signed packages etc are valid and desirable features but
i consider them as the next step after basic work which is
on you

i would start with the following:

- was the "su" really a sign o breach? i mean not some
   your maintenance batch in background/cron/...

- if yes what about weak ssh passwords? you may consider
   pki-based authentication then

anyway, once compromised, you should rebuild tainted
systems from scratch, sorry :-(

wrt signed packaged i think there's some support in pkgng
but no personal experience yet

BR,
Oli
