Securing FreeBSD 2.1.7.1

["-= ArkanoiD =-" <ark () mpak convey ru>]

nuqneH,

I am thinking on "hardening" FreeBSD 2.1.7.1 system to run a firewall on
top of it.. by implementing "securelevel 3" with some system calls
disabled/wrapped - like mount, mknod.. what else? Any ideas?

Note that i am not planning a big project, i just want to do a couple of
dirty hacks (one or two days of work in "non-dedicated" mode ;)
