I was impressed with Mandrake 8.  Its not perfect, but their top
security level (for my latest desktop) was sufficiently tightened that
I actually moved to a more relaxed level for local file permissions.
Mandrake is Redhat and Bastille.

And OpenBSD has long been very, very tight on the network side of
things, but less so on the filesystem and setuid stuff.
