在Oracle11g中,Oracle在安全方面有了很多的改进,而在网络权限控制方面,也有一个新的概念提出来,叫做ACL(Access Control List), 这是一种细粒度的权限控制.在ACL之前,我们对于有一些程序包,例如UTL_MAIL, UTL_SMTP等这些包,你可以利用这些包连接到外部的主机,而默认情况下,这些包都是都是赋予了public角色,所以可能会导致利用这些PL/SQL程序包的恶意工具,所以Oracle提出了一个新的概念来解决这个问题,那就是ACL. 在开始展开ACL之前…

开源网络准入系统(open source Network Access Control system) http://blog.csdn.net/achejq/article/details/51089996 之前接触过两种网络准入系统 1.微软 域控制器:主要通过软件层面准入,访问任何资源都需要终端与域控制器的准入,互联网采用ISA与域控联动.比较完整的解决方案,很牛,但是全部需要采用微软产品(严格上讲,不算是网络层准入,算是应用层准入,但整体方案非常强大). 2.Cisco NAC:主要通过…

role-based access control(rbac),指对于不同角色的用户,拥有不同的权限 .用户对应一个角色,一个角色拥有若干权限,形成用户-角色-权限的关系,如下图所示.当一个用户进行访问数据时,根据其角色判断其拥有的权限,限定其操作.通过django实现一个简单的rbac app,简要记录下过程. 1.实现效果 实现效果如下图所示,不同用户拥有不同角色,不同角色拥有不同权限.下图中只是对角色和用户两张表进行编辑和访问,当我们项目中还有其他数据需要进行权限控制访问时,只需进行两处设…

RBAC(Role-Based Access Control,基于角色的访问控制),就是用户通过角色与权限进行关联.简单地说,一个用户拥有若干角色,每一个角色拥有若干权限.这样,就构造成“用户-角色-权限”的授权模型.在这种模型中,用户与角色之间,角色与权限之间,一般者是多对多的关系.(如下图) 角色是什么?可以理解为一定数量的权限的集合,权限的载体.例如:一个论坛系统,“超级管理员”.“版主”都是角色.版主可管理版内的帖子.可管理版内的用户等,这些是权限.要给某个用户授予这些权限,不需要直接将…
