Sun Solaris, OpenSolaris "OpenSolaris has launched a new project, Flexible Mandatory Access Control, to integrate the Flask/TE security scheme into their OS. This is the same underlying model implemented by SELinux, and follows other cross-platform Flask/TE integration projects such as SEDarwin and SEBSD. This is very exciting in terms of establishing compatible security across operating systems, particularly for Mandatory Access Control, which has traditionally been narrowly focused and generally incompatible. With FMAC, we're closer to seeing truly ubiquitous, cross-platform MAC security."

Well, the 12% (on x86 for reads) to 147% (on SH series processors for writes, and no that's not a typo) cpu overhead of SELinux is rather significant. (And that impacts heat dissipation and battery life as well, of course.) Not sure how this new OpenSolaris implementation will compare. I think the overhead is supposed to be somewhat lower in Linux kernel 2.6.24. We'll see, I guess.

My understanding is that one pays a performance overhead even with selinux "disabled", unless he manually adds "selinux=0" to the kernel boot params AND the option for SELinux to honor that boot param has been compiled in.
