前言
authorization VS authentication
Modeling Access Control
2.1 Access Control Matrix
前言 访问控制其实和linux中遇到的文件系统权限,apparmor是息息相关的 自我宣传一下.jpg 😄 linux 文件/目录 权限管理 AppArmor 访问控制 当然不看也可以~
authorization VS authentication authorization(授权)表达的是你能够做什么 authentication(认证)表达的是你是谁
Modeling Access Control 首先需要对访问控制进行建模 Subjects S Things in the system that can act 即执行者
Objects O Assets or objects in the system (acted upon) 资产/物体,可以被执行
Rights R What can the subject do to the object? 即S可以对O做的事情,即权限
在一个简单的Unix Model中,系统中各个物体映射到访问控制模型的结果如下: Subjects are processes(进程) p, q
Files are objects(文件) f, g
Rights (read, write, execute, append, own) r, w, x, a, o
2.1 Access Control Matrix 访问控制矩阵,subjects作为行,subjects+objects作为列,Rights表示subject可以对subject/object做的动作
