Re: SELinux, LSM, SNARE ...


I can probably answer parts of your email. :)

We're hoping that Snare 0.9.7 will be the last one that actually
requires it's own custom kernel-level changes.

With a little luck, the next version of Snare will piggy-back on the
kernel changes you're seeing on the linux-audit list, providing some
extra capabilities & a nice user interface.

If Snare's extra features prove to be useful to a fair number of people,
then they may be rolled into the mainstream daemon at some point in the

The current snare package (kernel + daemon + gui) probably has a role to
play in the next 12-18 months, until the key distributions integrate the
stable auditing code and start to become widespread, but the kernel side
of Snare should be considered to be in 'maintenance mode' only. The
daemon & gui will continue, and we'll try to preserve your existing
config as much as possible under the new kernel infrastructure.

So where to spend your time? Up to you obviously, but probably Snare for
older distributions (particularly 2.4 based), and the new audit
subsystem for any distributions that come out 3-6 months from now.
Hopefully Snare will help you ease the transition to the new code by
providing a familiar interface.
