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…

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…

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…

在前面5篇博客中介绍了OAuth2和OIDC(OpenId Connect),其作用是授权和认证.那么当我们得到OAuth2的Access Token或者OIDC的Id Token之后,我们的资源服务如何来验证这些token是否有权限来执行对资源的某一项操作呢?比如我有一个API,/books,它具有如下5个操作: POST /books 添加一本书 GET /books/{id} 获取一本书 PUT /books/{id} 更新一本书 DELETE /books/{id} 删除一本书 GET…
