SELinux is enabled by default in Fedora. SELinux policy has booleans that can be used to disable SELinux for specific services or you can disable SELinux entirely. If you want to disable SELinux entirely, you can use system-config-selinux (install the policycoreutils-gui package if you don't have it) to do this graphically or set the value of SELINUX in /etc/selinux/config to disabled. You'll have to cold restart for this change to become effective.
