Course Introduction：SELinux (Security-EnhancedLinux) is a security subsystem in the Linux system. It provides an access control security mechanism and restricts the behavior of programs and users through mandatory access control (MAC) to improve system security. The core of SELinux is a policy-based mechanism, which can control different access permissions through different types of policies. In SELinux, there are three main policy types, including: role-based access control (RBAC), basic
