How it works...
SELinux operates in two modes, Enforcing and permissive. When working in Enforcing mode, SELinux denies access based on how SELinux policy rules have been defined. These rules are a part of the guidelines that control the security engine.
When SELinux is working in Permissive mode, it does not deny access, but any actions that would have been denied in enforcing mode get logged.
SELinux rules can be modified to allow any application or service that would otherwise be denied in Enforcing mode.
