How to enable SElinux

Hello everyone!!!
I have installed mokee(MK44.4-p880-150131-HISTORY) rom on my phone with 3.1.10-WerewolfJB_v010 kernel.
I want to enable SElinux but I dont know how, currently at my phones settings->about->SElinux it says disabled.
How can I enable it in permissive mode? Thank you
