Enable SELinux
Security-Enhanced Linux is preventing any access that is not allowed via security policies when in enforcing mode. We recommend to set SELinux to “enforcing”, and set the policy type to “targeted”.
After Linux installation this is usually the default. If this is not the case, to set this mode edit the file “/etc/selinux/config” as root user and make sure the following entries are present and uncommented:
SELINUX=enforcing
SELINUXTYPE=targeted
