Setting SELinux modes for AL2023
By default, Security Enhanced Linux (SELinux) is enabled and set to permissive mode for
AL2023. In permissive mode, permission denials are logged but not enforced. SELinux is a collection of kernel
features and utilities to provide a strong, flexible, mandatory access control (MAC) architecture to the major
subsystems of the kernel.
SELinux provides an enhanced mechanism to enforce the separation of information based on confidentiality and integrity requirements. This separation of information reduces threats of tampering and bypassing of application security mechanisms. It also confines damage that can be caused by malicious or flawed applications.
SELinux includes a set of sample security policy configuration files that's designed to meet everyday security goals.
