这里是 Linux 安全模块（LSM）学习的起点，内容涵盖 SELinux、AppArmor 等主流安全模块。 不仅包含用户层如何使用 SELinux、AppArmor 等安全模块的实践指南，更从代码实现层面深入剖析 LSM 框架的设计原理，并提供调试 LSM 代码的方法与技巧。
This is the starting point for learning about the Linux Security Modules (LSM), covering mainstream security modules such as SELinux and AppArmor. It not only includes practical guides on how to use security modules like SELinux and AppArmor at the user level, but also delves into the design principles of the LSM framework from a code implementation perspective, while providing methods and techniques for debugging LSM code.
