第四章 介质访问控制子层-Medium Access Control Sub-layer 4.1介质访问控制子层概述 MAC子层不属于之前提到的OSI或TCP/IP架构的任何一层,这也是为什么这一层被称作了子层(sub-layer).事实上,MAC子层位于数据链路层与物理层之间,处于数据链路层的底部. 在这一章将重点讨论广播网络极其协议.在广播网络中,由于信道是共享的,存在一些复杂的协议来决定哪一台机器可以接入链路进行下一次传输.我们将介绍5种经典多路访问协议,以及两个实际例子(无线局域网的MA…

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…
