性的便于实现的的访问区域表示法,并将rbac模型引入进来,提出了一种适用于xml数据库的访问控制模型x - rbac ,同时为了区分xml数据库访问中的合法访问和合理访问,我们根据数据库访问具有频繁性这一特征,提出了一种基于区域访问密度的入侵检测模型( ids ) ,以对隐藏在正常访问中的潜在安全威胁进行报警和日志。 - For example , when tivoli or other application management software running in your operational environment determines that there s a problem with a piece of production software , wouldn t it be helpful if the change request included the information " . this problem appears in models x , y and z , and it was added in this build , in this iteration , on this date , etc . "
比如，当tivoli （或者运行在你的操作系统上的其他应用管理系统）测定在产品软件的某一部分存在问题时，如果变更请求中包含信息的话，那不是非常有用的吗“ . . .这个问题出现在模型x 、 y和z中，他们是在这个版本，这个迭代和这个日期等等中被添加的？ ”
