# SELinux in Debian

Thanks to Pierre Chifflier , Debian now has setroubleshoot packaged. The good thing about setroubleshoot is that it gives you a very user friendly message about the SELinux violations that occur on your box while you were doing something.

Now that something is very difficult to define (at least for Debian). My day job requires me to work on the RHELdistribution which has very good SELinux policy defined (Same is the case with Fedora). Here’s a list of things which Debian’s SELinux policy lacks and that RHEL/Fedora’s doesn’t

• acpi -V raises a violataion
• dmesg raises a violation
• apt-get update raises a violation
• You can’t suspend, that raises a violation
• nvidia module load raises a violation (Oh!! Well. That’s binary-only. But the same doesn’t raise a violation in Fedora)

So even though I’d love to use SELinux on Debian, I can’t. Basic tasks are seen as violation by the Debian SELinux Policy. Try out enabling SELinux in Permissive mode and install setroubleshoot. You’ll see setroubleshoot pop-up a SELinux violation every 5 seconds. Turns out that Debian’s SELinux policy is becoming just too too much secure and thus interfering with the user using the OS.
