从安全性的角度来看，必须跨所有功能(比如工作流、关系和层次结构管理)实现属性级的特权授权粒度。
From a security perspective, attribute-level granularity of authorization privileges across all functions such as workflow, relationship and hierarchy management must be available for implementation.
以相似方式作为数据库特权授予和撤消数据库级权限（比如 DBADM、CONNECT、CREATETAB 和LOAD）。
The database level authorities, such as DBADM, CONNECT, CREATETAB, and LOAD, are granted and revoked in a similar way as database privileges.
探测器在操作系统内核级上监视所有数据库事务，包括特权用户的事务，而不依赖于数据库审计日志。
The probes monitor all database transactions, including those of privileged users, at the operating system kernel level without relying on database audit logs.
系统内核所使用的内存空间通过特权码（privileged code，2级或者更低）来标记，以防止用户模式的程序访问到内核空间而发生页面错误。
Kernel space is flagged in the page tables as exclusive to privileged code (ring 2 or lower), hence a page fault is triggered if user-mode programs try to touch it.
特权控制机制是高安全等级操作系统中一个重要的组成部分，它能够提供系统恰当的安全保证级。
As an important component of high-level secure operating systems, the privilege control mechanism can provide an appropriate level of security assurance for the system.
