Re: Some ideas and info.

hello nikolay, from one random selinux user to another, welcome to
the nsa's selinux list.

okay.  selinux was designed to add fine grained auditing and "mandatory"
access control because of concerns over the use in US government
departments of an over-20-year-old security model - i.e. ordinary
non-selinux-enhanced linux.

i presume that the nsa's expertise was best spent focussing on this
specific "lack", given that other research projects were concentrating
on things like PAX, MPPE support etc. (e.g. the http://adamantix.org stuff)

so yes, it'd be great to have additional security measures in place.

i think you'll find that gentoo (hardened) have made use of as many
as they can find.

however the people on _this_ list specifically focus on selinux -
perhaps on its own, perhaps in combination with other security measures
(like gentoo hardened do).

so, with that in mind, can i please ask you a favour?

can i "steer" you in the direction of adamantix.org, because i would
_really_ like to see debian have all of the adamantix.org stuff minus
the RSBAC stuff plus selinux stuff.

it's a bit unfortunate that a lot of this stuff requires a total
recompile of all packages, which is probably why gentoo has it a
bit easier.

Information I post is with honesty, integrity, and the expectation that
you will take full responsibility if acting on the information contained,
and that, should you find it to be flawed or even mildly useful, you
will act with both honesty and integrity in return - and tell me.
