Is there any ubuntu equivalent of BSD Kernel Security Level? If yes, how can one change the security level?
You mean securelevels?– meskobalazsAug 11, 2015 at 14:54
If you meant securelevel, this is a *BSD kernel specific security mechanism. Linux (and therefore Ubuntu) does not have such a solution.
There is an old thread on this on LKML by the way.
