存取控制机制 meaning in English
access control mechanism
access-control mechanism
Examples
- At present , there is still a great deal of problem in the application of the secure model of the distributed database . under common circumstance , the secure usually is self - contradict with vivid in the database , while customer wanting to get stronger and vivid capability , needing the sacrifice to the database secure in some extent , vice versa . based on distributed database system and secure characteristic , this text analyzed its database safe strategy and related secure model , the system appearance and operate rule , the system appearance and operate rule , studied the customer role management , safe strategy and the role authorition problem , specially emphatically studied the bell . lapadula model . ( including its basic concept , system appearance , related operation and the secure rule gather ) . according to the actual application environment , this text carried bell . lapadula model to entity to turn , through a research discover that model adoption compulsory secure strategy , attain a vivid secure control not easily , so increase the secure strategy of the independent access control mechanism to carry on " flabby " to the original model , and relatedly increased rule , put forward a new kind of secure mechanism - ddm ( the distributed database discretionary mandatory ) . turn the rule principle according to the ddm secure mechanism and entity , designed a secure controller of database - dds ( the distributed database secure distribute ) controller adopted ddm secure mechanism , and established the secure control mechanism of the dds secure controller
拉帕丢拉模型进行实体化,通过研究发现该模型采用强制性安全策略,不易做到灵活的安全控制,因此添加自主存取控制机制的安全策略对原模型进行“松弛” ,并相应的增加了规则,提出一种新的安全机制? ? ddm ( distributeddatabasediscretionaryandmandatory ,分布式数据库自主与强制性)安全机制。基于实体化规则原理,设计了一个采用ddm安全机制的数据库控制器? ? dds ( distributeddatabasesecure ,分布式数据库安全)控制器,并设置了dds安全控制器的安全控制机制。通过dds安全控制器在实践中的应用,本文分析了dds安全控制器的各项功能和安全特点,设计了实际应用中dds控制器的管理方案,实现了分布式数据库安全控制。 - The rule and the method are given for implementing the mapping from the former onto the latter . the system is composed of security information database , security managing module and privilege verifying module . firstly , it can process five types of authorization ( roles to users , functional modules to roles , module - partitions to roles , database objects to functional modules , database objects to roles ) ; secondly , it provides several access control mechanisms ( only one entrance , user authentication , menu level control , functional module level control , module partition level control , etc . )
系统由安全信息库模块、安全管理模块、权限验证模块三部分组成，可以进行多种类型的授权(角色授予用户、功能模块权限授予角色、模块分区权限授予角色、数据库对象权限授予功能模块、数据库对象权限授予角色) ，实现了多种类型的存取控制机制(入口唯一、用户鉴别、菜单级控制、功能模块级控制和模块分区级控制等) 。
