Can I use SELinux and RSBAC?
Yes, SELinux and RSBAC can be used together, but it is not recommended. Both frameworks (RSBAC and the SELinux implementation on top of Linux’ Linux Security Modules framework) have a slight impact on system performance. Enabling them both only hinders performance more, for little added value since they both offer similar functionality. In most cases, it makes more sense to use RSBAC without SELinux, or SELinux without RSBAC.
